Mobile Joint Objective Light Nonstandard Individual Role Powered Assault Armour Mark VII



The MJOLNIR Powered Assault Armour Mark VII is the seventh iteration of the infamous MJOLNIR Armour and easily the most widespread. It saw widespread action with the SPARTAN-IVs, IIIs and IIs. The armour featured a number of changes and reductions to its physical and integral functions.

Changes from Mark VI

 * Memory processing weave removed from basic designs to make the design cheaper.
 * Twin linked Fusion-Plasma Hybrid generators
 * A more robust shield with a faster recharge time resulted from this and a greater knowledge of shielding. (Grade 4 shield generator).
 * Expanded HUD systems, CTC and IFF combat systems for full integration to army level warfare.
 * Composite body armour of Titanium and AEGIS ceramic skin with resin bonded graphite composite carbon fibre layer and liquid crystal internal layer to catch spalling from penetrations of higher layers.
 * Under layer of interwoven plates of titanium and AEGIS nanocomposite form fitting and flexible body suit.
 * Integration systems for a wide range of 'clip on' equipment.
 * In addition to motion tracker the armour also includes a small forward facing AESA RADAR with an effective range of 100 meters. It is impossible to jam though and has a low chance of interception.
 * AEGIS plates coated in robust Nanotech Polymers allow the user to change the colour scheme of it, allowing localised colouring of the armour through the neural interface, rather than having to apply specialist camo schemes ground side.
 * Active A.I. transfer protocols allowing A.I.s to jump from one computer system or suit to another suit or computer system within short ranges or via wireless connections.
 * Standalone atmospheric insertion capabilities. A user in a suit can survive atmospheric re-entry, using limited energy shield airfoils and reinforced protection and shock absorption system, allowing users to survive impacting with soft surfaces (dirt, water, sand, mud) and maximum of mach 1.
 * Slipspace de-insertion capabilities when used in conjunction with G-66 Slipspace pods, allowing users to be slingshot out of slipspace and into real space for tactical insertions.

Helmet

 * A Variable electronically controlled non-reflective self regenerating composite visor with liquid glass material, protective and concealing sun shade and gold tint to protect from electromagnetic interference. The colouration and concealment can also be adjusted. Adaptive liquid display protects users from high intensity flashes, such as flash bangs, blinding LASERs and unfiltered sunlight without affecting vision. Visor is made of twin layers of single crystal quartz, providing armour resistance on par with high level ceramic armouring.
 * Anchor Point on helmet for thermal goggle systems and other systems, additional anchor points on the sides of the helmet for additional gear, such as battlefield cameras or vision systems.
 * A communication featuring powerful 'Agile Metamaterial' with ultra to to extremely high frequency communication systems and a range high enough to reach high orbit communication satellites and a short range radio system with a 6 kilometre range and a neural interface controlled throat microphone.
 * An Electronic Warfare suite utilising a 70GB electronic warfare computer, capable of gathering and jamming SIGINT ELNIT FISINT and COMINT systems. It also contains a highly advance protection system consisting of a number of attack, maze and defence barriers with set ups not sanctioned by numerous war treaties and a highly effective dummy barrier.
 * 130GB warfare assistance computer assistance for video storage, an Identification friend or foe transponder, video and audio storage and Unmanned vehicle interfacing. It also stores objectives, mapping information, long term weather reports and stored enemy information system.
 * A holographic HUD projected by a AC5 Heads Up Display. This displays weapon interfaces, including cross-hairs and ammo, targets, marked with red markers, team mates, marked with green markers, objectives, marked with yellow markers, biometric response from user and team mates, camera links from on board camera, fibre optic probes, weapon mounted cameras, team mates, unmanned vehicles and aerial or satellite recon, geological/meteorological information and mapping and shielding power.
 * Two helmet mounted flash lights, consisting of a high power 'white' halogen lamp, 'red' halogen lamp, an on board full colour camera/Night Vision Camera for short range recording and live video transfer and a LIDAR/LASER range finder. These are protected in the same manner as the visor.
 * Two stage Nightvision-/Infra-red nightvision system. This system uses a standard passive night vision system with long range viewing under low light situations, but can be augmented with a active infra-red mode, highlighting high-heat objects and giving it an ability to see through battlefield obscurants and view in situations where no light is available for passive nightvision. Each mode can be used together or separately.
 * Regenerative Chemical, Bilogical, Radiological and Nuclear Warfare system, with air filtration and protection against airborne agents. Due to the vacuum sealed nature of the suit, only the rebreather is hardened against these threats.
 * Enhanced audio receptors that can be actively tuned through the user's neural interface, record audio input and protect against loud noises. It is capable of tuning into a pin drop in the middle of a fire fight and can even accurately record audio communication through walls.

Armour

 * Heavy duty armour, using a five layer AEGIS ceramic composite, with a outer coating of titanium, providing ballistic defence and ablative energy defence with its refractive coating. Under that, is resin bonded AEGIS layer, which shatters incoming projectiles and is resistant to HEAT explosives and multiple impacts. This layer is made up of multiple tiles, to improve protection and multiple hit ability. Under is a energy absorbing non-newtonian liquid nanocrystal layer, which has a triple purpose. firstly, it absorbs kinetic and thermal energy from the high levels, then distributes it safely across the entire layer to prevent this from transferring to the user, secondly, to absorb any spalling from munitions of upper layer fragments, safely stopping them before they can reach the user and thirdly, provide a last ditch defence, being stronger and safer than 3 centrimeters of kevlar, without the bulk or weight. Under this is another layer titanium, which adds to the protection and provides most of the structural rigidity and support. Tertiary armoured body suit consists of nanocomposite titanium and AEGIS weave interlocked plates with non-newtonian liquid nanocrystal interior layer. Primary armour sections are resistant to at least two direct 15mm auto cannon hits and upwards of 15 .50 calibre hits before failing, while tertiary armour sections are resistant to just one 15mm hit and 6 .50 cal hits.
 * High strength triplex-titanium and nanotube weave over liquid crystal layer with underlying layers of radiation resistant layers, protecting from a full spectrum of x-ray and gamma radiation.
 * Titanium reinforced gauntlet provides increased resistance to damage against the outside of the fingers, providing structural support, prevents hyperextension of the digits and provides increased effectiveness against unarmoured targets in a so called 'knuckle duster' effect.

Sensors

 * Eye/Head Tracking systems allow the helmet to be combined with vehicles Target Acquisition Systems with out any need for interfacing systems.
 * Three stage motion scanner using passive infra-red, microwave sensors and KdV equation magnetic receiver. The Infra-red sensor uses all round 'sensor pits' that record infra-red movement around the armour, reporting back on it. The Microwave sends out frequent pulses in a 360 degree arc, recording movement it it's immediate vicinity, while the KdV magnetic receiver detects low end electromagnetic pulses, reporting back on sources of this electromagnetic energy, usually produced by living beings, or by shielding systems. This scanner is resistant to direct jamming. The scanner can also be modulated to operate as a receiver for electronic warfare.
 * Micro Active Electronically Scanned Array. This is used for terrain and target mapping and is highly resistant to jamming. The AESA is resistant to being detected and can be attuned to operate as a wide band receiver.
 * Micro sensors fitted through out the armour monitor the user, his health status, armour status and combat situation. This helps keep the user comfortable and keep the armour thermally invisible as well as provide damage report and response.
 * Terahertz Wave camera, utilising Terahertz radiation in a tight band, modulating frequency, to observe through solid objects at short range, giving limited capacity for observation through solid objects. This, combined with on-board target identification sub-systems allow for observation of the target, cross matching across multiple sensors for a full range of details on the target, such as race, size, armour, weaponry, injuries and heart rate.

