Sangheili Ultra

Were you looking for the Honor Guard Ultra, also known as the Light of Sanghelios?

"On the blood of our fathers. On the blood of our sons."

- Sangheili Ultra's mantra.

Ultra is the highest regular rank among the Covenant's Sangheili warriors and later those of the Covenant Separatists.

Description
Sangheili Ultras command specific operations, serving as field officers. They are directly subordinate to Zealots, who command fleets and armies. They are sometimes deployed on high-priority missions, often alone. For example, Ultras are known to command Scarab assault platforms. However, they often engage in open battle.

Ultras wear pearlescent armor with higher-than-average shield strength. Ultras wear white armor with red markings and a crested helmet similar to the of the councilors. In combat, Sangheili Ultras typically wield plasma rifles, though they also commonly use plasma repeaters and concussion rifles. Ultras are sometimes seen with energy swords in close combat.

Trivia

 * In Halo 2 and Halo Reach, all Sangheili encountered will become Ultras with the Thunderstorm skull activated.
 * In Halo: Reach multiplayer, the Ultra Combat Harness is made available after the player reaches the rank of Warrant Officer.
 * In the level Floodgate in Halo 3, the corpses of the Ultras in the crashed cruiser can be infected by the Flood. They will sometimes pick up dropped energy swords lying on the ground. This may seem alarming, but the Flood apparently either do not have animations for the energy sword or are simply not programmed to use it, because they will simply follow the player without attacking. They retain the white-colored armor of the corpses, making them look very distinct from other Flood forms.
