Notes & Sources
- 3D1X3 RF Transmission Systems is a retired identifier: the conversion instructions embedded in the AFECD 30 Apr 23 delete the AFSC effective 30 Apr 23 and convert all holders to 1D7X1Q in the cyber defense operations family.
- The in-force directory carries no section for this code; the successor 1D7 family specialties (Warfighter Communications, Information Technology Systems, Radio Frequency Transmissions and Electromagnetic Activities, Cable and Antenna, Data Engineering) describe the current functions, so the old code alone does not establish current duties.
