Rtas 'Vadum

"Though you leave this world, you will come on the Great Journey when the time comes. Die with honor."

- Rtas 'Vadumee

Special Operations Commander Rtas 'Vadumee, or "Half-Jaw", as he is known unofficially, for his name is not mentioned in Halo 2 at all, is a Sangheili with white or "Ultra" armor, as Cortana calls those of his rank. He is a Commander of Covenant Special Operations forces. He is mostly recognizible because he is missing his left mandibles, hence the fan-name, "Half-Jaw".

Contact with the Flood
When the agriculture ship Infinite Succor was boarded by an unknown threat, Rtas 'Vadumee lead a team there to investigate, along with securing a Legate known as the Minister of Etiology. They encountered the Flood for the first time there. In an attempt to kill the Flood, 'Vadumee used the Engineering station to set a Slipspace course to the sun. During that time, it was revealed that the Legate had become infected, and Rtas had to battle an infected Kusovai. It was there that an Energy sword cut off his left mandibles. He managed to escape two minutes before the Slipspace Jump occured. He is believed to be the only survivor of the Infinite Succor mission.

Pillar of Autumn
'Vadumee was present when the Pillar of Autumn crashed on Halo, leading the Covenant Special Ops struggle against the Demon and the Flood. He managed to escape before the ring was destroyed.

The Heretics
'Vadumee was assigned to hunt down the Heretic leader, Sesa 'Refumee, on a gas mining platform over Threshold. Joining him was the Arbiter, recently sentenced to this position by the High Council. Aboard a Phantom, he provided valuable reinforcements to the Arbiter as he progressed through the facility. Eventually finding 'Refumee, they chased him into another part of the platform. 'Vadumee joined the Arbiter in his search on foot.

He was reminded of his past with the Flood by a familiar "stench", moments before running into a battle between the Heretics and the Flood. After clearing out the area of "parasites", he split up with the Arbiter to gain reinforcements. A short time later they further pursued 'Refumee until he locked himself behind an unbreakable energy barrier. Giving up, 'Vadumee was about to turn away when the Arbiter volunteered to cut the cables holding up the mine, possibly drawing out the fugitive. The Commander agreed, giving his partner his prized Energy Sword. Leaving the Arbiter to his work, 'Vadumee and his remaining forces left in a Phantom, and returned to High Charity.

Changing of the Guard
Back in High Charity, the Jiralhanae were taking over the position of Honor Guard to the High Prophets. Expressing his disdain to the Prophets of Truth and Mercy, 'Vadumee was disgusted by this radical switch in tradition and customs. However, Truth refused to hear any more complaints, and the Elite was sent away, swearing to relay the Prophets' decision to the council. As he left, Truth muttered to himself "Politics, how tiresome."

The Search for the Sacred Icon
Soon afterward, 'Vadumee was involved in the Covenant operations against the Flood and the UNSC Marines inside the Quarantine Zone.

Deactivating Halo
Word got out that the Prophet of Truth had his hands on the Sacred Icon and the Oracle and was going to begin the Great Journey. Commandeering a Wraith, 'Vadumee spotted a Scarab walker parked outside a Jiralhanae encampment. Making his way along the coast, a surprised 'Vadumee met up with the Arbiter, this time on a quest to find the Icon before Installation 05 could be activated. From the Arbiter, he was informed of the murder of the Council and the treachery of the Brutes. The Elites were interrupted by the arrival of Tartarus's Phantom and its escorts as they entered the Control Room. Wishing to avenge their fallen brothers, 'Vadumee and the Arbiter attacked the surprised Jiralhanae and met up with a squad of Hunters and other Elites. There, 'Vadumee split up with the Arbiter again, and was not present when he escorted Johnson to the Control Room. It is unknown what happened to him, though it is assumed he attempted to take back a Covenant CCS-class Battlecruiser that was hovering a distance from the battle area, as the last line said by 'Vadumee was that he was "going to take the cruiser back."

Trivia

 * 'Vadumee seems to express great care for those under his command, even Grunts. The latter is particularly unusual for an Elite. During the events of Succor, he is shown telling the Grunts to get behind the Elites. Most Elite commanders would've sent the grunts on ahead as cannon fodder. In his first shown conversation with the Arbiter, he tells him "These are my Elites. Their lives matter to me."
 * 'Vadumee is the only Elite NPC shown carrying his weapon in his left hand, at least once. This occurs during the level Quarantine Zone, in which he leaves the Arbiter to do battle with the Flood, saying "On your way Arbiter. I'll deal with these beasts."
 * 'Vadumee is the only Ultra featured that does not have black/steel as his secondary armor color. This may hint that secondary colors play an important role in an Elite's armor, much like modern day function badges play on military uniforms. Black may hint at infantry or ground combat positions while olive, as in 'Vadumee's case, may hint at Spec Ops. Or, it may simply imply that 'Vadumee is a slightly higher/lower rank or position than a normal Ultra.
 * 'Vadumee is the only Covenant NPC that is immune from all harm in game, much like his human counter parts, Sergeant Avery Johnson and Miranda Keyes.
 * Despite being an Ultra, 'Vadumee is seen answering directly to the high prophets, not a Zealot. It may be that his position of Spec Ops Commander may be a special rank, somewhere between Ultra and Zealot (Like a Colonel General).
 * 'Vadumee is the only Elite to feature the "Eye Glitch", when he uses Active Camo, his green eyes are still visible even though his body is not. It is only seen on the Arbiter level titled, The Oracle.
 * It is actually possible to fight and kill 'Vadumee. At the end of the level Gravemind, there is an elite which is spawned with random armor. A.K.A the Honor Guard Councilor. Sometimes, although rare, this elite will spawn with Half-jaws' face and armor.

Joyride Studios had originally planned to produce Rtas 'Vadumee Action Figures in the eighth series of the Halo 2 8-inch figures, but the production was cancelled because they felt it was pointless to release another Elite figure with a different paint job. Also, in light of the Halo 3 announcement, Joyride is hard at work producing figures for Halo 3. They did not feel that a Rtas 'Vadumee figure was worth producing.
