Imperial Admiral is the highest non-political rank a Sangheili could obtain. It is much higher than a Zealot, as Xytan 'Jar Wattinree promoted Voro Nar 'Mantakree to the position of Fleet Master. It is the highest Covenant Navy rank. Imperial Admirals control large Fleets of warships and operate on a very high-ranking Covenant Flagship in the Covenant Navy such as an CAS-class Assault Carriers, CSO-class supercarriers, or other very powerful capital warships within the Covenant Navy.
