Title: Sergeant major
Content:  A sergeant major is an appointment, not a rank. It is normally held by the senior warrant officer of an army or marine unit. These appointments are made at several levels, for example: the senior warrant officer of a company, battery or squadron; or the senior warrant officer of a battalion or regiment. The title normally consists of the unit title (e.g. 'company') followed by 'sergeant major', and abbreviated by the initials (e.g. CSM). A sergeant major of a regiment or battalion is known as a regimental sergeant major, rather than a "regiment sergeant major" or "battalion sergeant major". The sergeant-major of a unit is responsible to the commanding officer for advising them on matters relating to non-commissioned members (NCMs) of that unit. Sergeant majors are normally addressed as "sir" or "ma'am" by subordinates, and as "sergeant major", by their full title (or its abbreviation), or as "Mr" or "Ms" by superiors. In the British Armed Forces, the plural is sergeant majors and not sergeants major as it is in the United States.

The Chief of Staff of the Army created the position in 1966 after asking leaders of the major commands for a personal recommendation. He asked that it not be considered a near-retirement type assignment. He listed seven duties and functions he expected the Sergeant Major to perform, including service as a personal adviser and assistant on matters pertaining to enlisted soldiers. From 4,700 proposed candidates, 21 nominees were selected. Finally chosen was the only one then serving in Vietnam, Sergeant Major William O. Wooldridge of the 1st Infantry Division. The other services later followed, creating the positions of Master Chief Petty Officer of the Navy and Chief Master Sergeant of the Air Force in 1967, Master Chief Petty Officer of the Coast Guard in 1969, Senior Enlisted Advisor to the Chairman in 2005, and Chief Master Sergeant of the Space Force in 2020.
