It is a singular appointment – it is only held by one person at any time.

The special insignia for the RSM-A is the Australian coat of arms with a wreath around it.

The twelfth and current Regimental Sergeant Major of the Army is Kim Felmingham.

The appointment is the equivalent of the Warrant Officer of the Navy (WO-N) in the Royal Australian Navy, and the Warrant Officer of the Air Force (WOFF-AF) in the Royal Australian Air Force.

The post was created by the then Chief of Army, Lieutenant General Sir Phillip Bennett.
