Senior Master Sergeant (SMSgt) is the eighth enlisted rank (pay grade E-8) in the U.S. Air Force, just above Master Sergeant and below Chief Master Sergeant and is a senior non-commissioned officer (SNCO).
Promotion to Senior Master Sergeant is the most difficult enlisted promotion to attain in the Air Force. Senior Master Sergeants typically assume superintendent duties, overseeing enlisted members' efforts to accomplish a major segment of a unit's mission, in preparation for promotion to the rank of Chief Master Sergeant. They are expected to serve as mentors for non commissioned and junior commissioned officers. Senior Master Sergeants are sometimes referred to by the nickname of "Senior". This usage is an informal one, however, and would not be used in an official or formal setting. The official term of address is Senior Master Sergeant or Sergeant.
