Description Sergeants major is a senior non-commissioned rank or appointment in many militaries around the world. In Commonwealth countries, Sergeants Major are usually appointments held by senior non-commissioned officers or warrant officers. In the United States, there are various degrees of sergeant major (Command Sergeant Major (CSM), Sergeant Major of the Army (SMA)), but they are all of the same pay grade.
In most Commonwealth forces, Sergeant Major is not a rank, but rather an appointment held by a warrant officer. A Sergeant Major will normally be the senior non-commissioned member of an Army or Marine unit. There are normally two grades of Sergeant Major, with the first grade being the senior soldier of a company, battery or squadron and the second, higher grade being the senior soldier of a batallion 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 is known as a Regimental Sergeant Major, rather than a Regiment Sergeant Major.
The sergeant-major of a unit is normally directly responsible to the Commanding Officer (CO) for all matters pertaining to dress, deportment, discipline, conduct, performance, standards and morale of the non-commissioned members (NCMs) of that unit. Sergeants Major are normally addressed as sir or ma'am by subordinates, and by Mr or Ms (surname) by superiors, with the term 'RSM'/'CSM'/etc reserved for the Sergeant Major's Commanding Officer.
