The military loves cheeky shorthands and acronyms. They're really good at backronyms, too. It won't take long for them to come up with something like Bisox, oxaz, BIAX, BNT ("bomb, not TNT"), etc. Or maybe just the brand name of whoever is selling it.

C4 is just an RDX mixed in a stabilizing polymer putty (Semtex is the same with PETN added to the mix), the vast majority of explosives used these days are “PBX” or Polymer Bonded Explosives so the military will end up giving it some classification code which is easy to remember and write down on supply orders like C10 or w/e.
