The UNSC C-12 Shaped-charges or C-12 SCs are used mainly for heavy demolitions and can also be used as weapons. This compound is extremely dangerous and very volatile. A small 4x4x4 inch cube alone can level a five story building. It's solid, but malleable enough where it can be shaped or bent into different forms to stick to surfaces better and is detonated with electro-shock detonator sticks or remote detonators.
C-12 is also hefted in medium sized backpacks called "Damage Packs" or "Blow Packs". Two Damage Packs contain enough C-12 to blow through three meters of UNSC standard armor plating.[1]
During the first assault of the rebels on the Erandinus System, which happened to be the Spartan's first real mission, Sam hefted two medium-sized backpacks full of these. After capturing the leader, Watts, Sam used these to blow clean through the base. However, in doing so, he also murdered uncountable "civilians", or non-soldier sympathizers.[2]
Trivia
- During World War II there was a reasonably powerful explosive called C-2, which is a precursor to the present day C-4 and possibly to C-12.