Other Systems

 * The suit contains a pair of high power Mk. XXI CAESER Plasma-Fusion Reactors with a fuel reserve for 4 months on constant use. The reactor uses a high power polywell generator using Boron-11 and Proton fuel hoppers. The Polywell works be creating a powerful magnetic field through the use of six spherical electromagnetic coils. Inside the magnetic field, electrons injected are accelerated by the electric current. The electromagnetic structure confines most of the electrons and those that escape are retained by the electric field. This configuration traps the electrons in the middle of the device focusing them near the centre which produces a virtual cathode. The virtual cathode is used to accelerate and confine the ions to be fused which, except for minimal losses, never reach the physical structure of the Polywell. This produces a high energy plasma field, which is maintained in the reactor pack, giving it a 'fuel reserve' to be used, with the reactor working harder to produce more plasma as the suit works harder, while using the current plasma reservoir. When a new fuel hopper is inserted while the plasma resevoir is unusedit can be immediately catalysed into fuel. Unused plasma after reactor shutdown is cooled, scrubbed and ejected as a near harmless cooled plasma bloom. The power needed is achieved by temporarily hooking it up to a full sized fusion reactor for five minutes. After the introduction of the fuel, the reactor uses the fuel to maintain the power. The reactor produces no waste and what little radiation is produced is contained and subjected to nano-machine radiation scrubbers allowing it to continue for days at a time without venting it, allowing it to be invisible to any potential radiation detection measures. Heat produced on board is stored in primary heat sink with a operable time of three hours to ten days, depending on the amount of strain on the unit and can be vented via the heat exchange unit on the suit's rear. The ceramic heat sink is subjected to thermal energy absorption, turning a small amount of the power into electrical energy, making the armour extremely efficient. The reactor unit features a command controlled override, allowing it to be 'killed', shutting the reactor down safely or overloaded, producing a low yield nuclear explosion.
 * Installed 2606 Thermal Optical Camouflage system, providing both optical and thermal invisibility, at the cost of a limited lifespan. The system is tunable to adapt to different sensors.
 * The Waste Disposal filters gases and waste and removes unnecessary waste and recycles what is available for the internal water reservoir.
 * 13 Chemical Injection Ports are present and can be custom loaded. The usual load is biofoam and Medi-Cell reserves and can be supplemented with a wide variety of combat drugs, such as stimulants and reaction accelerators.
 * The armour has 90 minutes of air with a pressure controlled mixture intake.
 * Each gauntlet has two fibre optic probes, which can be remotely controlled by neural interface or plugged into weaponry, providing optical links and long distance probes, with a range of two meters.
 * Thermal Regulation systems are provided by water borne ancillaries from a internal water reservoir. These are warmed or cooled by alternating cryogenic and radiator heaters, to provide internal comfort and keep the external armour as a 'black body' against background thermal radiation.
 * The Reactive Liquid Metal Layer has gotten incremental improvements, increasing the ability of the user even more. The average running speed of a SPARTAN in the armour is 117 kilometers per hour, thier strength is tripled, capable of lifting, on average, 2250 pounds and jump up to 4 meters in height at 26 meters in length, with a running start
 * Pressure Suit for internal vacuum sealing and pressure control.
 * Magnetic Induction plate in boots for space walks on metallic surfaces.
 * Reactive Bi-Polymeric shock absorbing layer to protect from falls and increase endurance for long distance travel.
 * The armour has a inbuilt 3B Information module, which produces the image of a holographic keyboard on the visor upon command and users tracing sensors on the armour to track movement to record key strokes, allowing the user to type type in information without the need for a separate computer. It reads with a 99.8% reliability.
 * Maintenance free stealth coating, which is resistant to RADAR, LIDAR and even motion detectors through unique sonic absorption paint materials along with texture buffers that reduce the RADAR play back and radar resistant shape which further reduces its cross section, a reduction to IR Signatures which reduces its signature, even during extreme activity, to a black body, a liquid glass laminate that renders it UV invisible and provides some radiation protection, Cherenkov radiation disguising, heavy data encryption and emissions control (EMCOM).
 * It's stealthy design is reinforced by a magnetic suppression system that reduces the amount of electromagnetic radiation that the armour produces.
 * Hydrostatic Gel layer, which controls internal and external temperature and change it's pressure level to protect the user. The Gel Layer is inhabited by a small colony of nanites that protect it from becoming viscous and seal gaps.
 * Severe Weather conditioning, allowing the MJOLNIR to operate to extreme cold, extreme heat, high pressure and low pressure environments, through adapting the cooling, pressure and breathing systems, preventing the suit from overheating, freezing or suffering from the effects of extreme pressure differences.
 * The Polymerized Lithium Niobocene Capillary layer is sandwiched between the outer armour and inner layer. The Polymerized LiNb s poured into the capillary network, where it is applied to hundreds of thousands of microelectrical fields, allowing fractal crystallization of its geometries, allowing it to remain amorphous, but provide massive strength increase when effected by the piezoelectric effect. The capillary network is supported by five bladders of the liquid, to replace any lost, located on the calves, inside of the forearms and on the back, providing cushioning effects against high distance falls or assaults on high strength objects, usually tank canopies. The Capillary network has a handful of nanites fed through a one way valve from the secondary network, who are designated to repair gaps in the network, repairing breaches to prevent major leaks and rerouteing the capillary system should it be damaged.
 * The Secondary Capillary System, just underneath the first one, transports water and nanites around the body, acting as both a reservoir, recycling network and repair system.

Shield Generator

 * The MJOLNIR uses the ATHENS Mark XVIII Electromagnetic Shielding System which has a 3000 volt range with low intensity emitters and masking systems, obscuring its energy signature from a variety of spectrums and magnetometers.
 * Energy Shield shaping allows the user to adjust the shielding surface, allowing the projection of predetermined 'solid' shielding, similar in effect to a Jackal or Skirmisher's shield, allowing overlapping of shield surfaces to protect joints or armour weaknesses or formation of aerofoils, allowing for limited short range gliding or slowing aerial descent.
 * The possibilities of the shield shaping technology were enormous. While Doctor Halsey's initial designs suggested shield shaping technology could be used for defensive, or support purposes. However, as SPARTANS got a hold of Mark VIII armour, they got access to the shield shaping systems, and began to design their own programs for it. While this began as shaping customised shield layers, they began to emulate Sangheili energy weapons, then design their own, capable of preforming devastating damage to whatever is in their way. While their are hundreds of different patterns of shield manipulation, a few have become noteworthy.
 * Spartans have been known to create their own energy swords, designed to fight opposing forces with Energy Swords or other melee weapons at close range. These are difficult to use, but with training can come skill. These usually follow more earth like designs, with some Sangheili influence, but especially skilled Spartans may use one on both hands, though the energy drain can limit the time it can be used for.
 * Spartans have also emulated the energy dagger, a shorter variation of their sword, for use at short range and for quick, quiet executions. Spartans attempting to emulate the fighting styles of certain Sangheili use the Energy Dagger in their off hand and a sword in their main hand.
 * Spartans have used the shield shaping systems to equip themselves with knuckle dusters or bladed instruments on the knuckles. These are simple designs, that can be used for purposes such as disabling opponents at close range, cracking armour, or puncturing light armour, flesh and bone.
 * One of the more technologically complicated designs is a large, gauntlet like weapon, designed to deliver crushing blows. The Gauntlet features a large impact surface, with several bladed protrusions, depending on the creator and user. This design is extremely heavy, with an incredibly dense field that weighs several dozen pounds. By using the DAEDALUS SFS, the gauntlet can be lightened then suddenly its weight can be increased by gravitic reversal, usually at the moment it is swung. This helps it maintain its momentum and become incredibly deadly on impact. Armour, flesh and bone simply crumple under the blow, leading some Spartans to simply punch right through some targets. It can also cause incredibly damage to a Mgalekgolo, but not enough to kill it. The blow can also be used to crack open even heavy vehicles, multiple blows cracking open heavy armour plating.
 * One advanced technique uses a disc-like shield bubble containing condensed plasma, which uses the forearm shield emitter to either cool or heat the plasma. This disc is used like a boxing glove, punching a target, which then ruptures, creating a directional explosion/expansion of the condensed plasma either generating a white-hot explosion that melts through armour, flash-vaporizes flesh and generates enough concussive force to launch a full grown Sangheili back several feet, or creates a cryonic expansion, that flash freezes the target, capable of subjecting several individuals in a three metre area to intensely cold temperatures, in the area of -150 degrees Celsius.
 * A number of Spartans have improvised a radial shield burst, capable of reversing their shielding into a radial concussive blast outward from themselves, covering an area of a few metres, but scattering enemies, often useful for clearing the immediate area, but drains their shields entirely.
 * One of the more dangerous improvised shield weapons is a short range plasma projector. Using the plasma from the shields, ran through intense magnetic fluctuations from the shield emitters to render it super hot or cold and then accelerated to high speed out of the magnetic field. Because of a lack of plasma enveloping, this billows outwards, creating a high speed cloud of plasma, generating a flame/cryo thrower like effect. While this drains shielding, its perfect for clearing enclosed spaces, or pushing heavy infantry back. The effect usually on works out to ten metres.
 * One of the most powerful shield alterations made by SPARTANS, is the disrupter beam. The shield emitters and the shield is rerouted into a single, highly focused beam. This beam is fired from the user, completely draining their shields and knocking the emitters out for several moments, but once the beam connects with a target, the plasma billows out into a intense explosion. While short ranged, the penetrative, thermal and concussive effect of the beam means near instant death for who ever is hit, and in a short radius death is almost guaranteed.
 * Spartans have made increased solid-state shield armour, usually centred around their torso, shoulders, forearms, and sometimes in front of their faces, to greatly increase their ability to take fire before their shielding fails.
 * Hand held shields, emulating Kig-Yar Defence Gauntlets. Several patterns exist, from small bucklers resembling those used by Murmillio Skirmishers, to large shields covering almost the entire forward aspect of their bodies. These vary wildly, and generally replicate shields of ancient earth. They can also be used as improvised clubs or battering rams. These are usually ad-hoc uses, as more robust composite shield used by the UNSC is preferred.
 * The shield shaping system can be used to create air foils, creating wing suits out of MJOLNIR, allowing SPARTANS controlled descent with high agility.
 * The DAEDALUS Fall Safeguard System utilises the shielding emitters to produce a fixed electromagnetic field, facing downwards along the plane of the drop. This field pushes against the planet's magnetosphere and slows the user's descent to a manageable velocity. This makes it near useless in space operations, but allows the user to maintain a steady fall, stable enough to even be used as a firing platform.
 * The armour is now purpose designed to engage an 'Armour Lock'. Previously only a feature devised on a ad-hoc basis for MJOLNIR V armour but it's operators, and incapable of being reverse engineered on MJOLNIR VI, the VII can now, by design, preform a armour lock. By severely over charging the shielding emitters, and using upwards of 3% of the total fuel, the shield strength can be increased, and the field density quadrupled. Though this leaves the user immobile, they can survive incredibly heavy ordnance, if only for a brief period. As soon as armour lock is disengaged, the fluctuating electromagnetic fields generate a short range, high power electromagnetic pulse, in a outward pulse away from the user. The emitters are rendered ineffective for a few moments, requiring the shield to recharge.

Plug-In Modules
Like the MJOLNIR iterations before it, it can be modified with plug-in modules, designed to enhance the features of MJOLNIR, or provide some other benefit. These usually take the form of small pakcs that connect to the spinal interface and directly link to the main armour processor and reactor. These backs contain software and technology to enhance the tactical aspects of MJOLNIR.


