The United States Air Force (USAF) employs a structured rank system for its enlisted personnel, starting from the lowest rank of Airman Basic (E-1) to the highest enlisted position of Chief Master Sergeant of the Air Force. Each rank comes with specific responsibilities and expectations as outlined in USAF Handbook 36-2618.
Airman Basic is the entry-level rank for both male and female enlistees who are undergoing basic training or apprenticeship. This rank does not have an insignia, and according to FederalPay.org, earns $2,017 per month. An Airman (E-2), a step above Airman Basic, includes those who have completed basic training and are receiving specialty training.
An Airman First Class (E-3) is expected to be ready for service in their first year and begin developing leadership skills. Senior Airmen (E-4) must demonstrate proficiency in leadership and technical abilities while attending Airman Leadership School.
