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 in seconds. It's solid, but malleable enough where it can be shaped or bent into different forms to stick to surfaces better and fit into tight spots and is detonated with electric-shock detonator sticks or remote detonators.
- If enough C-12 is provided, it is able to penetrate Titanium-A armor, the armor that is commonly mounted on UNSC warships.
