You may be correct I can only speak from experience. I enlisted in 1965, did two tours in VN, Army, I think that I might have a different opinion,
You were a warrior in the real war and I am in awe of your sacrifice for the rest of US. My lottery number was 215 and I went in with only two months left of the Vietnam era. You know, I was Air Force where generally those that go to war are officers and we enlisted guys worked back at the base. That may have made a difference too.
In six years in service I never had any tear gas training or had any mine field training. In Basic we had one class about the Code of Conduct, one class about the UCMJ, one class about how to recognize rank, one class about first aid, one class about bearing and behavior, etc. We marched together, but we had absolutely no combat or fighting training at all.
Think back to when you completed Basic Training. How prepared do you think you were for the rest of your military experience?
When Trump said “more training militarily than a lot of the guys that go into the military”, I noted that he didn't say most guys or half the guys, he just said a lot of guys.
