When I worked for the Army as a civilian we would get an occasional Colonel who wanted to turn everything upside down for his OER, not to actually improve anything. We had an expression, “I was here when you got here, I’ll be here when you are gone.” Everyone like that needs to go. If they need help replacing the folks sent packing they probably couldn’t do better than recruit right here.
Without the Army Civilians to provide long-term institutional memory, I don't think the Army would function well at all.
