Input: Text: edit: to all the civilians who have never been in the army, this wasn't physical abuse.  i know it sounds bad, but the most pain i felt from this was him lifting me off the ground.  he did not knock the wind out of me, that came from me hitting my plates in my kevlar, and his kick was just a nudge in my side to get me off the range.  everyone was laughing.  he did not beat me up.  

edit: i was excited to fire my first machine gun! 

so the day of training where we got to fire the m249 was the time i was physically rocked by a drill sergeant during my boot camp.  i was holding my 100 rounds, excited to fire a fully automatic machine gun for the first time in my life.  

i was ordered to place my rounds next to my m249 and to get into the prone.  once ordered to feed the belt into the weapon by the tower, i remembered the very important tip of "brass to grass" to make sure the brass links connecting the rounds together was on the bottom and not on the top.  as i was focusing on this, i wasn't paying attention to the direction the bullets were facing, and i was about to press the latch down when i hear a thunderous yell.

"what the fuck are you fucking doing!? are you fucking kidding me!?" 

i felt a really sharp boot heel press into my back and a knee go into my spine and he grabs the latch.

"look at your fucking rounds you fuck tard! look!"  sure enough, the rounds were facing me, i had fed the wrong end in, making the brass on the bottom and the rounds facing towards myself.  apparently this was the first time this drill sergeant had seen such stupidity because he called out, "hey drill sergeant ****, look at this.  look at what this bitch shit just did."  

"no fucking way."

i knew the next few minutes were about to be full of some intense pain and humiliation as he ripped the belt out, took his knee out of my back, and i could feel his fingers wrap around the bottom of my ach, like he was holding up a fish he just caught.  

i way 210 pounds mind you, and am 6"3'.  he lifted me up by my ach so hard that my feet left the ground as he threw me flat on my back, smashing hard against the plates in my kevlar and knocking the wind out of me.  i thought i heard my spine crack, or at least it felt that way as i grasped for air, hearing faint laughter from privates and other sergeants alike.  

"get the fuck off my range before i fuck you up."  and with that, he gave me a swift kick into my hip as i rolled over, gasping for air, trying to crawl to some sort of safety before he continued to rock my shit.  

i got to fire a little bit later because the drill sergeants didn't know who i was in all honesty, and i could hear them talking a few days later about "a kid who fed the chain in backwards." so he didn't use my name so he didn't recognize me when i went up to try and fire again.  

that shit hurt, but firing that gun was the most fun i've had with pants on.  i loved basic.  i'd do it again, for free.  

thanks for reading guys.

TIFU by feeding the bullets into an M249 during basic training.
