Air Officer Commanding (AOC) is a title given in the air forces of Commonwealth (and some other) nations to an air officer who holds a command appointment. Thus, an air vice marshal might be the AOC 38 Group. An air officer heading a particularly large or important command may be called a Air Officer Commanding-in-Chief (AOC-in-C). The equivalent term for army officers is General Officer Commanding (GOC).
Royal Air Force usage
In the RAF those air officers who command a group are styled Air Officer Commanding, followed by the name of the group. Currently, there are three AOCs:
United States Air Force usage
In the United States Air Force, the term Air Officer Commanding is used specifically to refer to the specially selected officers who command cadet squadrons and groups at the United States Air Force Academy in Colorado Springs, Colorado. In the case of a cadet squadron, the AOC is normally a major; in the case of a cadet group, the AOC is normally a lieutenant colonel. These officers exercise command authority over their cadet units and are expected to train cadets in officership and military matters, advise the cadets who hold leadership positions in the unit, and act as role models for the future officers. Although the vast majority of AOCs at the Academy are, logically, United States Air Force officers, a small number may come from the other U.S. military branches. While holding these positions at the Academy, these officers are still referred to as "Air Officers Commanding" despite their being Army, Navy or Marine officers.
