[QUOTE I had a SSG in my unit who had pilot wings. He was a Vietnam F-4 pilot. He came back in to get his 20 then retire.[/QUOTE]

Had at least a dozen of these types in my Squadron 79-85...
Former F-4, F-100 and 0-2 pilots. A few WSOs/navs as well (F-4s, C-119s, 121s, 133s, 124s), all trying to get 20...
There were a few also working in CBPO trying to get 20...
Also in the sq was the BAT 21 guy (no one knew at the time) as well as the co-pilot from the C-5 crash during Operation Baby Lift.

It was interesting when we gathered in "blues" for a parade. Yes, i said parade...
Oh, the uniform combinations... Still had guys trying to get away with some version of 1505s...
