The term 'Army Noncom' refers to two different ranks in the United States Army: Sergeant (SGT) and Sergeant First Class (SARGE). Sergeants are the most junior of the non-commissioned officers, and are responsible for leading small groups of soldiers. Sergeant First Class is the next rank up from Sergeant, and they are responsible for leading larger groups of soldiers. Both ranks are important in the Army, as they provide leadership and guidance to the enlisted personnel.
