Supreme Commander

The title Supreme Commander is used in the Covenant Navy. The title has only been known to be issued to Sangheili commanding large fleets and armadas. Despite the high status of the title's name, a Supreme Commander is likely lower in rank than Imperial Admiral, which appears to be the overall head of the navy..

For most of the Covenant's history, this rank was held by the Sangheili race until the Great Schism, when the Jiralhanae assumed most of the Covenant's higher ranks.

Description
Supreme Commanders command large Covenant fleets, such as the Fleet of Particular Justice, which was formerly led by Thel 'Vadamee before he was stripped of his rank due to his failure at Installation 04. Lesser fleets may be commanded by Fleet Masters, who are of a lower rank than the Supreme Commander.

During the Great Schism, it is possible that the Jiralhanae took these positions from the Sangheili, as the majority of the Sangheili's other posts were taken over. However, no Jiralhanae Supreme Commanders have been mentioned. Some Sangheili Supreme Commanders may have escaped to fight the Jiralhanae, although it is also possible that they were executed, similarly to the councilors.

In addition to commanding naval forces, Supreme Commanders apparently have some degree of authority over the ground troops attached to their fleet. For example, Supreme Commander Thel 'Vadamee ordered part of his fleet's special operations contingent to conduct a mission to the agricultural support ship Infinite Succor during the Battle of Installation 04.

Dress
When commanding a fleet, Supreme Commanders sometimes wear purple armor with a purple cloak that wraps around and over the shoulder pauldrons. The armor also features an ornate helmet. It is likely that this non-standard armor serves a ceremonial purpose. The Supreme Commander's unusual helmet looks somewhat similar to that of the Sangheili Combat Harness. However, when Thel 'Vadamee appeared before the Covenant High Council, he sported golden Zealot armor. This may signify that the cloak is only used when commanding fleets, or that he chose not to wear his cloak before the Council as a sign of modesty. While commanding the Third Fleet of Glorious Consequence, Supreme Commander Luro 'Taralumee wore armor that resembled that of most Sangheili Zealots, though it was more ornate, possessing prongs similar to those on 'Vadamee's helmet.
