Forerunner Fleet Command[1] was a Forerunner military organization in command of the Forerunner Navy and possibly the entire Forerunner military, including the Suppression Fleet, Security Fleet, and Emergency Circumstance Fleet. During the final stages of the Forerunner-Flood war, Fleet Command ordered that all personnel register their equipment keycodes with them. It is likely that the Iso-Didact was head of this organization, as he seemed to be the overall Forerunner military commander.
