Master Sergeant

United States

A Master Sergeant is:

• the seventh enlisted rank in the United States Air Force, just above Technical Sergeant and below Senior Master Sergeant. It is abbreviated as "MSgt." Advancement to Master Sergeant is one the most significant promotions within the enlisted Air Force. At the rank of Master Sergeant, the airman enters the senior noncommissioned tier and his or her duties begin to focus on leadership and management rather than technical performance. Per Air Force Instruction 36–2118, MSgts typically serve as flight chiefs (analogous to platoon sergeants in the US Army) and section chiefs (leaders of duty sections within a squadron).
• the eighth enlisted rank in the United States Army, just above Sergeant First Class and below Sergeant Major. It is abbreviated as "MSG."
• the eighth enlisted rank in the United States Marine Corps, just above Gunnery Sergeant, below Master Gunnery Sergeant, and equal in grade to First Sergeant. It is abbreviated as "MSgt." Master Sergeants in the U.S. Marine Corps provide technical leadership as occupational specialists at the E-8 level. General command leadership at this paygrade is provided by the separate rank of First Sergeant.

All Master Sergeants are non-commissioned officers.

Republic of Singapore

Master Sergeant (MSG) is the highest non-commissioned officer (known as Specialist in Singapore) rank in the Singapore Armed Forces (SAF), ranking just above Staff Sergeant (SSG). The MSG rank insignia is 3 up pointing chevrons, 3 down pointing chevrons, and a Singapore coat of arms in the middle.

MSGs, being the most senior Specialists in the SAF, play an important role in guiding young soldiers along. They usually hold senior Specialist positions. MSGs are also not usually addressed as "Sergeant", which would be reducing their rank, but as "Encik" (Malay term of respect).