 * The XM27 Responsive Holographic Form Emulator is used to create a near perfect replica of the user, using holographic light projections, which can be directed to manoeuvre away from the user or stay in the same place as them. The projections can be dispersed by gunfire, but when used by the Spartans in a coy manner, can produce startling results. They can be used to entice the enemy out of a defensive position, fake a retreat, to force a sniper to reveal themselves, distract an enemy or create the illusion of a larger force. It can only maintain one projection at a time, and even then it is relatively simple in programming, and is no where near as complex as a Ghost Emitter.
 * The XM90 Photonic Coalescence Emitter/Aegis is a hardlight emitter used to project a near impervious shield in front of the Spartan. It is incredibly resistant to plasma and kinetic projectiles, with only anti-tank ordnance being capable of overloading and dissipating the field. The shield is near static in accordance to the position of the spartan, and prevents them firing on a target, but can allow for Spartans behind them to find cover. Its generally used in situations where the enemy is expected to have high fire power, and a composite shield wouldn't cut it.
 * The XM91 Static Shield Emitter is used to produce a self sustained spherical shield on the position of the user. The shield is self sustained, in that it doesn't require energy input from a reactor to remain, but will not recharge either. It remains in the same position, should the user who deployed it move. It is made up of tessellating hexagons, and while is resistant to enemy fire, cannot withstand sustained amounts of fire from kinetic or energy weapons. It can sustain at least one burst against heavy weapons before failing. It is usually deployed when forces are under fire and require cover than be erected nearly anywhere. It is large enough to fit several spartans, and can be used to cover retreats or advances, cover the deployment of weapons or other systems, treatment of an injured comrade or as cover when under artillery barrages in the open.
 * The M805X Forward Acceleration System/Fulcrum Mitigating is a specialised system, using short range, high impulse plasma motors. These use a pair of rocket to quickly boost the user in a single direction, providing enhanced mobility for a surprisingly small package. These can be used to boost a user up to a second story window, propel them forward into close combat, preform high speed evasive dodges or get to cover quickly in a fire fight.
 * M29 Jump Jets are used for short range mobility enhancement. Taking the form of a large pack applied to the users back, they allow the user limited amount of air time, mitigating their weight and propelling them upwards, and in a direction. It consists of a pair of central motors, used for upward propulsion, with vectored nozzles for enhanced agility, and a pair of propulsion units on each side that adapt with the users centre of balance to propel them in any direction. This can be used to quickly scale buildings, safely drop from low altitude vehicles, scale large gaps and provides limited space agility. They are most often used for urban combat to move around near unhindered.
 * The M31 Thruster Pack is the much larger cousin of the Jump Pack, containing several groups of thrusters, providing total mobility in all axis. However, due to its size, bulk and weight, it is extremely limited in atmosphere, and used almost entirely in space. It allows users to quickly cross distances of space, and exfiltrate or infiltrate star ships or space stations. However, they are also extremely vulnerable to fire.

Variants
The MJOLNIR unit has a wide variety of permutations for different combat purposes. Each variant exists as a standalone unit, with different armour attributes, stealth capabilities and electronic packages. However, each unit still has a variety of shared modular elements, for field modifications. The modular elements include the pauldrons, chest plating, knee guards, helmet sub systems and numerous utility armour elements. Many MJOLNIR variants have subvariants, used for more specialised tasks, or increased abilities in a certain area. These subvariants are simple swap jobs, swapping the helmet and several components from the modular systems, allowing a user, providing he has the gear needed for a swap, to change up his variant based on changing mission requirements. Only a handful of variants are actually issued as standard, while most are now private ventures that are requisitioned by special forces and ONI for use.

MJOLNIR Mark VII
"The MJOLNIR is 500 kilos of the most advanced fighting technology in the galaxy, and the representation of fear incarnate amongst the Covenant, Pirates and Insurrectionists. Its yours, if you pass training."

- SPRTAN-013

The Default variant, while perhaps considered a little 'vanilla' by some SPARTANS, represents the finest balance between protection, agility, strength, stealth and hardware capabilities. As such, its one of the most widely used variants, being used by every kind of spartan, of every specialisation, from rifleman to point man, sniper to engineer, and beyond. This variant is manufactured by Misriah Armoury, though all development is carried out by the Material's Group of ONI Section 3.

MJOLNIR Mark VII/WR
"Intended to replace standard MJOLNIR configurations, the Warrior has instead been adopted as electronic specialist variant, serving admirably thanks to its increased computing power."

- Materials Group

The Warrior is a modified version of the default variant, with several changes to facilitate increased helmet armour at reduced visibility and increased system hardware, with enhanced computing power making it ideal for systems specialists carrying Hardened Uplink or other additional sensors, squad leaders with command network modules, electronic warfare specialists or sentries tapped into remote systems. While intended to replace the default Variant, its never been accepted as anything but a specialist upgrade. The Warrior is manufactured by the Materials Group alone.

MJOLNIR Mark VII/T
"Developed for Marine special forces, it represents the pinnacle of of MARSOC development and is one of the most powerful variants available in the field."

- Marine Special Forces Instructor

The Trooper variant was originally designed as the singular variant for non-augmented Marine special forces. Though it is their most commonly used variant, it has also seen limited uses with Spartans. It is stripped down, with reduced hardware and only the most basic system requirements, but this greatly reduces maintenance requirements, weight and length of repair times, meaning it can be used reliably in the field for much longer than regular variants. The Trooper is manufactured by Hannibal Weapon System, and most of its development is split between HWS and MARSOC liaisons.

MJOLNIR Mark VII/VN
"Developed by Lethbridge Industrial as a development platform for the most sophisticated, next generation technology, the Venator is the perfect hunter"

- Lethbridge Industrial Marketing material

The Venator is a special variant created by Lethbridge Industrial, as an exotic platform for advanced technologies. Initially developed as a next generation replacement for current MJOLNIR variants, it seems limited distribution at the moment. The Venator has a streamlined design, with reduced armour sections in a number of area, and redistributed plating with exceedingly angled, overlapping plates, giving enhanced protection over vital areas without increasing weight or reducing mobility. The helmet has a number of advance systems installed, with all new hard, soft and wetware installed. This gives it substantial processing power, though much of this is devoted to advanced visual sensor packages, designed for short ranged acquisition. It uses two clusters of visual sensors, each made of three optical and three thermographic sensors, designed to follower the user's eyes, providing unparalleled visual acuity. With an upgraded terahertz camera, and enhanced motion sensor, with strengthened magnetic sensors, the armour can also detect targets without a direct or clear line of sight. The Venator only sees limited distribution, with a significantly increased price limiting its more widespread distribution.

MJOLNIR Mark VII/CQB
"The Close Quarters Battle Variant is devised to win any close quarters firefight, with increased protection, mobility and reliability. It is unparalleled in its ability to allow you to kill a dozen men in as many seconds, and as many inches."

- Fred-104

The CQB Variant carries over from older CQB designs, improving K (Kelvin/Thermodynamic temperature) dispersal by a thermo-reactive dispersion system, that reduces heat damage from energy weapons and increased joint mobility, achieved by carefully redesigning and moving existing armour sections, allowing the user much more mobility, a great boon in close quarters combat. Along with that, it also uses tougher armour on the helmet and chest plate, protecting vital chest and head areas and expanded armour over the joints. The CQB armour is used almost exclusively by SPARTAN Assault Teams, allowing them incredibly agility and survivability in close combat, giving them a edge against any opponent. The CQB variant, like the Default variant, is developed by the Materials Group, but manufactured by Misriah Armoury.

MJOLNIR Mark VII/VG
"Hannibal Weapon Systems' own take on the classic CQB, it removes any non-necessary systems ad replaces them with increased protection, allowing the UNSC's best to do what they do best, up close and personal."

- HWS marketing materials

The Vanguard is a variant of the CQB, developed by Hannibal Weapon Systems for use by Spartans. Developed as a potential replacement for the CQB, the Vanguard ups protection in almost every field, increasing amount of armour on the body, covering weak points, reinforcing the helmet and reducing the visor to a small area. However, this comes at reduced spatial awareness, that can't be fully rectified by external camera and sensor upgrades, reduced mobility and reduced hardware in the armour, reducing processing power and the speed the armour can process data from the War Net. While produced in small amounts, it has been requisitioned for use in the 117th, for close quarters specialists and point men, and for 'Green' operations, where stealth, agility and electronics are not a requirement, but sees little usage outside of that.

MJOLNIR Mark VII/SOL
"Developed solely for the Army's top tier special forces, the Soldier variant takes all the best parts of the CQB and removes anything that's not needed. The result is an extremely fast, reliable and tough MJOLNIR variant that's proven so successful even SPARTANS are using it."

- ARSOC ExtraNet description

The Soldier variant is a more exotic redesign of the CQB armour, designed by the Materials Group as part of the Army Special Operations Command (ARSOC) for a tailor made MJOLNIR variant for it's top tier special forces. The armour takes the standard CQB design and technology, and augments it to match ARSOC's requirement. The helmet has been designed to greatly enhance protection, with a reduced visor profile, increasing protection for the user against gunfire and shrapnel. The armour has been streamlined elsewhere, focusing on close quarters protection, but cutting weight where possible, leaving it a trimmed down 'low fat' version of the standard CQB variant, without compromising on protection. As such, it has reduced hardware, fewer fuel ports, a smaller internal oxygen tank, less biomedical ports and several other utility features have been reduced in number or cut entirely. The Armour was internally designed and developed by the Material's Group, but is manufactured by Vestol Corporation. Despite being designed for the UNSC Army, substantial amounts have found their way into the hands of Spartan operators, or be requisitioned by them directly, who use it for its lower maintenance requirements, and increased reliability without sacrificing protection.

MJOLNIR Mark VII/WM
"Lethbridge Industrial does not name their MJOLNIR designs in irony, or for marketing. The War MAster is named as such, because its simply one of the most advanced warfighting systems ever created. Taking the age old CQB, and improving its design in every every, the War Master is lightyears ahead of the compeition, securing victory of the UNSC's best, on every front"

- LI Marketing Material

The tentatively named War Master is a variant of the CQB, developed internally at Lethbridge Industrial as its idea for a potential replacement for the CQB. However, like the Venator, it is packed with exotic technology, and like the Venator, has a significant price tag, even for a MJOLNIR unit. The War Master is designed to keep many of the features of the CQB, such as enhanced protection, agility, resistance to damage, but with two more goals in mind. Streamline the design where possible, without sacrificing protection or agility, and increase the capabilities of the armour. With this in mind, it has been outfitted with additional sensors, such as a magnetic anomaly detector and more refined versions of existing sensors. It's expanded systems also make it an excellent host for team leaders, or system specialists, allowing them to gather and analyse data faster.

MJOLNIR Mark VII/L
"We hit that son of a bitch in the head. 11.4mm Armour piercing round to the head. Any other thing should of been dead, grey matter outta their skull. This guy just turned to us, with that freaky looking skull helmet. Next thing I know, both my legs are broken and they've got a snap restraint on my wrists."

