Supreme Commander

Supreme Commander is one of the highest Covenant Sangheili ranks.

Summary
For most of the Covenant's history, this rank was held by the Elite race, but may have been replaced by Brutes after the Great Schism. Supreme Commanders command Fleets and Armadas.

Description
Supreme Commander is the rank which commands large Covenant Fleets, such as the Fleet of Particular Justice formerly led by Thel 'Vadam before his failure change of rank to Arbiter. Lesser fleets may be commanded by Fleet Masters, a lower rank than the Supreme Commander.

The particular Supreme Commander in the aforementioned text was a friend of, and yet superior to, Special Operations Commander Rtas 'Vadumee and would later become the Arbiter.

During the Civil War of the Covenant, it is possible that Brutes took these positions from the Elites, but none has ever been seen. But even so, some Elite Supreme Commanders may have escaped to fight the Brutes.

Appearance
When commanding a Fleet, Supreme Commanders wore purple armour with a cloak that wraps around and over the armor piece of their shoulders, and a showy helmet, probably with ceremonial purpose. The Supreme Commander's unusual helmet looks somewhat similar to the Halo 3 Elite Combat Helmet when compared closely. However, when Thel 'Vadamee appears before the Covenant High Council, he sports golden Zealot armor.

Trivia

 * Thel 'Vadamee was the only known Supreme Commander.
 * Supreme Commander may be a type of Zealot.
