Australian Army enlisted rank insignia

Like the British Army, the Australian Army does not use the term 'enlisted' to describe its non-commissioned ranks. Instead, personnel who are not commissioned officers are referred to as other ranks. These are soldiers, non-commissioned officers (NCOs) and warrant officers (WOs). Warrant officers are appointed by a warrant which is signed by the Chief of the Army. The insignia for non-commissioned ranks are identical to the British Army up to the rank of warrant officer class two. Since 1976, WO1s and the WO in the Australian Army wear insignia using the Australian Coat of Arms.

Warrant officer appointments and special insignia
There are a number of appointments held by the senior warrant officers in the Australian Army. These are appointments, not ranks. In general, the rank of the incumbents of these positions is WO1, and they wear the WO1 rank insignia. Due to it having its own special insignia which is worn instead of the WO1 rank insignia, the Regimental Sergeant Major of the Army (RSM-A) is unusual as it holds the unique Army rank of Warrant Officer (WO), which is senior to WO1 and equivalents.

Other appointments include:
 * Academy Sergeant Major (ASM): One WO1 is appointed every 3 to 4 years to serve at the Australian Defence Force Academy as the ASM, the position is rotated between the Royal Australian Navy, Australian Army, and the Royal Australian Air Force.

Unit level appointments:
 * Regimental sergeant major (RSM): The senior soldier in a regiment/battalion sized unit. Known as the RSM, even in units designated as battalions. RSMs hold the rank of WO1.
 * Company/squadron/battery sergeant major (CSM/SSM/BSM): The senior soldier in a company/squadron/battery sized sub-unit. Holds the rank WO2.
 * Artificer sergeant major (ASM): The senior soldier in a RAEME unit. Can be a WO1 or WO2.