- Anonymous Insurrectionist

The Locus is a simple after market modification job of existing CQB variants, with Lethbridge Industrial taking CQB variants made by Misriah, and modifying them with in-house developed technologies. While many of these modifications are small details, such as enhancement to sensor packages and on-board systems, taking some components from the War Master, the most important feature is the newly designed helmet. The menacing, skull like helmet, features increased resilience, essentially being one, large, curved, heavily armoured plate, studded with microcameras to allow the user to see. The Locus also has plug in modules from the War Master in the helmet, with increased hardware for faster processing speeds, allowing users to gather and redistribute information at a startling rate. This makes it ideal as a cut price alternative to the War Master, albeit still more expensive than the standard CQB.

MJOLNIR Mark VII/RA
"Every radio; dead, every TV; dead. We had no idea what was happening, then the helicopter's searchlight hits the antennae over the radio station. Theres a figure, looks like some kinda monster, with horns and teeth, half way up, and then every single receiver, radio, TV, chatterpad and anything else that receives radio waves started blaring Flip music, at the highest volume. Bastard was just playing with us"

- Anonymous Insurrectionist

The Raider, made by Imbrium Machine Complex, is a more unusual variant of the CQB. Starting out as IMC's answer to an 'improved CQB', the Raider is only marginally more expensive than the existing CQB variant, but has a host of unusual features, the most noticeable being its unusual design. It is designed after the Oni, a being from Japanese folklore, and this design is intended to weaken the morale of the opposition. The truth is, the fact a Spartan team is on the field is usually enough to do that, and most Spartans laugh at the prospect of an armour to inspire fear, after all they are already fear incarnate. What is not be laughed at, however, is its electronic features. Designed to not only wage war on the enemy's sense of fear, but also their psyche, the Raider is designed to conduct psychological operations, not just by shock and awe, but by electronic subterfuge, with an enhanced electronic warfare package, capable of tapping into civilian and military communication networks, such as radio, TV and the Extranet, and jamming them and broadcasting its own pirate signal over these networks, usually with a pre-recorded or streamed communique. In one famous instance, it was used to drown out all major information networks on a colony with terrabytes of ExtraNet cat memes.

"The first in the Material's Group of experimental armour designed for defensive situations, the Protector represents enhanced protection in every way, and enhanced awareness. No Innie will ever sneak up on with this on."

- Spartan-IV instructor

The Protector is the Materials Group first prototype MJOLNIR unit designed for defensive operations against enemy forces. The Protector, for its role as sentry, security and defender, has a greatly enhanced sensor system over regular MJOLNIR variants, with a longer ranged, triplex motion sensor, fitted with its own autonomous computer capable of heavy, in-depth analyse of motion sensor readouts to give as much information on targets as possible, more effective LIDAR and RADAR sensors, with greater range and accuracy, and a short ranged magnetic sensor, all of which are more resistant to interference and jamming. It has enhanced armour plating, intended for resistance against sustained fire though at the cost of reduced mobility. While intended for security missions, providing sentries for high level facilities and defending vital positions, the Protector has seen front line duty as in patrols and as sentries and defending high level positions against incursion.

MJOLNIR Mark VII/D
"Designed by IMC, specifically at the request of the Office of Naval Intelligence, the Defender is used to secure the most important facilities, protecting the humanity and their interests, across the stars."

- IMC Marketing Material

The Defender is a variant of the Protector designed by Imbrium Machine Complex for use with the Office of Naval Intelligence, issued to high level, non-augmented, internal security to protect vital structures and facilities. As such, it is designed to have high mobility than the Protector, responding to emergencies faster, while keeping it's expanded sensors. The Defender, as such, has more balanced armour than the Protector, and also has a variety of electronic countermeasures, geared to preventing espionage and catching or eliminating interlopers. A few have been requisitioned by the 117th for sensitive operations.

"Imbrium Machine Complex is proud to unveil the Enforcer, designed for the most specialist defence operations, the Enforcer can go for long periods without support or relief, allowing operators to continue for long periods without fear of being compromised or worn down"

- IMC Marketing material

The Enforcer is a variant of the Protector, manufactured by Imbrium Machine Complex as a potential replacement. Designed for high endurance, long term missions, often without support, the Enforcer has many of the features of the Protector, such as enhanced armour and sensors, but has also been re-engineered in various areas to increase endurance, and fitted with additional electronic counter measures, to protect against potential electronic assaults on the armour, or the assets protecting it.

"We we're bunkered down, between two cars, looking down the street to the car bomb. Nobody wanted to go to that thing, and then this Spartan just strolls out, all casual. Bomb still detonated, but then that Spartan came walking right back. Sure, his armour looked a little charred, but all his limbs were still attached. That was some fine armour..."

- Anonymous Marine

The Explosive Ordinance Disposal is also another hold over from earlier sets but with new changes. The Helmet was designed to channel the pressure wave around the user's head, significantly reducing the likelihood of decapitation and features a almost solid titanium-AEGIS 'cage' to provide maximum protection, with the small visor section being the only possible weak spot, the joints on the armour have significantly increased protection and the armour has been designed specifically to reduce the number of grabbing edges on the armour, decreasing the likelihood of dismemberment. It has been designed specifically to protect Spartans during operations involving the handling of explosive ordnance by channelling the explosion away from them. The gauntlets were redesigned with triple piece ceramic plating to give them a ultra-agile ceramic gauntlet to protect their hands and digits from damage. It also features an expanded sensor system that can detect potential explosives, booby traps and IEDs, along with an ARGUS sensor. The EOD is used by Combat Engineers during operations where they are expected to deploy or disarm explosive devices, allowing them to survive should their expertise fail them. The EOD is developed by the Materials Group, but manufactured at their request by Naphtali Contractor Corporation.

The Grenadier variant is a specialised MJOLNIR variant used usually by heavy weapons experts or point men expecting heavy resistance, or even engineer specialist when they require more flexible mobility. The armour's chest, shoulder, knees, helmet, pauldrons, gauntlets, greaves and thigh armour are heavily reinforced against directed impacts, energy weapons and even resistant to explosive weapons. The heavily slanted form of the armour provides increased protection and defence against munitions. While the shield receives no additional power, users in this armour can expect to survive huge amounts of punishment before their armour is compromised, but at the cost of agility. To counter-act the increased weight, the motor system is squeezed for every last extra ounce of strength, giving the user similar strengt, reaction time and speed to regular users. While other, newer variants, boast 'enhanced armour', and usually do have this feature, they are no comparison for the amount of extra armour the Grenadier possess. The Grenadier Variant is manufactured by Chalybs Defence Solutions at the behest of the Materials Group.

MJOLNIR Mark VII/GUNGNIR
"Designed in parallel to the Spartan LASER weapon, it was designed as a MJOLNIR platform capable of utilising the weapon to its fullest capabilities. As such, it has advanced sensor and acquisition systems, capable of acquiring and tracking targets to huge ranges and as such, is capable of interfacing with a variety of other weapon systems for long distance anti-armour/anti-personnel duties."

- Hannibal Weapon Systems marketing material

The GUNGNIR variant is a specialised MJOLNIR variant usually issued to special weapon units engaged actively in counter-armour/counter-aircraft warfare or as specialised snipers. The unit consists of and entirely new electronics suite for accurate acquisition, diagnostic and engagement of enemy armour, airborne assets or infantry assets at increasingly large distances, making use of a sub network of embedded micro cameras, a single long range optical/passive infra-red/night vision capable camera and a flat pane AESA RADAR designed to track specific targets at long ranges. The armour unit itself is designed to be slimmed down, without compromising protection, with glacis like pauldrons and load bearing systems built into the armour on the thighs, knees and calves. The armour unit can actively identify targets at long ranges without the use of additional visual systems and engage them effortlessly. It can be augmented with an additional eye tracking night vision/passive infra-red capable camera for increased panoramic viewing to replace decreased POV. An additional version, the GUNGNIR/S is a version with increased stealth characteristics for operations by reconnaissance units and snipers. The armour is used by weapon specialists dealing with anti-tank weaponry or snipers, when stealth is not the number one priority. Initially designed to support the W/AV M6B G/GNR, it works with a number of other weapons to great effect. Hannibal Weapon Systems manufactures the majority of the GUNGNIR, though the Materials Group manufacture a select few components, and maintain development of the variant.

"Want to reduce the population of a standing structure to zero? Get the CQB. Want to sneak into said structure, get the Scout. Want to sneak in, and kill every living soul in there? Get the Commando"

- Anonymous Spartan

The MJOLNIR Commando variant is a specialised armour often used as armour for scouting, or forward elements. The armour design is stealthy, resistant to damage and lightweight and agile, giving an extremely adaptable and well rounded armour. The helmet contains advanced hardware and software packages, enhancing processing power and tactical awareness. The armour is frequently used by any team operating far ahead of the main force, needing a fine balance of stealth, mobility and defence, and is often used by reconnaissance teams when preforming reconnaissance in force, or by sniper teams operating in close support. While not as sensor-resistant as the Scout variant, damage resistant as the CQB variant or as reliable as other variations, it represents a fine point between all three. The Commando is designed and developed by the Materials Group, but manufactured by Naphtali Contractor Corporation.

MJOLNIR Mark VII/JUMP
"Those jump pack Brutes are were awful cocky. That is until we started jumping too"

- Anonymous Spartan

The MJOLNIR Jump variant is one specifically designed for use with the G/J and G-PACK, featuring streamlined features, improved helmet aesthetics to aid in great vision during descent operations, anti-gravity stabilizers on the chest, legs, back and arms, extra gel and reactive liquid metal crystal layers in the legs and feet and expanded nanotech reaction systems in the soles of the boots. Should the SPARTANS be expecting high atmosphere combat or engagement against the enemy in skyscrapers, orbital elevators or Arcologies or preforming in atmosphere jumps, the JUMP is the preferred armour. The Jump variant is developed by the Materials Group, but manufactured by Ushuaia Armoury.

"Re-engineered for light weight, high speed and high altitude missions, the Para variant is designed to allow special forces Operators to quietly get anywhere with their MJOLNIR."

- Ushuaia Armoury marketing release

The MJOLNIR Fallschirmjäger, more commonly known as the FJ or PARA variant, is a lightweight, high endurance armour designed for specialised airborne operations. It has reduced weight though protection isn't fully compromised, neither is the electronics suites. The armour was designed to be deployed when the SPARTANS have to preform airborne insertions, where the reduced weight is a necessity. The reduced weight also lends to increased endurance, allowing SPARTANS to operate for much, much longer. The Para variant is developed and manufactured by Ushuaia Armory.

