Show us the demographics.
I suspect unqualified blacks and trannies made up all of them.
Prince-Senior Master Sargents are 2% of enlisted men. CMS’s are 1%. That means there’s a lot of weeding-out to get there. Most will put in a lot more than the 20 years as the job gets easier. Lower enlisteds are scared of them. They get more distant as they move up as they think of themselves as royalty.
