Command Sergeant Majors...fine idea, but poorly executed. In my 24 years as an officer I can count on one hand the CSMs that fit the ideal and contributed to unit readiness. Those 5 were the real deal, and took care of soldiers. One of those 5 became Sergeant Major of the Army. The scores of others were glorified horse holders and butt kissers interested in only their benefits and careers. They were a hinderance rather than a help.
He rode my ass my senior year, because I opted not to go to Airborne School after ROTC Summer Camp. It was a financial choice, as I made no money during summer, and I would have had to pay full freight to attend.
LOL, I flew back to Spokane after getting my wings, just to prove to him I did it.
Our CSM in Germany was a professional, low key, noncom. He was a great source for advice. I also had an infantry First Sergeant at the ADA battery I was assigned to, before getting kicked up to Bn HQ.
He was awesome, 3 tours in Nam as a First Sergeant. We worked together very well. When we underwent our ARTEP, he comes up to me, "Sir, what the hell am I supposed to do? I don't know anything about ADA." I laughed, "Top, you know how to set up a CP? That's it...just keep doing your job."
Our problem was our Battery Commander was a great staff officer who never should have been allowed near soldiers...and I'll leave it at that.
