The following terms come from an educational handout issued during World War II at a Naval Reserve Officer Indoctrination School at the US Naval Air Station in Jacksonville, Florida. These Naval Reserve officers were classified as A-V(S), and were members of the Volunteer Reserve (Special Service). A-V(S) officers were aviation officers, commissioned or warrant, including gunners, radio electricians, machinists, aerographers, and photographers, qualified for specialist duties. The only editorial change to the text has been the alphabetization of definitions for the convenience of readers.
