The Air Force is offering new special duty assignment pay to airmen in four specialties, the Air Force Personnel Center said Thursday.

The specialties added to the special duty list are military training leaders, airmen in the Guardian Angel Operations Test Program, Defense secretary and chairman of the joint chiefs of staff executive communications team members, and airmen assigned to a newly established Air Force Special Operations Command unit. Airmen in certain nuclear-related career fields have also been approved for special duty assignment pay.

"The purpose of these special pays is to incentivize airmen to volunteer for and perform duties in a particular career field, location and/or special assignment where the scope of responsibility and required skills exceed those of other airmen in the same career field and rank," director of force management policy Brig. Gen. Brian Kelly said in a news release.

The defense courier operations and airfield management career fields are being dropped from the list of jobs eligible to receive special pays. Airmen in those fields will continue to receive half of their original special pays for 12 more months, before the special pays are eliminated entirely.

Special pays will be adjusted for strategic debriefers; survival, evasion, resistance and escape airmen; enlisted weapons directors (certified and new); forward area refueling point personnel; test parachute program airmen; defense attache specialists; and first sergeants performing duties at the First Sergeant Academy. The release did not say how much those career fields' pays would change.

The Air Force was considering reducing special pay for military training instructors and recruiters earlier this year, but has decided not to change their pays.
