Soldiers were literally chosen based on a lottery
If your name happened to be called on a particular day then you were literally forced to participate in a war and potentially die when you didn't even ask
Thus, the army became filled with soldiers who didn't want to be there and didn't want to fight, so of course there was going to be protests. The whole draft system was fucking retarded since day 1 and anyone with a brain could've seen this coming. Thankfully Nixon gutted the draft system and we moved onto a volunteer force, which allowed the army to at least be filled with sociopathic killers that at least want to be there and are more willing to fight.
