There seemed to be two types of NCO back then political type, and war type, the war types liked me and the politicals didn’t.
One of the saddest things that I saw in the Army was in late 1973 when they started drumming out the officers as we shifted (instantly) into a peace time Army, it seemed like the best were the first to go, and the weakest got to stay, I didn’t know them or their records well of course, but my street instincts that were highly developed before I went in, were not happy up with the choices I was seeing, some of that peacetime transition really bothered me and the military of the later 1970s showed that I was reading it correctly.
That still happens today. Some of the worst are making rank, and the ones that instill Army values are sent packing.
