Sergeant First Class - United States Army

United States Army

Sergeant First Class (SFC) is the seventh enlisted rank (E-7) in the U.S. Army, above Staff Sergeant and below Master Sergeant and First Sergeant, and is the first senior non-commissioned officer rank. A Sergeant First Class is typically assigned as a Platoon Sergeant at the company level or Battalion Operations Noncommissioned Officer in Charge at the battalion level, but may also hold other positions depending on the type of unit. In a combat arms role, Sergeant First Class is typically in charge of anywhere from 18 soldiers and 4 tanks in an armor platoon to 40 soldiers in a rifle platoon. A Sergeant First Class' primary responsibility is training and mentoring Lieutenants, tactical logistics, tactical casualty evacuations, and the senior tactical advisor to the platoon leader. With today's operations tempo, a Sergeant First Class may fill the role of platoon leader if no suitable officer is available. Sergeant First Class replaced the now defunct rank of Technical Sergeant in 1948.

A Sergeant First Class is addressed as "sergeant" except in certain situations; such as cannon artillery units, where a Sergeant First Class serving as Platoon Sergeant is commonly referred to as "Smoke." They may also be culturally referred to as "platoon daddy," though not directly or in a professional setting. If a Sergeant First Class is appointed to fill the role of First Sergeant, he or she is addressed as "First Sergeant." Typically a Sergeant First Class assigned on a manning document to fill a first sergeant role while being promotable to Master Sergeant can be frocked to First Sergeant rank and hold the insignia due its position.

Sergeant First Class is the first rank in the US Army to be selected by the centralized promotion system. As such it is considerably more difficult to achieve than the previous ranks. A Sergeant First Class is considered the first senior non-commissioned officer, and gains not only notice but several benefits due the position. For example, a Sergeant First Class cannot be demoted by standard non-judicial punishment.
