The current chief master sergeant of the Space Force is Roger A. Towberman, who assumed the office on 3 April 2020.[2]
Responsibilities
The chief master sergeant of the Space Force serves as the senior enlisted advisor to both the chief of space operations and the secretary of the Air Force on all matters regarding the welfare, readiness, morale, proper utilization, and progress of Space Force enlisted members and their families.[2]
Insignia
The first rank insignia worn by the chief master sergeant of the Space Force, was based upon the rank insignia of the Air Force's chief master sergeant rank insignia, with other components, such as the two stars, designed to be consistent with the senior enlisted advisor rank of the other services. The delta, orbit, and globe elements at the center of the rank were taken from the seal of the United States Space Force. However, unlike the insignia of the Chief Master Sergeant of the Air Force which has a Laurel wreath around the central star within the rockers, the CMSSF insignia does not.[2] On 20 September 2021, new insignia for all enlisted in the Space Force was introduced, including the CMSSF.[3][4][5]
