How to read it
DA Pamphlet 670-1 describes the command sergeant major insignia as three chevrons above three arcs with a five-pointed star within a wreath between the chevrons and arcs. The Army’s ranks page calls the command sergeant major the senior NCO of the command at battalion level or higher, who makes recommendations to the commander and staff and carries out policies and standards on the performance, training, appearance and conduct of enlisted soldiers. A battalion is commanded by a lieutenant colonel with a command sergeant major as the principal NCO assistant. Army Regulation 600-20 ranks the command sergeant major above the Sergeant major (E-9) and below the Sergeant major of the Army (E-9); all three are E-9 and are addressed as “Sergeant Major”.

The wreath
A Sergeant major (E-9) wears the same insignia without the wreath. Army Regulation 600-20 says command sergeants major are the E-9s formally selected by the Department of the Army for the Command Sergeants Major Program.
Outside the chain of command
The Army’s Soldier’s Guide (TC 7-21.13) says the NCO support channel at battalion level and higher begins with the command sergeants major, and that the first sergeant and command sergeant major are not part of the formal chain of command.
