What is the abbreviation for an Air Force General?

The abbreviation "Gen" is commonly used to denote a General in the Air Force, as well as in other branches of the military. This term is a standard military rank designation and signifies a four-star General, which is the highest rank typically achieved in the Air Force.

Other choices refer to specific ranks or include additional context that doesn't align with the general abbreviation. For instance, "AF Gen" is less standard and not as widely recognized as simply "Gen." "Maj Gen" stands for Major General, which is a two-star rank, and "Brig Gen" stands for Brigadier General, a one-star rank. Both of these are specific ranks and not overall terms for a General. Therefore, the abbreviation "Gen" accurately captures the rank of a General without further specification.
