When I got to my squadron at Eglin in 1970 we had a Chief Master Sgt who was the go to guy for everything. He was a WWII, and Korean War vet and was just back from his 3rd or 4th tour in SEA when I arrived on base.
Without a doubt he was one of the coolest, most totally together guys I ever served with. He sort of took me under his wing when I arrived, and kept me on the straight and narrow. Did I mention he was a full-blooded Ogalala Sioux?
So one day the Squadron Commander (my GIB) comes in the ready room and tells us all that the Chief is retiring and we all need to report in full dress uniforms tomorrow. NO EXCEPTIONS. As if anyone would bail on the Chief.
The next day the entire Wing is out on the flight line in the hot Florida sun, marching in review for the Chief who is standing there dressed in his finest with more medals than a North Korean General, and wearing the rank of Brigadier General. we are all gob-smacked! After we are done parading, the Secretary of the Air Force pins another medal on him and announces that the chief has been reinstated to the highest permanent rank he was entitled to hold, and retired with full rights and privileges etc, etc.
It turns out the Chief enlisted in Canada in 1939, flew Spitfires and Hurricanes, until the U.S. entered the war. He then went into the Army Air Corps and flew P-38's and P-51s, 2 tours in Europe and one in the Pacific. He was an Ace and a Lt Col by the end of WWII.
When the war ended, racism reared it's ugly head. Someone in the Pentagon didn't like native Americans and he was told if he wanted to stay in the military he had to accept a reduction in grade to Tech Sgt. So he did.
The legendary Chappie James (our former Wing Commander) went to Washington, and went to bat for the Chief and he got him the recognition he deserved. No one in the entire Wing knew anything about any of this. The Chief never, ever talked about it.
There was one hell of an epic blow out in the squadron hanger afterward, I can tell you.
The next day our "Chief Brigadier" found me hanging out in the Nav/Radio/ECM shop ( I used to shameless bribe the enlisted guys, because I was one for my first year in the Air Force). He gave me a pair of his wings "for luck".
They must have worked, because I'm here to tell the tale.
