The MA5D Individual Combat Weapon System (abbreviated MA5D ICWS), more commonly known as the MA5D Assault Rifle, is a United Nations Space Command fire-arm.

Description
The MA5D Assault Rifle is the fourth rifle in the MA5 Series of firearms manufactured by Misriah Armories. It is currently the standard rifle of the United Nations Space Command Marine Corps' Special Operations Divisions. The MA5D is a much more balanced weapon compared to its predecessor, the MA5C Assault Rifle and has received slight technical as well as major physical changes from the MA5C. The rifle was upgraded with an optional underslung 30mm grenade launcher or 12 guage shotgun.

Advantages

 * Optional fire modes
 * Underslung grenade launcher or shotgun
 * Lightweight
 * Stronger alloys

Disadvantages

 * Lack of heavy stock makes it front heavy
 * No flashlight
 * Grenade launcher/shotgun can only carry three rounds
 * No sights

Description And Appearance
The MA5D Assault Rifle is a burst/automatic UNSC rifle that fires 7.62mm x 51 FMJ (Full Metal Jacket) rounds. It fires from a 32-round magazine that is housed in a receiver that is just behind the firing mechanism for the underslung grenade launcher/shotgun.

This titanium alloy and polymer assault rifle firing with a gas-operated with a rotating-bolt and therefore must be cocked before the first shot can be fired. The charging handle used to chamber the round is situated on the right side of the gun, semi-hidden in the housing, and moves during operation. Once the first round is fired, the gases from that round and those to follow impinge upon a gas piston, which pushes back the bolt carrier, rotating the bolt inside and continuing to chamber rounds until the magazine is empty. Once the magazine is empty, the charging handle must both be pulled back and locked or, must be fully cycled after a fresh magazine is inserted to load the next round. The magazine release button is located above the magazine, on the right side of the weapon. The ejection port is located on the right side of the gun above the mag housing.

Ammunition
The MA5D uses 7.62x51mm (.308 caliber) armor-piercing full metal jacket rounds. Actual energy from this round is 2472 ft·lb force. This is quite high for a rifle cartridge, and the round has been historically noted for its power and range. "7.62mm" is the diameter of the bullet itself, which equates to .3 tenths of an inch, or .30 caliber. The "51mm" comes from the length of the brass casing containing the powder and primer. Often being associated with a considerable amount of recoil, the MA5C appears to be able to absorb it so the weapon remains steady even while holding down the trigger until the magazine has been exhausted.

Armour-piercing ammunition has a tip coated in a form of metal that allows it to punch through layers of soft and hard body armor, as well as light vehicle armor. The tip may is made from a variety of materials, including tungsten, tungsten carbide, titanium carbide, and hardened steel.

Armour-piercing rounds have the obvious advantage of being able to deal with protected targets, but they release less energy to flesh because they tend to just slip through a targets body, and not dumping all of its energy into the target.
