They may not be Guardians of the Galaxy, but Space Force has chosen “Guardians” for the name of its personnel.

Space Force is the sixth branch of the US military, sharing the same relationship with the Air Force as the Marines do with the Navy. The new military branch was formed as more countries and corporations are turning their attention to the final frontier. Space Force’s goal is to protect US interest as space becomes both commercialized and militarized.

Space Force made the announcement via its Twitter feed:

Guardians. #SemperSupra!
