Warrant officer (WO) is a rank or category of ranks in the armed forces of many countries. Depending on the country, service, or historical context, warrant officers are sometimes classified as the most junior of the commissioned officer ranks, the most senior of the non-commissioned officer (NCO) ranks, or in a separate category of their own. Warrant officer ranks are especially prominent in the militaries of Commonwealth nations and the United States.
Regimental sergeant major (RSM) is an appointment that may be held by a warrant officer (WO) in the British Army, the Royal Marines, and the armies of many other Commonwealth and former Commonwealth nations. It is also an actual rank in the Irish Defence Forces, and formerly in the British Army, Royal Marines and United States Army. Only one warrant officer holds the appointment of RSM in any regiment or battalion, making them the senior warrant officer; in a unit with more than one top-ranked WO, the RSM is considered to be first amongst equals". The RSM is primarily responsible for assisting their commander in maintaining standards and discipline amongst the non-commissioned members and acts as a parental figure to their subordinates, sometimes referred to by the mantra "Drill, Dress and Discipline".
A non-commissioned officer (NCO) is a military officer who does not hold a commission. Non-commissioned officers usually earn their position of authority by promotion through the enlisted ranks.

The company sergeant major (CSM) is the senior non-commissioned soldier of a company in the armies of many Commonwealth countries, responsible for administration, standards and discipline.

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.
