I remember that bicillin shot very well.
I was standing barracks guard duty and they sent back someone to relieve me. I humped over to Medical and as soon as I got there, I dropped my drawers and they injected that thick instant fire into me. I had a top bunk and the next morning when I jumped out my leg gave out and I hit the deck. I definitely hobbled for a day or two.
Our company was the first our CC led in 10 yrs. His goal was for no one to be left behind. We had a whole bunch of recruits that had GCT/ARI scores down into the twenties. I was one of only a single handful that had scores in the 70's. So we were the ones that held all the watches. All the night watches so all the rest could get a good nite sleep. All the day watches so they wouldn't miss any training sessions. I would even hold evening group discussions over what went over in training that I didn't even go to. Our Company and our Sister Co were tied for the bottom in competitions. I received no firearms training, but had to qualify. So they sent a recruit back to the barracks to relieve me. I humped to the range. They handed me a rifle and I was still breathing hard. And Damn, I let one shot drift out to the 9 ring. If I could of hit all ten in the bull I would have gotten a weekend pass. Such was my experience in boot camp. Our CC was able to not leave any recruit behind. We even were able to pick up a recruit that had been in boot camp for 10 months or so. He had been left back so many times. He graduated with us as well.
