I'd bet at least one person who helped come up with the name "Ultra Safe Nuclear Technologies" "UNSC" name had played Halo before.
...isn't it USNT (not USNC)?
I've never played Halo though so I just assume I'm missing something.
EDIT: I was just referring to the abbreviation for what GP said, "U"nited "S"tates "N"uclear "T"echnologies
