Job Assignments (MOS)

Some of the Crew Positions and other Job Assignments of the men in our Rosters are identified by a number rather than a name. The numbers were called their Military Occupational Specialty, or MOS. Though there were hundreds of MOSs, the most common for Air Crews and Bombardment Groups are listed below.
