That's funny Blitz, your comment that "if you can't touch 'em, you can't teach 'em" was the point of my pops' rant tonight. He basically said, you're going off to war, and against an enemy that will do anything to defeat you -- you probably need to be okay with some drill instructors beating your *** to help deal with the real beating that's likely going to come to you.
When I was younger, I was infatuated with Vietnam war movies and I didn't have any real idea about my father's own experience of it, so I always got silence as well. But when I finally came around and understood more, he came around too and shared some stories. Many that are heartbreaking I'll never forget. Anyways, pretty terrible time for our servicemen and women and the country in general.
