Militart use only? Well, that includes handguns, especially 1911s, M-16 assault rifles (real assault rifles, not what the press lies about), sniper rifles up to and including .50 BMG, silencer, sawed-off shotguns, and for that matter single-person-operable anti-tank and anti-aircraft missiles. Oh, and miniguns, and 20 mm grenade launchers (which just look so cute under the rifle barrel on an M-16). And probably a few others. Duck hunters would be pissed, there are no Krieghoffs in the military.
Or what the "press" is simply too stupid to know about
I'm looking around for a suitable clone of an M14 battle rifle, and there seem to be a lot of military rifles and semi civilian rifles that may fit the bill.
Can you imagine the blank stare you would get from a reporter if you used the term battle rifle when correctly referring to an M14 type weapon as opposed to an assault M16?
The M203 and M-79 grenade launchers are both chambered for 40mm rounds.
