ITAR basically sets the restrictions for who can use things that are on the Munitions List. That includes rockets, satellites, sensitive data etc. That's in addition to the usual missiles and bombs and whatnot.

I know in WW2 they tested pigeons and chickens. It really doesn't put you in an esteemed class if you're classified as a missile pilot; I mean astronauts had chimps, that's cool. Chickens? Not so much.
