Whenever a small fleet is needed for any mission away from the entirety of the Covenant Navy, a Fleet master will be assigned and given command of several warships for the mission. In this regard, they could be considered the Covenant equivalent to a UNSC Rear Admiral. Since Fleet masters are of such a high rank, it is assumed that they may also command the entire fleet should their Supreme Commander or Imperial Admiral be incapacitated during space combat.
They normally operate from a large warship, such as a Reverence-class cruiser, as when Fleet master Voro Nar 'Mantakree operated from the Reverence-class cruiser Incorruptible during the Battle of Onyx.
Fleetmasters have been seen wearing the same yellow-gold armor as other zealot-level Sangheili.
