M366 Demolition Charge

"A blast pack is good for demolishing a building. a Demo Charge is good for demolishing a city block."

- Warrant Officer Kyle Falman

is a UNSC explosive charge, designed for heavy duty demolition against hardened targets.

Uses
The M366 Demo Charge is used by combat engineers as a heavy duty demolition system, preferably for controlled destruction of a structure or stationary target. The charge can be used in concert with a number of explosives to provide wide ranging destruction, such as levelling a large building, a bridge or in sufficient amounts, scuttling or crippling a warship.

Operation
The M366 Demo Charge consists of two components, the detonator and the charge. Each charge consists of two 50x20x20 shock resistant thermoplastic containers, stuffed with C-14 Plastic Explosive. These are linked together and have pre-installed detonator insert points. These are carried together as one charge, which has the facilities for being connected by fibre-optic cable to the detonator or radio signalling. As a protective measure, should the charge be rendered null by an electromagnetic pulse, it will release a spring loaded explosive detonator, exploding the charge regardless. This charge is buried under the primary fire control, which in itself has been rendered tamper proof and booby trapped. This has four inserts of fibre-optic cables with the option of inserting 'delay' blocks to delay the explosive by a dial control for controlled explosions. It has a jam resistant radio receiver and a million digit string arming code that jumps at regular intervals.

The detonator component clips on to any existing demo charge bundle. It consists of a radio antennae, six slots for fibreoptic detonators and the detonator control. The detonator consists of a arming computer, allowing the user to set a four string code for detonation. The detonator is then armed by a manual control, where the thumb control must be depressed, then turned from 'safe' to 'armed'. At this point, it and all linked explosives are armed and ready to detonate. From here, it can be detonated remotely by a slaved universal explosive detonator for detonation. The detonator itself is booby trapped and tamper resistant, and should the other explosives be cut off from the fibre-optic lead of the detonator or the radio signal while armed, it switches to a ten second countdown unless it is reconnected.
