You stupid sack of crap - what part of AIR FORCE do you not understand? How in the hell do you do a bayonet charge in an airplane?
Pull your head out of your land-bound butt and understand that not everyone in the military works on the ground. Sailors on boats don’t need to do hand-to-hand combat. The only time I would be exposed to hand-to-hand combat would be if I went down behind enemy lines - which I never did, and none of those who did that I’ve talked to ever needed to fight hand-to-hand either.
It will be a long time before UAVs can replace manned aircraft. If you don’t understand that, then you don’t understand enough to take part in an intelligent discussion.
