When I was in boot camp at Parris Island, about 5 or 6 months ago, we learned really well how to shoot, but the PMI's (primary marksmanship instructors) don't go heavily into ballistics. They mainly focus on getting in a good shooting position (standing, kneeling and prone) and on proper sight alignment. You learn how to adjust for windage, and different ranges. We shoot from 200, 300 and 500 yards. I honestly don't remember talking much about ballisitics, but they sure are good at teaching how to put a 5.56 round at center mass from 500 yards away. I guess they don't really need to go into ballistics much. I don't know much about the Marine's scout sniper school, but I'd be willing to bet those guys learn a lot about ballistics.

Also, at the school of infantry (on the basic level) you don't really learn about ballistics either. I'm not an 0311 (rifleman) I'm an 0351 (blow stuff up) but I don't the 11's would have learned anything about ballistics. There are lots of advanced courses, so who knows.
