A flag officer signified a rank within a faction's naval forces. Within the structure of the Chiss Ascendancy, a flag officer denoted a ranking officer equal to or higher than that of a Commodore. When a Chiss officer attained flag rank, they underwent a ceremony severing their connections to their Chiss family; during this event, the Supreme Admiral proclaimed "the Ascendancy is now your family." This measure was implemented to prevent familial politics from influencing the judgements of the military.
Within the starfleet of the Galactic Empire, flag officer ranks included (in descending order): Admiral of the Fleet, Grand Admiral, Fleet Admiral, Admiral, Vice Admiral, Rear Admiral, and Commodore. Admiral Kassius Konstantine was presented as an ideal example of a flag officer in the Imperial Navy.
