I was never a fighter. I think I got in two altercations at Fort Knox. One dude got mad he had to run a hill because he was holding a hot weapon and shot a round through the truck bed with 11 others sitting back there when we were shooting from a moving vehicle. He body slammed the closest person, well that was me

Grabbed his flak vest and he got to roll down the hill the next time. Drill Sergeants turned their back, we were taught "If a Drill Sergeant didn't see it then it never happened" haha.
Second time some dude got mad because he had to stand fireguard for 5 hours one night (because he fell asleep on guard the night before), meaning he only got 2 hours of sleep. I was the guy before his shift and he tried to take anger out on me. Drill Sergeants told the guy he was lucky I hit the window instead of him. I destroyed a double paned window in the barracks. Granted I had to pay $250 for the window, but everyone chose someone else when they got mad after that.
I'm more of a mellow guy, just rather relax and avoid any fighting or arguing.
