If you have a college degree, a soldier can enter the Army with a E-4 ranking. The Army's enlisted ranks are broken down into The remaining soldier ranks are as listed: Private (E-2), Private First Class (E-3), Specialist (E-4), Corporal (E-4), Sergeant (E-5), Staff Sergeant (E-6), Sergeant First Class (E-7), Master Sergeant (E-8), and First Sergeant (E-8). Private First Class (E-3) are the basic workforce and strength of the Army. It's common for servicemembers to remain as a Non-Commissioned Officer (E-4 through E-6). However, to be promoted to E-4 through E-6 status, a soldier must perform certain tasks and have qualities that are transferred into a point system that is part of a nation-wide competition. Junior Enlisted Ranks (E-1 through E-4) are automatically promoted based on completing specific service periods.
