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. These Elites, though never seen in actual battle, are believed to have the same sheilds as an Ultra Elite, with maybe slightly stronger sheilding than an Ultra Elite.

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.

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" (see below).

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.

It is theorised that Honor Guard Ultras are more likely to withstand the Brute onslaught than regular Honor Guards, due to their superior shielding and combat experience.

As recently found out the "Honor Guard Councillor" glitch, found at the end of the level Gravemind (Level),can sometimes have the body of the Ultra and the ornate armor pieces of an Honor Guard, including the helmet. This fortunately creates the perfect in-game image of the Honor Guard Ultra. However, it is not truly representative of an Honor Guard Ultra, given that it is actually a Zealot in terms of statistics.
