'''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 of Nations|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 [[Primus inter pares|first amongst equals]]".{{citation needed|date=November 2020}} 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".{{citation needed|date=November 2020}}
