Main Tag:
Description: In the United States Army, the rank of first sergeant (abbreviated 1SG) is an E-8 paygrade rank above the rank of sergeant first class (SFC), and below the rank of sergeant major (SGM) or command sergeant major (CSM). It is equal in grade to master sergeant (MSG), although the two ranks have different responsibilities. Both ranks are identical with three chevrons up (standard sergeant insignia) and three curved stripes underneath "down" known as "three up and three down", though the first sergeant has the lozenge "diamond" in the middle.
