A Sergeant is an enlisted and non-commissioned officer army rank that is senior to a Corporal and junior to a Staff Sergeant. It is the equivalent of a navy Flight Sergeant. In the Imperial Army, Sergeants typically serve as Brigade Commanding Officers and have somewhat of a leadership authority to junior members. It is also common to address those with the rank: Staff Sergeant, Sergeant First Class, and Master Sergeant as simply "Sergeants" however, higher NCO ranks such as Sergeant Major and Command Sergeant typically demand for the full address of their respected rank. Army members tend to dub the sergeant that is in their command as "Sarge". Sergeants are commonly abbreviated as "Sgt" or "SGT".
