Depends on the day. In the first few weeks they drop you all the time. When practicing formation, marching, etc., you get dropped more. When you are in the classroom not quite as frequent. On range days, not so frequent. Those are closer to the end though. Been 21yrs since I was there. Could be different. Every basic station is a little different. Ft Jackson is where I did my AIT. The basic soldiers from Ft Jackson were handheld it seems as compared to what we saw at Ft Leonard Wood. Majority of my basic class were combat engineers. About half a dozen of us mechanics, and 2 or 3 medics were thrown in with the 12B's. Sucked, but I am glad I had it there. Made me appreciate AIT more.
maybe I should add, you do PT every day. Getting dropped or getting smoked is what I was referring to. Some days felt like PT all day. Lol
