How many SGM/CSM's have served as an OC or OC/T at any of the Combat Training Centers during your career?

I served as an O/C from 2000-2002 and was selected for MSG while there. Now, I also attained my bachelor's and was inducted into SAMA while there also. But, O/C duty was listed on the proponent packet at the time, so I have to think it helped. Nowadays there is no packet, only the 600-25, so, it would need to be in there for it to carry the maximum weight.

I served as an OC/T when I was a SSG at the JRTC. Back then (Dec 97-May 01) it was no different than your experience now, a very rewarding assignment for me personally and professionally. I cannot imagine what my career would have been like had I not been afforded that opportunity. I learned so much from every unit that rotated through and I learned doctrine well above my rank as well. I felt that not only were the rotational units better prepared for their wartime mission, but I was better prepared to return to a deployable unit and lead Soldiers again.
I also have not sat on a Centralized Promotion Board but would welcome the opportunity. I think that I would be better set up for preparing my NCOs to compete at that level. Until you have the done it all you can do is speculate as to how to prepare and what the panel members look for, based off others experiences.

Being retired, never served on one of these boards, but I'm guess it is an assignment like any other. I believe each assignment has it's advantages and increases our knowledge. Case in point: As a SGM, I was the NCOIC of the USNSE and all U.S. forces assigned to NATO HQ at the time in Pristina. This allowed me to cross over with all services and our allies. I obtained experience and knowledge from this assignment I'd get no where else, and that knowledge did come in handy in my later assignments. I think more weight would be put into how one handles the assignment and grows from it.