"Naphtali CC asks you this, what is it that you need? Advanced systems? Heavy Armour? Advanced Stealth systems? None of that, as in the end, all you really need, is speed."

- NCC marketing release

The Strider variant is a modified variant of the Commando built by Imbrium Machine Complex. The Strider starts life as a stripped down Commando model fresh off the line from Naphtali Contractor Corporation. IMC then take these and begin refitting them to create the Strider variant. The Strider cuts down on many, 'unneeded' components, and trims fat wherever possible, with thin, lightened armour plating, reduced subsystems and hardware, RADAR system removed and utility functions cut down. As a result, the Strider is probably the lightest and most agile MJOLNIR variant in existence, at the cost of reduced protection, reduced sensors, reduced hardware and reduced utility functions. This makes it ideal for short, 'jaunt-combat excursions', as the armour lacks the ability to stay in a sustained fight.

"So recruits, can you tell me, how many SPARTANS can you see in this room? Just me? You'd be wrong. Lieutenant 038, come take a bow."

- Kelly-087 teaching a class of IVs

The Scout variant combines the best features of the Scout and Recon variants into one package. It uses not only improved stealth paint, infra-red masking and more advance anti-detection systems, but it also uses improved sensory and communication systems to mask it's presence. On top of that, it has two built in electronic warfare implements to improve SPARTAN and Marine mobility, in the form of a RADAR absorption system, which absorbs Radar signals and masks the SPARTAN and other UNSC units in the surrounding area, and a Motion Tracker Jammer which feeds motion trackers false signals through a variety of means and giving false, or zero returns. It is used, usually in conjunction with camouflage cloaks, for 'Stalker' Special Reconnaissance SPARTANS or Scout-Sniper SPARTANS, giving them a edge when in close proximity to enemy forces. The whole armour has been streamline, increasing agility and stealth capacity. The Scout is manufactured by United Aerospace Systems, though it is developed and select components made by the Materials Group.

"IMC is proud to unveil the latest generation of specialised Reconnaissance armour for SOCOM, with the capability to fit interchangeable warfare pods, capable of dominating any spectrum, anywhere, any time."

- IMC marketing release

The Recon variant shares design cues with its predecessor, and builds upon the Scout's design. The Recon variant has reduced weight, allowing for increased agility, making for an incredibly light weight, high speed variant that suffers slightly in terms of protection, but makes for an incredibly fast unit. It has a twin pair of electronic warfare pods, that can be exchanged for other units, to allow the user to act as a roving electronic warfare unit, assaulting the enemy's ability t communicate, coordinate and counter attack. Included electronic warfare pods are radio jamming pods, effectively cutting communications within a 200 metre radius and knocking RADAR's out of order, sensor jammer that confuses motion sensors across a similar range, decoy dispersion pod, that can launch NEMESIS Decoy Launcher munitions, such as flares, radio jammers and decoys, a cyber warfare pods that autonomously attacks enemy networks with a variety of methods, preventing them from coordinating properly and opening the way for cyber warfare specialists, ECCM pod that provides benefits for networked operators, such as automated frequency hopping, signal polarization and radiation homing to find those responsible, and the last electronic warfare pod is a small electromagnetic pulse generator. While MJOLNIR 'hard' system are invulnerable to EMP, their shields, and weapon systems are not, so the pod acts as a last resort system to 'black out' an area. It has a dialable radius from 5 metres, up to seventy, and can be used to disrupt enemy equipment, vehicles or other vital systems, once being famously used to crash a warship when detonated inside the command room. While developed by the Materials Group, manufacturing has shifted over to Imbrium Machine Complex.

MJOLNIR Mark VII/SK
"The Stalker variant is indicative of UNSC advancement in the post war period. Take the best technology the enemy has to offer, and make it even better."

- Anonymous NCC director

The Stalker variant takes in technology examined from intact examples of Brute Stalker Armour, and combines this with existing UNSC stealth technology to create a deadly close ranged armour. The Stalker armour takes the best of Scout and Recon armour technology, and brings in technology that allows for increased sensor jamming without exposing themselves, reduced audio output, reduced heat output and modified visual sensors that allow for easier acquisition of target, using full spectrum enhancement to detect and mark targets, regardless of cloaking and blocking obstacles, and is especially effective at short range. This variant is often used by Spartan teams who have to infiltrate an enemy position in close proximity, or quietly eliminate enemy combatants at extremely short range. While much of the high level technology was recovered, analysed and reverse engineered by the Materials Group, they have passed this on to Naphtali Contractor Corporation for manufacturing.

MJOLNIR Mark VII/IF
"The Infiltrator is an attempt to marry the technology behind the CQB and Scout. I say attempt, last month I manage to infiltrate a command centre and kill every officer in there without compromising my cloak. I'd say its pretty successful."

- Anonymous SPARTAN

The Infiltrator variant takes the Scout platform and adjusts it with more combat orientated focus, for SPARTAN teams that require both enhanced stealth capabilities, and direct action capability. While it has all the stealth enhancing capabilities of the Scout variant, such as increased stealth materials and sensor resistant design, it shares design cues with the CQB and SOL, with up-armoured design, external microcameras in the place of a visor and increased combat orientated protection systems. As such, it mixes the best of both worlds, in a powerful, albeit expensive platform. While they can be difficult to requisition, Infiltrator suits are some of the most favoured suits for when Spartan teams have to quietly reach a target, then decimate it in close quarters combat, such as direct action, or sabotage missions. The Infiltrator was developed and manufactured by Hannibal Weapon Systems, though much of it was based on the designs of the Materials Group.

"Our definition of 'Love' is making a shot to the head of a target 12 kilometres away using an high power sniper rifle and Augur sight... Love is knowing your target, putting them in your targeting reticule, and together, achieving a singular purpose against statistically long odds. If that is love, then call the Deadeye cupid"

- IMC manufacturer description

The Deadeye is a variant specially developed for sniper teams. The Deadeye has greatly expanded hardware and visual sensors, allowing the armour to acquire targets at extreme range, positively identify them and track them. The amour can synchronise with a variety of sensor feeds effortlessly, such as unmanned ground sensors, unmanned vehicles, reconnaissance aircraft and satellites, and can use these to track the target. It can the synch up with the targeting system in their rifle's scope, and synchronise data with it, such as target tracking, meteorological conditions and fire control if possible, before finally target locking. By manipulating the armour's control and linking this in to the target acquisition and the weapon's sight, the deadeye could, nanosecond by nanosecond, adjust the user's aim to maintain every shot is precise and on target, regardless of range, pervading weather conditions, or the conditions of the user. The Deadeye is manufactured by Imbrium Machine Complex.

- SPARTAN instructor

The MJOLNIR Operator variant is a specialised communications variant for use with reconnaissance units. The Operator variant shares much of the stealth technology with the Scout variant. It has enhanced capabilities for sending and receiving encrypted information, regardless of jamming or interception, and feeding this information to other units, or uploading data securely without fear or interception by the enemy. It can also gather substantial data itself from various radio wavelengths, various wavelengths of visible and non visible light and RADAR. Operator variants are often deployed at once per Reconnaissance team to provide a constant connection to commanders, or occasionally with Scout-Sniper spotters for reporting back. The Operator was developed internally at Beta-5, and is manufactured by Chalybs Defence Solutions, though they now fulfil orders for other units, including the 117th.

The Combat Information Officer variant is designed to gather, analyse and counter intelligence in the field, without support or expanded gear. It can intercept a variety of intelligence, decrypt and record it, while also recording a variety of sensor inputs, from RADAR, LIDAR, motion sensors and varying light wavelengths, and share it in real time amongst several hundred operators with time lag or delay. In addition, it has a expanded electronic warfare suite, capable of interception and decryption of sensors and communications, allowing it to easily feed false information. The CIO was developed by Acheron Security, with assistance from special forces operators.

The Pathfinder variant is a specialised stealth variant for long distance reconnaissance deep in enemy territory. The armour is designed to be highly resistant to most if not all forms of sensors, through a variety of materials applied to the skin of the armour, and counter-sensors installed in the unit, while also being capable of maintaining an uplink to friendly forces. As the name suggests, users go in first, to prepare the battlespace for a larger force. They can share data at a extreme rate, without giving away their position, allowing them to act, literally, as a drop beacon themselves. The armour is lightened and streamlined, with enhanced jamming capabilities built in, and can gather and relay information safely, allowing it to be used for first contact scenarios. The PF variant is usually equipped on a single volunteer Stalker who will go in ahead of the main force to bring the rest in. The Pathfinder was developed by Imbrium Machine Complex based on experience earned manufacturing the Recon variant.

The Tracker is a subvariant of the Scout, used for pursuing targets, potentially across vast areas. It includes vastly upgraded hardware and exotic sensors, allowing it to access data on the War Net and ChatterNet, and can create online profiles of targets. The on-board sensors, include upgraded visual sensors, capable of identifying a target by their heat signature, body mass, silhouette, gait, facial features, distinguishing feature or any of those combined with a 98.66% accuracy, and a variety of unusual sensors that can observe fingerprints, analyse DNA, track biochemical trails, look through solid walls for some distance and analyses a targets body at range, bringing up information on their current physical state. The Tracker is used by Spartan teams when they need to pursue a target, usually quietly, and quickly, regardless of lack of trail, data or time. The Tracker is made by Acheron Security, and shares many design cues and components with the CIO.

The Myrmidon variant is a subvariant of the Scout, made for Project Myrmidon operators. As such, it carries all the necessary stealth technology that the Scout variant carries, with enhanced electronic and cyber warfare packages, and is by default equipped with a super conducting weave, allowing each individual operator to vastly increase their operating power. With an increased price tag, the Myrmidon is deployed very carefully, and most often in situations demanding high protection for Myrmidon operators.

MJOLNIR Mark VII/EVA
"In space, nobody can hear you kick ass!"

The EVA Variant is designed for deep space actions with improvements to exoatmospheric endurance and mobility without the use of thrusters. In several improvements, it also includes micro gravity packs in the legs and arms to help stabilise during deep space ops, though the use of a G-Pack will greatly aid in this. It also has extended oxygen reserves of 120 minutes. It is used almost exclusively for Extra Vehicular Operations, whether for deep space assault, reconnaissance, ship boarding or engagement against enemy forces in counter-boarding naval warfare. Though developed internally at the Materials Group, infuriating has shifted over to Acheron Security.

