For the uninitiated, AFSC = Air Force Specialty Code, which (back then) was a 4-digit designator for one's career field. In the USAF, there were two distinct career fields primarily composed of guys who had flunked out of tech school. Anybody who has been in or around the USAF knows which ones (AFSCs) of which I refer.

Needless to say, the silence is deafening.
