A Command Sergeant is an enlisted and non-commissioned officer army rank that is senior to a Sergeant Major and junior to a Second Lieutenant. It is the equivalent to a navy Command Flight Officer. In the Imperial Army, the Command Sergeant is the highest enlisted rank and in some respects, has the authority similar to that of an officer. They may serve as army Legion Executive Officers or any similar high authority position. Command Sergeants are commonly abbreviated as "Csg", "Csgt", "CSG" and "CSGT".