The Engineer variant is a specialised armour tailor made for combat engineers during a variety of operations. It facilitates subversion, repair and reconstitution of a wide range of technology, including Human, Covenant, Forerunner and more. It has a number of built in tools for the job, meaning the operator doesn't need to carry an independent tool kit, and its central systems carry a wide range of specialised software and sensors, allowing it to observe, analyse and disseminate information to friendly units. While this unit can sabotage, repair or indeed, rebuild whatever it may come across with ease, its greatest power is the ability to record new pieces of technology it has investigated and feed back data on it, allowing SPARTANS in the field to gather intelligence on technology without bringing in working copies, or getting close. The exotic Engineer variant was initially developed by the Materials Group, but late stage development, design and manufacturing was done by Lethbridge Industrial.

MJOLNIR Mark VII/PR
"Developed for the Navy's special exploration teams, the Pioneer represents the pinnacle of safety, and security, to protect those leading the way."

- Acheron Security press release

The Pioneer is an extremely specialised version of the Engineer, that is used for the exploration and reconnaissance of hostile or unknown environments. Developed during the interbellum period, when Spartans were at a surplus and enemies to fight were in demand, UNSC Navy forces used several teams to reconnoitre, explore and map new worlds with potentially violent flora and fauna, and abandoned constructs, such as Forerunner structures. The armour is designed with hardware modules to map terrain, explore structures and link in to unmanned sensors and vehicles across huge distances. It has enhanced sensor packages, increased environmental systems for dealing with potentially hostile environments (though nowhere on the same scale as HAZOP) and autonomous electronic systems designed to tap into Forerunner or Covenant systems, enabling the Pioneer to breach these systems with ease, and ensure the safety of the user and their team. The Pioneer was developed from modified Engineer variants by Acheron Security, at the behest of ONI.

"The Rogue is a highly secretive development, originally one of the first generation, non-Materials Group developed and built variants, like the B, M and O variants, and remains one of the most sought after and unusual variants. When you see somebody in this, you know they're in this fight for the long haul"

- ONI Supervisor

The Rogue variant is a specialised unit, with an unusual goal. It is designed and built for Spartans who will operate independently of friendly forces and the chain of command for significant time, without the need for resupply. As such, its got expanded ports for additional reactor fuel, and increased ports for biochemical and medicinal implants, with improved trauma treatment systems and enhanced armour repair and upgrade subroutines in the nanotechnology control systems, meaning the armour can maintain current generation spec, with only brief connections to the War Net for patch downloads. It has enhanced network connectivity and sequentially delineated intelligence packs, which are vital for singular operators. The armour is optimized for individual operation in every way, making it one of the singular, most expensive MJOLNIR variants, with enhanced stealth capabilities, improvements to the sensor suite, expanded electronic warfare elements, increased personal protection without compromising agility and increased hardware and software components for gathering and storing larger concentrations of data. The Rogue was entirely developed and manufactured by Vestol Corporation, with aid from the Materials Group.

MJOLNIR Mark VII/WK
"The Wetwork is highly classified under the same level as the Spartan program, the mysterious VANIR encryption and for good reason. A variant designed to assassinate enemies of the government quietly, without leaving a trace. Damn pricey to do it, too"

- Anonymous SPARTAN commander

The Wetwork variant is a specialised variant of the Rogue, that's more expensive still, and classified under Encryption VANIR, its very existence being a government secret, and for good reason. The Wetwork unit is designed for the singular purpose of assassination in close quarters, by a single operative against opponents, while leaving no trace behind. While it has little need for the increased endurance of its parent variant, the Rogue offers, dropping increased fuel load and additional biomedical ports, it does still carry enhanced armour repair and upgrade subroutines, and still has enhanced network connectivity and sequentially delineated intelligence packs, but has a multitude of new systems. It has greatly expanded electronic warfare systems, capable of autonomously jamming enemy sensors, and hacking enemy systems, opening it up for the operator and erasing data behind them, leaving no digital footprint or recording. In addition, the armour has expansive upgrades to the reactive systems and liquid metal crystal layer. This allows for the user to react faster, move faster and exert more force, with reaction enhancing systems linked into their neural interface to decrease their reaction time, allowing them to perform incredible feats of agility and eliminate targets effortlessly, even before they knew they were under attack. This variant is extraordinarily rare, only being deployed to a rare number of Spartans who qualify to use it, and have good reason to. It is often used in operations to eliminate enemies who threaten the very fabric of the UNSC. The Wetwork variant was made by the Materials Group, based on the Rogue platform, but with specialised components, such as hardware and software systems made by request by Lethbridge Industrial.

- Anonymous Navy Officer

The Hazardous Operations armour is designed for going into situations where other MJOLNIR units simply wouldn't survive. It is designed to survive worlds with crushing pressure, acidic atmospheres, extreme temperatures, high radioactivity and unbreathable conditions, and can be updated or modified to survive more. The armour is tested to survive temperatures from 700 to minus 240 Celsius, which allows it to survive worlds of extreme volcanism, where lava is a regular and dangerous hazard, worlds extremely close to their local sun with intensely hot conditions, or worlds so distant they barely see the sun, or with exotic cryovolcanic effects. The armour is rated for pressure of 120 MPa, allowing users to survive on worlds of intensely high pressure, and dive to deep water areas without fear of being crushed, all the while the armour's interior systems adapt to the pressure to prevent the user from getting decompression sickness, regardless of ascent or descent speed. All components used on the armour are corrosion free, and can resist extremely acidic conditions, allowing the user to deploy to a world that is so hostile the atmosphere would begin to melt through the exterior armour of regular MJOLNIR units. Its radioactive shielding is also hugely expanded, allowing the user to survive radioactive conditions that would otherwise irradiate normal MJOLNIR users. Lastly, the on-board air filtration unit is extremely complex, with nanotechnological systems that constant renew the filters and act as secondary filters themselves, allowing the user to breath in near inhospitable atmospheres, such as those mentioned previously. In support of this, the armour also has larger internal air supply, that can be fed with specialised mixes for differing environments. The internal, environmental control level is extremely beefed up, in order to protect the spartans from the environment around them, regulating internal temperature and pressure so as to protect the user at all times. The armour does all of this without sacrificing protection or mobility, but does suffer in other respects. It has little to no stealth capability, and nanofibre camouflage must be reapplied as most environments simply destroy it, external gear and weapons often don't survive as well as the armour, and external sensors are cut to a minimum, to reduce components that could potentially break in any condition. This gives it a lack of flexibility in the field, compared to other variants, but allow it to survive conditions so hostile most other variants fail. Developed internally at the Materials Group, manufacturing has been picked up by Acheron security to keep up with demand.

"Lethbridge Industrial is proud to showcase our newest design, the Ranger. Using the base design of Hazardous Operations armour, we at Lethbridge have strived to design armour more sufficient for heavy combat scenarios, while surviving extreme environments."

- LI press release

The Ranger is a spinoff of the HAZOP armour, designed and manufactured by Lethbridge Industrial. A surprisingly different design from the usual high-tech, highly exotic designs of Lethbridge Industrial, the Ranger is designed to bridge the gap between the Hazardous Operations Armour and more regular units. As such, the Ranger is designed for hazardous operations, being capable of surviving extreme heat and cold, high pressure environments and high radioactivity, though the anti-corrosion properties have been toned down, and all the environmental features are not within the same high tolerances as the HAZOP. To fill its role as combat orientated, the Ranger features reinforced armour for increased protection against fire, with many design cues from the War Master and Locus, and takes numerous effort to bring back sensor systems lost on the HAZOP, giving it increased flexibility in the field. The Ranger also has reinforced, self regenerating air filters and increased on-board air capacity. The Ranger is used when expecting heavily armed enemy combatants in hazardous environments.

The Amphibious variant is an extremely specialised variant designed for aquatic operations ranging from deep water to close to shore operations. It was designed and manufactured by Hannibal Weapon Systems, based on the temperature and pressure protection systems of the HAZOP. The Amphibious has the same level of pressure resistance, being capable of diving to extreme depths, while maintain armour integrity, and can survive extremely cold temperatures, usually associated with deep sea environs, but can also survive high temperatures, so as to survive underwater volcanic vents. The armour is specially constructed and designed so as to resist prolonged exposure to underwater environments. As such, it is corrosion resistant, and delicate components are protected or reinforced, allowing it to remain in salt or fresh waters for long periods of time, or even waters with a high PH level. The armour also has reinforced pressure systems and temperature control, to protect the user regardless of depth and cold, and protect them from decompression sickness. It has a on-board, internally based aquatic adaptation system, which consists of an pair of artificial gills, using a refined version of the Bodner method to remove oxygen from water at a exceedingly high rate without producing vast amounts of waste materials or waste energy, ensuring stealth and safety in missions involving traversing deep water. Internal pressure controls, mixed with pressure controls of armour allow users to avoid decompression sickness. In support of this, it also has a on-board air supply, with increased supply and variable air mixes and pressure control for differing circumstances. The Armour cuts down on the external RADAR, instead packing high power lights intended to pierce murky depths, and a on-board SONAR system, with varying wavelength emitters and receivers, that can avoid jamming and act as a receiver, for other sensors, and underwater noises, such as vehicles. The hands and feet have variable surface controls, allowing them to adapt into flippers to allow for enhanced movement underwater. The last feature is a pair of water jets installed on the rear of the pack, allowing for high speed movement, without exposing themselves to enemy sensors, allowing the user to propel themselves at highspeed, underwater and on the surface, and can actually act as a limited jetpack like system, boosting them out of the water with 3 seconds of water in the internal reservoir. While regular MJOLNIR variants can operate underwater, and are fully buoyant, they can incur significant issues due to exposure to water, salt, beginning to lose functionality, such as sensor breakdown and other system failures, whereas the Amphibious can do this for hours. The Amphibious are used by Spartans if they have to perform operations against deep water targets, or deploy in close to shore operations, such as special operations against water or close to water targets, infiltration of a location by waterways and spearheading amphibious landings.

