Airman first class

Airman first class (A1C) is the third enlisted rank in the United States Air Force, just above airman and below senior airman. The rank of airman first class is considered a junior enlisted rank, with the non-commissioned officers and senior non-commissioned officers above it.

Airman first class is a rank that has also been used by the U.S. Navy and the U.S. Coast Guard, although it is not currently in use. In documents about the history of U.S. armed forces, this combination of pay grade and rate is abbreviated as "A1C".
