JJ is (or at least was) correct. When I was still in, I was a In Airfield Management, in the same category (sort of) as Air Traffic Controllers and Combat controllers.

Ok just did some Googlefu and came up with this for the Air Force.

1C - Command and Control Systems Operations

1C0X2 - Aviation Resource Management
1C1X1 - Air Traffic Control
1C2X1 - Combat Control
1C3X1 - Command Post
1C4X1 - Tactical Air Control Party (TACP)
1C5X1 - Command & Control Battle Management Ops (1C5X1D Weapons Director)

1C6X1 - Space Systems Operations
1C7X1 - Airfield Management

So by this NEW set of numbers I would have been a 1C771

1 - Operations
C - Command and Control Systems
7 - Airfield management
7 - Craftsman (Airmen with many years of experience in the specialty, responsible for supervision and training)(one step below Superintendent)
1 - Base Operations
I Guess? <img src="/ubbthreads/images/graemlins/confused.gif" alt="" />

Anyway, My OLD AFSC (Air Force Specialty Code) was 27171.
