Company sergeant major

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. In combat, his prime responsibility is the supply of ammunition to the company. He also oversees the distribution of other supplies, such as water or food, although that responsibility is mainly that of the company quartermaster sergeant (CQMS), and evacuating the wounded and collecting prisoners of war.

For military units of the same level as a company, the equivalent may be squadron sergeant major (SSM) or battery sergeant major (BSM). In the Household Cavalry, squadron corporal major (SCM) is the equivalent. First sergeant and Kompaniefeldwebel (formerly Hauptfeldwebel in the Wehrmacht and Nationale Volksarmee) are the United States Army and German Heer equivalents respectively.

In the Canadian Forces, the CSM appointment is normally held by a master warrant officer. The appointment is sometimes held by a warrant officer, responsible for a smaller number of personnel.

In the Canadian Forces, the SSM/BSM/CSM is referred to as "Sir/Ma'am" by subordinates, or as "Sergeant Major". Superiors refer to him/her generally as "Sergeant Major" or "CSM". If the position is held by a warrant officer, subordinates address the CSM as "Warrant".

In the Singapore Armed Forces, the CSM appointment is usually held by a staff sergeant, master sergeant (the usual rank for a CSM of a non-HQ company) or second warrant officer (the usual rank for a CSM of a battalion HQ company). He may be addressed as "CSM" by superiors, and as "Sergeant Major" (for a staff sergeant or master sergeant) or "Sir" (for a second warrant officer) by subordinates. The CSM is often respectfully addressed by all as "Encik", Malay for "Mister", but the permission for junior enlisted men to do so should not be taken for granted.
