(For other countries which use this rank, see air vice-marshal.) Air vice-marshal (abbreviated as AVM) is the third highest active rank of the Royal Australian Air Force and was created as a direct equivalent of the British Royal Air Force rank of air vice-marshal. It is also considered a two-star rank. The Australian Air Corps adopted the RAF rank system on 9 November 1920 and this usage was continued by its successor, the Royal Australian Air Force. The insignia is one light blue band (on a slightly wider black band) over a light blue band on a black broad band.
