No, I don't recall it being THAT kind of fun...

you sure not dare laugh watching the guy in front of you duck running naked in front of you....

This was in Feb 1990 when I attended boot camp at Great Lakes, even after the usual "walk the line of shots" in both arms, a few days later they took us to another huge room, had everyone line the walls, they had everyone face the wall and drop your draws, hands on the wall looking away from the corpman and the cart full of injection syringes that looked like they were from a time long ago, they had the loops for your two fingers and thumb and were made of stainless steel, needle was Long and LARGE, they gave us 1 HUGE stainless syringes full of Amoxicillin I believe, I would have to find my shot record to confirm that, once you got that shot in your cheek you had to roll around on the golf ball size knot in your arse for 15 minutes working it into your tissue, and then we began a 4 hour march,,,,, the next morning guys that were on the top bunks that jumped down to the deck would collapse when they tried to put weight on that leg from being so sore.... maybe someone in the class had something that they didn't want everyone else to catch ?
