Is there no rank among airmen?

Answer 1

In the US Air Force, "Airman" is a rank (E-2); there are also other ranks with the word "Airman" in them, such as "Airman Basic" (E-1, lower), Airman First Class (E-3, higher) and Senior Airman (E-4, higher still). All four of these ranks are collectively considered the "Airman" ranks. The enlisted ranks above Senior Airman are non-commissioned officer (E-5 and E-6) or senior non-commissioned officer (E-7 through E-9) ranks.
