Regimental Sergeant Major

The Regimental Sergeant Major or RSM is the senior Warrant Officer Class One in a British Regiment, and is primarily responsible for maintaining standards and discipline. The same rank exists in the Australian and New Zealand armies. In the Canadian Armed Forces, RSMs have the rank of Chief Warrant Officer. All warrant officers in the British Armed Forces are addressed as 'Sir' by their subordinates, but, due to their non-commissioned status, are not entitled to a salute. They are however issued with a warrant on appointment.
