Like all military organizations, the Republic Army and Navy rely on ranking hierarchies to maintain a clear chain of command. These ranks are listed below, from highest responsibility to lowest. Unless otherwise noted, ranks are used across service branches.
Supreme Commander General (Army), Admiral (Navy)
Colonel (Army), Commodore (Navy)
Major (Army), Group Captain (Navy)
Sergeant (Army), Petty Officer (Navy)
The term “commander” may be used to describe anyone in a position of command and is not reserved for a specific rank.
Due to the great diversity of service personnel present in the Republic military, regulations specify that the honorific “sir” should be used when addressing any personnel of higher rank than oneself, regardless of the species, gender or position of the addressee.
