after my first deployment we had one guy test positive for cocaine. he was out within a month. a different soldier had more than 3 dui's and never got kicked out. he was too good at his job. we had another guy who we all swore was juicing, and he never got kicked out. that guy had like 5% body fat, weighed like 275 and was like 5'10".
as far as PC goes, my platoon didn't care. if you weren't tough enough to hang, you got pushed out of the way. my unit was an attack helicopter battalion, and we loaded the ammo on the helicopter, so you could kind of say we could get away with a lot. there was one occasion where some of the guys duck taped one individual, tied him to a chair, and pushed him around the hangar for everyone too see, well it turned out that individual's dad was a general, and everyone involved got a letter of reprimand in their files. he wasn't the first or last person to get duck taped and pushed around the hanger like a war trophy, just the first one who didn't have skin thick enough to handle it. that dude ended up leaving shortly after.
my first deployment we were stationed at Bagram and lived next to some active duty retards. this was back in 2004, and even then there were pussies in the military. I remember one mortar attack where the active duty guys were being yelled at by their boss to "move move move, get in the bunker, hurry hurry hurry." we hadn't even felt any mortars hit or seen any incoming. it was pathetic how he overreacted to such a degree. the base at Bagram was huge and 90% of the time we didn't know we were being attacked, except that the giant voice system announced it. one of the few times we did know we were attacked was when an rpg or whatever it was hit a conex about 200 yards from our housing area. it blew a big hole in the conex and one lucky random guy walking by got hit by shrapnel. the really lucky part was that the conex was on one side of a hesco barrior, and on the other side was the flight line with the runway, and about 15 hemmits that were used to store JP8. there would have been a hell of a firestorm if it had hit about 10 feet in the other direction.
