Since I had been colorblind since birth, I was first turned down by the Air Force,

Air Force?

[ExGeeEye]

Officially the US Army Air Forces from 1941-1947.

I think I would have referred to that mouthful as the Air Force, especially when speaking to a foreigner who would be likely most familiar with the present terminology.

(Dad was USAF 1958-1984; I was Army 1986-1999.)
