I can personally vouch for this. I saw it during my time in the military, and I saw it at the base I worked at until my retirement last year. Granted, yes, there are still many officers who are very principled and have integrity, but they are getting fewer and fewer in numbers.
I retired in ‘98 - and that was the beginning of the end where it was becoming political suicide for commanders to take care of heir people - hey rose higher and faster by being willing to sacrifice the men and women that elevated them to their positions - they cried, “RHIP” - during my retirement talk - I reminded them that R also HIR - “hath it’s Responsibilities” and opined that two many of them have forgotten that.
