The seventh enlisted rank in the U.S. Air Force, just above technical sergeant and below senior master sergeant. It is abbreviated as "MSgt." Advancement to master sergeant is one of the most significant promotions within the enlisted Air Force. At the rank of master sergeant, the Airman enters the senior non-commissioned tier and his or her duties begin to focus on leadership and management rather than technical performance.
MSgts typically serve as flight chiefs (analogous to platoon sergeants in the U.S. Army) and section chiefs (leaders of duty sections within a squadron). It is also the lowest rank in the Air Force that one can hold in order to attain the special duty position of first sergeant. These Air Force first sergeants occupy the grades of E-7 through E-9 and are referred to officially as "first sergeant" regardless of their pay grade, and unofficially as "first shirt" or simply "the shirt." In 1991 the Air Force changed its NCO insignia so that a maximum of five stripes, or rockers, were placed on the bottom of the chevrons. The master sergeant rank insignia was changed by removing the bottom (6th) rocker, and relocating it above as a single chevron, on top of the five lower stripes.
