Regimental Sergeant Major

Regimental Sergeant Major (RSM) is an appointment held by warrant officers class 1 (WO1) in the British Army, the British Royal Marines and in the armies of many Commonwealth nations, including Australia and New Zealand; and by chief warrant officers (CWO) in the Canadian Forces. Only one WO1/CWO holds the appointment of RSM in a regiment or battalion, making him the senior warrant officer; in a unit with more than one WO1, the RSM is considered to be "first amongst equals". The RSM is primarily responsible for maintaining standards and discipline and acts as a father figure to his subordinates.
