Line 7:
Sergeant First Class (SFC) is the seventh [[enlisted rank]] (E-7) in the [[United States Army|U.S. Army]], ranking above [[staff sergeant]] (E-6) and below [[master sergeant]] and [[first sergeant]] (E-8), and is the first [[non-commissioned officer]] rank designated as a senior non-commissioned officer (SNCO).
 
A sergeant first class is typically assigned as a [[platoon sergeant]] at the company level or ''battalion operations non-commissioned officer in charge'' at the battalion level, but may also hold other positions depending on the type of unit. In a combat arms role, a sergeant first class is typically in charge of from 18 soldiers and four tanks in an armor platoon to 40 soldiers in a rifle platoon. A sergeant first class' primary responsibilities are tactical logistics, tactical casualty evacuations, and serving as the senior tactical adviser to the platoon leader. Sergeant first class replaced the rank of [[technical sergeant]] in 1948. (However, the U.S. Air Force, which separated from the Army in 1947, retained the rank of technical sergeant and the U.S. Marine Corps had the rank of technical sergeant until 1959).
 
A sergeant first class is addressed as "sergeant" except in certain situations, such as field artillery units, in which a sergeant first class serving as platoon sergeant is commonly referred to as "Smoke". 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 [[frocking|frocked]] to first sergeant rank and hold the insignia due its position.{{Citation needed|date=October 2010}}
