Man, I don't get it. Infantry has pretty much been a "hold this heavy ass shit, walk long distances, kill enemies before they kill you."

And somehow militaries for thousands of years have been able to convince huge groups of young men to either sign up for this or because they were told "or else."

And I guess "or else" is usually starvation, conscription, or execution. At any point a group being trained could say "yo guys this is stupid" everyone else would probably agree, and then the entire army thing would ... Stop. wouldn't it?
