The enlisted class is the lower of the two groups, comprising all ranks from Airman Basic (E1) to Chief Master Sergeant of the Air Force. As a non-commissioned representative and leader of the enlisted ranks, the Chief Master sergeant of the Air Force has no grade code, but comes after the rank of Command Chief Master Sergeant, which has the grade code of E9.
The lowest of the officer ranks is Second Lieutenant (O1) and the highest is General (O10), or "Air Force Chief of Staff." During wartime, the highest rank becomes General of the Air Force, which has no grade code. It is the Air Force equivalent to the "General of the Army" and the Navy's "Fleet Admiral."
Unlike other military branches, the USAF has no warrant class of ranks.Learn more about Military
