Acommand sergeant major (CSM) is anon-commissioned rank and position of office in theUnited States Army. The holder of this rank and position is the most senior enlisted member of acolor-bearing Army unit (battalion or higher). The CSM is appointed to serve as a spokesman to address the issues of all soldiers, from enlisted to officers, fromwarrant officers and lieutenants to the Army's highest positions. As such, they are the senior enlisted advisor to thecommander. The exact duties vary depending on the unit commander, including observing training and talking with soldiers and their families.

The command sergeant major, as the most senior sergeant of a color-bearing unit, began in July 1967, with a final definition of duties in December 1975. In contrast, the duties of asergeant major have been defined in the U.S. Army since the days ofvon Steuben (1779). The need for a senior enlisted advisor to a commander was recognized in theVietnam War era (December 1966).[1]
CSMs are selected for assignment only after training as top enlisted leaders.[1][2][3]
