CMSgt stands for Chief Master Sergeant, a US Air Force and Space Force rank abbreviation.

Highest regular Air Force and Space Force enlisted rank, pay grade E-9, insignia five chevrons below the star and three above. Chiefs lead squadrons' and wings' enlisted forces as senior advisers and career-field managers.

Example: CMSgt Lawson told the first-term airmen that the chief's group would mentor every new arrival.

Usage notes

By law no more than 1 percent of a service's enlisted force can hold pay grade E-9. Chiefs are addressed as "Chief" and are selected by a central board. Senior chiefs at wing level and above serve as command chief master sergeants, whose insignia adds a wreath around the star.
