Airman First Class. A:1C

**Airman First Class (A1C)** is a junior enlisted rank in the United States Air Force, designated as E-3 in the pay grade system. The rank was established in 1952 following the creation of the Air Force as a separate branch in 1947, replacing the earlier Army Air Forces ranks. Airmen First Class are typically responsible for carrying out technical tasks, supporting mission operations, and furthering their professional training. The rank insignia features two chevrons, and airmen usually advance to A1C after completing basic training and technical school, serving as a key foundation for future non-commissioned officer leadership.
