A Command Sergeant Major (CSM) is a non-commissioned rank and position of office in the United States Army. The holder of this rank and position is the most senior enlisted member of a color-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, from warrant officers and lieutenants to the Army's highest positions. As such, they are the senior enlisted advisor to the commander. The exact duties vary depending on the unit commander, including observing training and talking with soldiers and their families.
