Regimental Sergeant Major (RSM) is an appointment held by Warrant Officers Class 1 (WO1) in the British Army, Royal Marines and many Commonwealth armies including the Australian Army and New Zealand Army, and by Chief Warrant Officers (CWO) in the Canadian Forces.

Canada

In the Canadian Forces, the appointment of Regimental Sergeant Major is normally held by an army Chief Warrant Officer (CWO). Due to the combined nature of the Canadian Forces, however, it is not impossible for an air force Chief Warrant Officer or a naval Chief Petty Officer 1st Class (CPO1) to rise to that post, especially in units with a high number of support trades personnel; examples might include a Logistics Branch CPO1 being appointed RSM of a service battalion, or an air force Communications and Electronics Branch CWO appointed to the position in a Communication Regiment of the Communication Reserve.

RSMs in the Canadian Forces are sometimes informally referred to in third person by their appointment, for example "RSM Bloggins". While the commanding officers of RSMs universally hold the privilege of addressing them as "RSM", the practice of doing so by subordinates may be governed by regimental tradition. In no case is an RSM ever addressed simply as "Sergeant Major". In military organizations, the commanding officer (CO) is the officer in command of a military unit. ...

The practice of subordinates addressing the RSM as "Sir" or "Ma'am" applies only to RSMs who are army or air force CWOs; naval CPO1s are universally addressed as "Chief", regardless of any appointments held.

The equivalent position in a higher formation, such as a brigade-group or Land Force Area, is sometimes termed "Regimental Sergeant Major" (for example, the Regimental Sergeant Major of 1 Canadian Mechanized Brigade Group[1]), but this practice is not universal (for example, the Brigade Sergeant Major of 2 Canadian Mechanized Brigade Group[2]). 1 CMBG Crest 1 Canadian Mechanized Brigade Group (1CMBG) is a Canadian Forces brigade group that is part of Land Forces Western Area of the Canadian Army. ... 2 Canadian Mechanized Brigade Group (2CMBG) is a Canadian Forces brigade group that is part of Land Forces Central Area of the Canadian army. ...

Singapore

Like most Commonwealth forces, the RSM in the Singapore Armed Forces is usually the senior warrant officer of the unit.

• in the presence of a comparatively senior warrant officer holding a commissioned officer's appointment (often in the field of logistics).
• in NS (reserve equivalent) battalions which often have NSmen sergeants fast-tracked for promotion holding the RSM appointment.

In Singapore, it is no disrespect for officers senior in rank to the RSM to address him as "RSM". As a warrant officer, he is addressed "Sir" by those junior in rank. As one of the older non-commissioned officers, he is often addressed "encik" (meaning "uncle") as well. National Service (NS) in Singapore is the name given to the compulsory conscription of all male Singapore citizens and second-generation permanent residents upon reaching the age of 18. ...