MJOLNIR Mark VII/CO
The Command Variant was designed especially for the commanders of the IV Program. Outside, it is near enough the same as the normal armour but internally it features a wide plethora of changes. Along with a commander neural implant in the user, it features an expanded neural net system designed to communicate with larger amount of forces, along with dealing with larger amounts of data going in and being sent to the troops under the users command. Along with that it features a super conducting processing weave for housing an AI. The variant was essentially a modified set of normal armour, allowing COs to use the armour of their preference. The armour is fitted with improved networking modules, to allow the user to link to the forces under their command more easily and integrate units seamlessly. The armour is equipped on COs and XOs down to section command, allowing A.I.s to survive even if superior officers are neutralised or terminated.

The CO variant is not a true variant in itself, its a special modification of hardware and systems applied to a standardised variant, such as a CQB variant, or EVA.

MJOLNIR Mark VII(I)
The MJOLNIR Mark VII(I) was probably one of the most important 'variants' though that term is not entirely correct. It was the result of almost 75 years of careful trial and error from the IV, to creating a powered assault armour that could be worn by non-augmented users. It is near identical to the standard version but with additional plug in hardware and software changes

The integrated feedback system is the most important modification, this prevent soldiers from killing themselves with simple movements. The feedback system is a sophisticated software and hardware package, that every nano second computes and applies adjustments to the armour's systems, passively adjusting the user's movements, preventing them from injuring themselves. This feedback system taps directly into their neural net and adjusts the suit thousands of times a second, so that a non-augmented human can use it safely. In order to do so, the strength, speed and reaction increasing capabilities of the armour are reigned in slightly. Performance of other systems is not impacted.

This results in a non-augmented human having much greater strength, reaction times and survivability in the field. The unit is incredibly rare outside of the SPARTAN unit, only rarely being deployed by specialist teams from the Office of Naval Intelligence's Clandestine Activities Group, select teams in Section three's Beta-5 Division, and a handful of units from the Marine Special Tactics and Operations force and Army Combat Applications Division.

Like the CO variant, they aren't true variants in themselves, but modifications of existing variants.

MJOLNIR Mark VII 'Hayabusa'
When the request for a new iteration of the MJOLNIR Armour was released to major companies and developers in this field, RKD heavily integrated their Hayabusa design into that of the VI, along with the UNSC supplied power supply and shielding to produce the MJOLNIR VII Hayabusa. Like the VI Hayabusa, it has a greatly reduced weight over regular MJOLNIR, being one fired light than MJOLNIR Mark VII, and has increased EVA capabilities and load bearing an anti-strain systems for heavy lifting, but like the previous Hayabusa variant, is is slower, and less dexterous. It also had reduced on-board hardware and limited capacity for plug in modifications. The Hayabusa variant was rejected by the Ordnance Board, though elements of it's design were used in MJOLNIR to improve various systems without impacting current performance.

MJOLNIR Mark VII 'Security'
Misriah Armouries produced their own design, the VII Security variant, noted for its throw back to their V prototype from the thirties. Though it did gain some favouritism amongst the board of ordnance, it was turned down. This version was noted for its increased hardware over the chosen design but had a noticeable lack of stealth properties.

Up Armoured/Collar
The Mk VII can mount a series of different collars to suit a variety of combat purposes, without adversely affecting capabilities.


 * Collar/BreacherSupplementary Composite Gorget Armour (Pattern Alpha)
 * The preferred attachment for point men and combat engineers, the full gorget is of similar design, internally, as the half gorget, covering from ear to ear and covering the front aspect, going up to the Adam's apple. The armour plate has minimal impact on manoeuvrability and doesn't limit visibility.


 * Collar/Storm TrooperSupplementary Composite Gorget Armour(Pattern Beta)
 * A curved gorget piece which covers half of the neck, on left or right sides, is often employed by close quarters units to great one, well armoured side, to present as their 'front', The armour uses a number of ceramic tiles encased in a resin aggregate, which itself is sealed in a titanium cover, with a non-newtonian layer on the inside. The armour works as firstly rounded armour, then as slanted tiles inside that, increasing effectiveness. It protects from the chin to the back of the neck, covering the whole neck without limiting visibility of manoeuvrability.


 * Collar/GrenadierSupplementary Composite Gorget Armour(Pattern Gamma)
 * A gorget piece modelled on improvised armour deployed on Mark IV Grenadier prototypes, the Collar/Grenadier is a heavy armour piece that covers the 90 degree hemisphere to the left or right of the SPARTAN's head, partially obscuring their view but greatly boosting their defensive capability, protecting their neck and elements of their head. It's construct consists of a double layer of AEGIS tiles encased in a trio of non-newtonian shock absorbing layers inside a rounded, heavy titanium shell, with thinner layers on the inside to prevent deflection of fragments or stray munitions into the head.

Up Armoured/Buckler
Buckler units are used to enhance forearm protection during close combat environments.


 * Buckler/PointmanSupplementary Composite Wrist Protection (Pattern Alpha)
 * The Buckler armour unit consists of a small sandwiched plate of titanium, AEGIS and graphite. The plate is adjustable and protects the wrist of the user, while also providing some extra defence to other regions. The are particularly favoured by point men for breaching, shoulder first.


 * Buckler/ReconnaissanceSupplementary Composite Wrist Protection (Pattern Beta)
 * The Recon Buckler is a lighter alternative, with a small diameter shield and two titanium plates attached to adjustable hinges, allowing it to move more freely.


 * Buckler/CommandoSupplementary Composite Wrist Protection (Pattern Gamma)
 * The Commando Buckler is a heavy duty armour unit, using a semi-circular shield with additional plating. It consists of a AEGIS resin bound in a circular form, with titanium plating and reinforcement bands. The armour is designed for heavy duty close combat and maximum protection, at the cost of reduced mobility.

Up Armoured/Bracer
Bracer reinforcement is used to substantially increase forearm protection, giving point men much heavier protection for their arms, particularly useful in a close quarters melee, where the increased armour can allow them to parry with their forearms.


 * Buckler/GrenadierSupplementary Composite Forearm Protection (Pattern Alpha)
 * The Grenadier pattern bracer racer reinforcement is used to substantially increase forearm protection, giving point men much heavier protection for their arms, particularly useful in a close quarters melee, where the increased armour can allow them to parry with their forearms. It uses a sandwich of composite armour bound in titanium reinforced nanotube cabling.


 * Buckler/BreacherSupplementary Composite Forearm Protection (Pattern Beta)
 * The Breacher pattern Buckler is a much lighter alternative, with heavy duty titanium armour units, with nanoyube cabling holding it together. It is a lighter alternative to the Alpha pattern bracer and can be used as additional storage hardpoint.

Up Armoured/Pauldron

 * Up Armoured/Multi-ThreatSupplementary Composite Pauldron Armour (Pattern Alpha)
 * In a trade off between additional protection and increased weight, the Multi-threat pauldron succeeds as additional, heavy armour protection, without severely reducing agility or mobility. The armour can be applied in place of existing armour plating. The plating consists of a Titanium shell with AEGIS tile inserts backed onto a graphite composite layer.


 * Up Armoured/GlacisSupplementary Composite Pauldron Armour (Pattern Beta)
 * The Glacis pauldron is designed to bolt on top of existing armour to substantially boost protection, at cost of weight and reduced mobility. The plate is designed to act like the reactive glacis plate of a tank, having a steep incline to give it effectively thicker armour and improved chances of deflecting munitions. The armour consists of a number of slanted sections, intended to always provide a slanted face to opposing enemies. ON the surface layer of the armour is a non-conductive shell with a interior layer of electrically conductive metal and then the insulatory shell. When this is breacher, a high power discharge is created, vapourizing the munition of dispersing the energy munition. Inside the armour is a number of AEGIS tiles, backed onto a non-newtonian shock absorbing plate within a graphite sheath to catch spalling, sandwiched in a thick titanium shell. The armour bolts directly onto previous pauldron units, allowing it to be easily removed to replaced when it is no longer effective.


 * Up Armoured/SecurityHeavy Duty Supplementary Composite Pauldron Armour (Pattern Gammaa)
 * The High Security Pauldron is a heavy duty, well rounded pauldron, designed to provide a high increase in protection without critically reducing endurance and agility. While not as protective as the High-Threat shoulder armour, it's rounded structure, heavy titanium bar enforcement, AEGIS plating and high-strength titanium casing and reinforcement ads give it high armour protection.


 * Up Armoured/Base SecurityLightweight Supplementary Composite Pauldron Armour (Pattern Delta)
 * Unlike many other supplemental armour units, Low Threat armour is actually much lighter than regular armour. Its rounded, light weight titanium structure, with AEGIS tile reinforcement provides an option when soldiers wish to increase their agility and endurance.


 * Up Armoured/OperativeLightweight Supplementary Composite Pauldron Armour (Pattern Epsilon)
 * The Operative is modified from older generation Operator shoulder designs to provide the most light weight shoulder unit, without completely compromising armour. It consists of a titanium plat on the surface, with a sandwhich of electronically conductive metals then a pair of titanium struts holding it on. When the inner layer is breached, it emits a high voltage discharge, melting the ammunition or dispersing the energy munition.

'''Up Armoured/Utility

 * Up Armoured/ChobhamSupplemental Composite Armour
 * Chobham utility armour is a thick plate of composite armour, with AEGIS tiles bound in a resin ceramic, within a titanium shell, back onto non-newtonian shock absorbing layers, with graphite plating to catch spalling.


 * Up Armoured/NxRASupplemental Reactive(Non-explosive) Armour
 * Reactive utility armour consists of a high output electric reactive armour plating, using a titanium case backed onto a non-conductive layer, within which is a sandwich of conductive metal, which when breacher generates a high power electrical discharge, vaporising enemy munitions, kinetic or energy.


 * Up Armoured/GrenadierSupplemental Composite Knee Guard 
 * Supplementary knee armour modelled on Generation 4 Grenadier Knee Guards. Larger knee units encompassing from the bottom of the knee to the top in a circular defence, with upgraded titanium and AEGIS reinforced plating.


 * Up Armoured/GrenadierSupplemental Composite Elbow Guard
 * The Supplementary Elbow Guard, modelled on Grenadier armour, is a heavy titanium/AEGIS composite plating designed to protect the exterior of the elbow, at the cost of reduced mobility.

