Listened to a Podcast interviewing one of the Red Eagles recently, he talked about his journey to get there and how the only dedicated air-to-air F-4E units in the USAF after Vietnam were the 36th TFS out of Osan in Korea and the 57th FIS out of Keflavik in Iceland. He made his way to the 36th in order boost his chances of an aggressor squadron posting. On a side note when I was researching the 'Hill Grey' scheme for the 36th I learnt there was an initial 3-tone grey 'Hill Grey 1' scheme used on the first F-4E to be repainted. It was closer to the original 3-tone grey scheme on the F-16A with all light grey undersides (and drop tanks), it only really appeared on US F-4E Phantoms in Korea.
