C-7 foaming explosive

C-7 foaming explosive is a highly explosive compound that is used in demolitions by UNSC forces. It is comprised of various chemicals that react to a signal electrical current shock sent through a detonation switch. It is liquid in vacuum, but once contact with a hard surface and oxygen occurs, it becomes a foaming, semi-solid adhesive resin.^[1]

Uses[edit]

Its most notable use is when Corporal Locklear used it to destroy the Forerunner Crystal (the reason why the Covenant were chasing them), leading to his death.^[2]

Trivia[edit]

C-4 is short for "Composition 4", therefore it is likely that C-7 means "Composition 7." It is also likely that it is simply a codename based on the order in which it was developed, not an indicator of its explosive power.
