what year? What month? What platoon #? If you can't tell me, I call BS. You want to know why I call BS? Cause it is.
If a DI were to "publicly" kick the sh#t out of you, he'd be charged with assault. If someone died of "heart failure" in front of him and he was responsible for it, once again he'd be brought up on charges. Guess what, I've seen people get the sh#t kicked out of them in training....by other boots. I've seen men in sweats, raincoats and boots run with their rifle at port for MILES when they dropped their weapon or were needing some physical fitness encouragement. but this happened in private and out by the rifle range or off base..... I've heard of men falling off a deck of a ship by accident, heard of men in other platoons die of something... I never knew cause I didn't see the autopsy but it could have been heart failure, heart arrhythmia, potassium elevation, hypothermia, hyperthermia, dehydration etc.... gunshot, grenade accident, walking into tail rotors, falling out of buildings , falling off of ships, getting drunk and wrecking cars, getting in fights and on and on...
As for taking it from a 50 year old with a buzz cut. Brother you once again have no clue. Nothing personnel. Most of the ones I knew were in their mid 30's to early 40's. The Marine DIs in order to get to be a DI are usually the best, even if a few screw ups get through. We're talking about having high test scores, no discipline problems, no personnel problems and on and on. Their not trying to get you to join a group of guys to hang out, chase tail and drink beer (even though it happens). The DI is there to prepare you for war. To complete your assigned duty without excuse and basically to serve your country with honor. You are there to become a warrior ...... and a rifleman. period. It's a "fraternity" in the meaning of a bonding together for a common purpose. But a college frat and USMC are fraternities in that sense but most recruit platoons would have a very very hard time putting up with college frat boys if they were to meet up and say...."hey we're just like you, a fraternity"...hahahahahahaha.
I pretty sure my son won't be joining one unless he pays for it himself. I also don't think he'll join the other fraternity with the yellow footprints on the street.
My point was that these are two entirely different things. Being in a fraternity is a social club, whereas joining the military is something altogether different, as are the stakes. I'm sure Coast Guard OCS is quite a bit tougher than fraternity hazing too, and I'm sure the guys who've been through BUDs or the Fan Dance can tell stories that make Marine Boot Camp look like the Girl Scouts.
I'll just assume that the tough talking on your part is the Aggie side of you, and not the Marine. Most of the Marines I know don't go around bragging anonymously on the Internet, and the only times they've ever talked about their experience in the Crucible or other aspects of training or combat have come when I've asked them specifically about it.
