Imperial Admiral

Imperial Admiral is a Covenant Sangheili (Elite) rank.

Rank
An Imperial Admiral operates on a high ranking Covenant Flagship such as an Assault Carrier, Supercarrier or other very powerful capital ships within the Covenant armada. They are of higher rank than a Zealot, as Xytan 'Jar Wattinree promoted Voro Nar 'Mantakree to the position of Fleet Master. It is revealed in Halo: Ghosts of Onyx that the Imperial Admiral controls the entire fleet of the Covenant. Little else is known about the rank other than that, but it seems likely that they are second only in rank to the Councilors, just above the rank of Supreme Commander.

Appearance
Their armor is silver, similar to that of an Ultra Elite, and covered with the gold Forerunner glyphs of 'sacred mystery', much like the Arbiter's. Such silver-and-gold Elite armor has been mentioned in Ghosts of Onyx and is superior in quality to the gold armor of a Zealot. When Xytan 'Jar Wattinree spoke to his Ship Masters, he did so by way of a massive holographic representation of himself, over 30 feet tall. It is not clear if this was a choice peculiar to Xytan or if all Imperial Admirals have similar holograms.