Up Armoured/Torso

 * Up Armoured/RangerSupplemental Composite Fauld Armour
 * Ranger Fauld armour is specialised plating designed to attach to the waist hard points, allowing SPARTANS to mount circular armour plates, using titanium shells with AEGIS resin triplex tiles inside, that are designed to cover the hip and joints to provide increased protection without severely limiting manoeuvrability. They also serve as additional hard points for mounting equipment.


 * Up Armoured/Point ManSupplemental Composite Chest Armour (Pattern Alpha)
 * Point man composite chest armour consists of two titanium shells with overlapping AEGIS tiles inside that fit over the chest plating. The two plates are individual so they can be worn separately to augment protective capabilities. On top of that, it mounts additional hard points for carrying equipment.


 * Up Armoured/Base SecuritySupplemental Composite Chest Armour (Pattern Beta)
 * The Base Security plate is a simple option for increasing defence, using a titanium shell with AEGIS tile inserts that bolts onto the chest plating, to augment the user's defence.


 * Up Armoured/Counter-AssaultSupplemental Composite Torso Armour (Pattern Alpha)
 * The Counter Assault armour is a additional torso armour, desined to protect the vulnerable torso plating of MJOLNIR armour. The plating consists of multiple titanium plates with sandwiched layers of overlapping AEGIS tiles backed onto non-newtonian shock absorbing layers with graphite composites sandwhiched between the layers.


 * Up Armoured/Counter-AttackSupplemental Composite Torso Armour (Pattern Beta)
 * The Counter Attack is a light weight response to the Counter Assault, using a thin titanium shell with overlapping AEGIS tiles with shock absorbing layers, designed to accommodate for lightweight, close combat actions.

Up Armoured/Helmet

 * Up Armoured/GrenadierSupplemental Composite Helmet Armour (Pattern Alpha)
 * The Grenadier helmet armour is the first generation of helmet defence, designed to increase the defensive capability of the user's helmet armour, as well as provide a hardpoint for mounting additional vision equipment. It consists of a titanium shell with internal AEGIS resin, with graphite layers surrounding it. This armour is kept on a slant, providing a glacis like plate.


 * Up Armoured/CQCSupplemental Composite Helmet Armour (Pattern Beta)
 * The CQC pattern was the follow up the Grenadier pattern, using a titanium shell with AEGIS resin internal layers. Though not as thick as Grenadier pattern units, they still provide increased defensive power.


 * Up Armoured/Supplemental Composite Helmet Armour (Pattern Gamma)
 * The Gamma pattern plate is a lightweight alternative using a plate of electric reactive armour on the head, providing a one hit defence against munitions capable of penetrating the helmet.

Command Network ModuleAN/PYK-308 CNM
The CNM provides additional command and control systems for MJOLNIR that speeds up the flow of information between subordinate units and the linked commander, allowing soldiers to be more readily updated with their specific information for combat proficiency. With the aid of an A.I. this information can be compiled and analysed at increased speed and presented to the user.

Chemical/Biological/Radiological/Nuclear Protection SystemM227 CBRNPS
The CBRN attachment increases protection in hazardous zones. Compared to the normal CBRN systems of the MJOLNIR armour, it has much more resistant triple filter system with week long life span and internal diagnostic systems, and forty additional minutes of internal air supply.

Aquatic Adaptation SystemM280 AAS
The AAS is a system that bolts onto the ordinary air filters of the SPARTANS to provide them with a means of near permanent supply of air underwater. The artificial gills use a refined version of the Bodner method to remove oxygen from water at a exceedingly high rate without producing vast amounts of waste materials or waste energy, ensuring stealth and safrty in missions involving traversing deep water. Internal pressure controls, mixed with pressure controls of MJOLNIR allow users to avoid decompression sickness.

Hardened Uplink Module (Generation 1)AN/PSQ-706 HUL
MILINT acquisition device for uploading sensitive information discovered on the battlefield to encrypted ONI or UNSC servers. This generally serves as both a standard and holographic camera, capable of taking images in the visual, ultra-violet and thermal spectrums and able to take both streaming video feed and ultra-high-resolution photographs of any intelligence discovered in the field. This is mostly used by advanced reconnaissance specialists in high-risk behind enemy lines operations.

Hardened Uplink Module (Generation 2)AN/PSQ-707 HUL
The HUL (2) is a first generation magnetic anomaly detector, devised and issued in limited numbers in the fall of 2552. The HUL (2) allows operators to scan within a forward arc up to 200 metres. It uses four conjoined arrays with narrow but overlapping scanning parameters to provide a distinct and wide band view of electronic systems. Anything with a high EM output, such as plasma and magnetic weapons, FELs, energy shielding, a variety of energy reactors and ignition coils. The system is often used to hunt down infantry or vehicles in narrow confines and tight combat areas, with the information generated by it uploaded to local War Net systems, allowing friendly forces to see its output.

Hardened Uplink Module (Generation 3)AN/PSQ-708 HUL
The HUL (3) observes emissions in the EM spectrum such as radio, RADAR, microwave transmissions, and is useful for determining the location of enemy C&C elements on the battlefield, or for ensuring that primary communications arrays are eliminated before an initial stealth assault commences. They are extremely helpful in determining where to set up communications disruptors as well. These monitors are generally issued to cyber/electronic warfare specialists in the Spartan companies, and in some rare cases, to communication specialists in Spartan command teams.

Hardened External Sensor Array (Generation 1)AN/PSD-889 HESA
The Hardened External Sensor Array is a specialised system used for long range detection of enemy forces. It mounts a exceedingly powerful optical scope with optional passive infra-red and night vision filters, allowing a single operator to view targets at long range under a variety of sensors. This sensor can actively identify targets with its twenty times zoom and track these targets in day time, and through minimum foliage.

Hardened External Sensor Array (Generation 2)AN/PSD-890 HESA
The HESA (Gen 2) focuses on short range organic support of existing vision systems, providing a pair of eye tracking active infra-red cameras. These short range cameras can illuminate cold and hot areas in a active scan, processing them through the onboard CPU and feeding the information in a HUD overlay in the helmet. These allows SPARTAN hunter-killer teams to track stealth units or enemies in foliage or track absconding units. The thermal camera can track targets by their specific heat distribution and make up. It is capable of tracking any sort of heat distortion, filtering known heat patterns of a variety of catalogued species, and contributing to the masking of the user's own heat signature. With the proper adjustments, the HESA (Gen 2) can track a single individual based on their personal heat signature.

Hardened External Sensor Array (Generation 3)AN/PSD-891 HESA
The HESA (Gen 3) focuses on short range anti-infantry and acoustic identification system designed to aid the user in hunting specific targets. The anti-infantry sensor can detect heart beats in the vicinity through passively scanning for the characteristic ultra-low-frequency electric field related to a beating heart to identify and track heart rhythms in the immediate vicinity then report back to the user's HUD on the species, heart rate, status and approximate size and strength details of the target. Though it has a short range, it is undetectable and is very difficult to jam due to on board filters. The passive SONAR sensor passively scans the background noise it receives and interprets this, looking for distinctive noises that match known signals stored in the internal database, such as engine noise, gunfire, enemy speech, with ranging, translation and analysis. It can track movement of infantry, with it being capable of detecting possible species and weight, detect the sound of engine noises and even analysis of damage dealt to the engine by combat or wear and tear.

Hardened Uplink/Remote Sensor PackageAN/PSQ-709 HU/RS
The HU/RS carries a telescopic camera with expanded zoom capabilities over average MJOLNIR with night vision and thermal vision filters allowing singular phase or hybrid detection at long range. This is generally a standard-issue helmet modification issued to rank-and-file Spartans on operations requiring higher-powered imaging filters than the ones already standard in Mark VII helmets or sniper spotters. Built into it is a Hardened Uplink allowing immediate uploads of image and video to the War Net. It is capable of tracking any sort of heat distortion, filtering known heat patterns of a variety of catalogued species, and contributing to the masking of the user's own heat signature. With the proper adjustments, the HU/RS can track a single individual based on their personal heat signature.

Blast Shield
As every veteran SPARTAN knows, the most vulnerable part of their armour is their face plate. Many SPARTANs can attest to this with their numerous facial scars. This extension uses a pair of full-colour optical and night-vision cameras to provide clear vision. It hinges down over the visor and is linked wirelessly or through a hardline to the user. Generally, this modifier is issued to units vulnerable to sniper engagements, operating in close assault, or operating in environments with high amounts of explosive ordnance. It increases survivability of potentially lethal faceplate hits by about 88%, making it a popular request. It is made of a composite AEGIS plate, backed onto a non-newtonian shock plate in a titanium shell.

Wrist Docking Port
Optional wrist mounted docking port allowing addition of electronic or combat systems to increase combat efficiency. Systems included are
 * Universal Global Positioning SystemAN/PSN-98 UGPS
 * The SRT Universal Global Positioning System is a ruggedised computer system that attaches to the user's wrist dock and displays a composite image generated from multiple orbital assets, generating a composite image. This can be used through either touch screen direction or neural uplink connection to designate targets or preform simple orbital reconnaissance or navigation. The UGPS can also be linked to other assets, such as weapons, allowing Snipers to preform long range kills through cover. The System can be preloaded with three detailed planetary maps, filled with information on local facilities, street names, directional data and updated on local servers every six days. The system can link with existing civilian or military assets, including GPS, ship board assets or aerial recon, allowing it to display live orbital feeds in a variety of spectrums or up to date maps for tracking and engagement of mobile enemy forces.


 * MC6 Individual Data/Net TerminalAN/PYQ-99 TACPAD
 * The MC6 TACPAD system that allows the monitoring of the flow of battlefield information and battlefield assets gathered by friendly units, including stationary sensors, infantry mounted sensors and UAV assets. The TACPAD can then be used to upload and view mission assets and parameters, allowing constant field updates of mission objectives. From here, the TACPAD can be used to directly interface with War Net assets and control the flow of information down to subordinate units.


 * Ammunition Bandoleer
 * Ammunition bandoleers allow SPARTANS to carry a small amount of additional munition to aid in operations. These have a number of variants for different situations.
