Lights of Sanghelios

Honor Guard Ultra is a Covenant Sangheili (Elite) rank. This rank commands the lower Honor Guard Elites of the High Prophets. It is equal to the rank of Honor Guard Captain of the Brute Honor Guard, and to the Zealot in the standard Elite military.

They are likely more skilled than their subordinates, with years of experience in the Covenant Honor Guard, which is particularly impressive considering the prodigious combat abilities of any in the Honor Guard.

Appearance
These Honor Guard Elites sport the same ornamented armor as the rest of the Honor Guard, with the exception that the under armour they wear is white instead of crimson. This color is consistent with the Ultra Elites of the regular Covenant army, hence their title. There is a Glitch at the end of the level where the Master Chief finishes fighting in the Mausoleum of the Arbiters, an Honor Guard Elite with a Councilor Helmet sometimes appears.

Combat
Honor Guard Ultras have never been directly seen in combat. Many players believe that one appears at the end of the level Gravemind but this Elite is actually the glitch known as the "Honor Guard Councillor".

Two Honor Guard Ultras are seen in the cinematic of Sacred Icon (Level) when they, along with regular Honor Guard Elites, are stripped of their position, giving it up for the new Honor Guard Brutes and their Honor Guard Captains.

In addition, three Honor Guard Ultras are seen killed fighting the Brutes around the middle of the level Gravemind (Level). They wear Honor Guard armor but without helmets, as they no longer held that position when they were killed.
