Enlisted - CSM - Retired - Command Sergeant Major T-Shirt

In the U.S. Army, sergeant major (SGM) refers to both a military rank and a personnel slot[disambiguation needed], or position title. It is the highest enlisted rank, just above first sergeant and master sergeant, with a pay grade of E–9, NATO rank OR–9. The leadership variation—command sergeant major (CSM)—is the senior enlisted advisor to the commanding officer. The leadership position carries with it certain ceremonial functions such as caring for the unit's colors (flag). Additionally, CSMs serve as monitors of, and advocates for, the enlisted soldiers in the command. This position mostly exists in units of battalion size and larger.
