The military rank of Fleet Admiral was used by the navies of the New Republic, the Galactic Republic (Lok), the Galactic Empire (Mar) and the Galactic Alliance (Eylon). The rank was often used to denote a commissioned officer who was superior to an Admiral. The Republican governments used the title to denote the leader of individual fleets while the Alliance governments used the title to denote the administrative military leadership of regions of space. The Imperial rank of Fleet Admiral was used as a staff rank rather than a field rank. The title of Fleet Admiral was the Naval equivalent to Field Marshal/Surface Marshal.
