"Roughly 8,400 active duty servicemembers have been removed for refusing vaccine orders, according to the latest DOD data shared with the DCNF. The Army tallied a 97% vaccination rate as of Dec. 16, but roughly 9,000 soldiers remain unvaccinated."
If it is the same across all services as it was in the Army, only 3% are willing to try to dodge the clot shot. This 3% wouldn't be enough to help in a balkanization scenario. You'd need whole National Guard units to pledge allegiance to your new cause; 3%, even if it was the leaders (it wasn't, they pushed this nonsense) won't be enough to coalesce into a new fighting force.

That newly commissioned officer you're referring too, was mustered out after the controversy from his photos. West Point, though, has gone mostly woke, but that's another thread. I would rather have a mustang officer, or OCS grad, than some service academy ring knocker, in charge. This has always been the case though.
Brit military is worse than the American for wokeness. And yea, there are dirtbags at all paygrades.
