Sangheili

The Sangheili, better known as Elites, lead the Covenant's military forces.

After the Writ of Union, the Elites helped the Prophets in reaching godhood.

As they traveled across the stars, they would come across countless Forerunner artifacts as well as several other species that would join the Covenant.

The Halo Combat Evolved Elite classes were: 1) Minor, 2) Ultra, 3) Major, 4) Stealth, 5) Zealot.

The Halo 2 Elite classes were: 1) Minor, 2) Ultra, 3) Major, 4) Ranger 5) Stealth, 6) Special Operations, 7) Honor Guard, 8) Honor Guard Ultra, 9) Zealot, 10) Councillor, 11) Arbiter.

The Halo 3 Elite classes were: 1) Combat, 2) Assault, 3) Flight, 4) Ascetic, 5) Commando, 6) Shipmaster, 7) Arbiter.

The Elites, sadly enough, were not seen alive in Halo 3 ODST.

The Halo Reach Elite classes were: 1) Minor, 2) Major, 3) Ranger, 4) Spec Ops, 5) Ultra, 6) Field Master, 7) Zealot, 8) Shipmaster.

Some of the famous Elites were: Rtas 'Vadumee (Half Jaw) was the Shipmaster of the 'Shadow of Intent', Ripa 'Moremee was the 17th Arbiter, & Thel 'Vadumee, was the 18th Arbiter.

Rtas was in the Battle of Installation 05, the Flood Battle of high Charity (this is when he lost his right jaw), the Flood Battle of Earth, & the Battle of Installation 00. Ripa was in the Battle of Harvest, the Battle of Arcadia, & died at the battle of a Shield World to SGT John Forge. Thel was in the same battles as Rtas, but also was in the final battle against the Flood.

They remained loyal to the Covenant alliance, until the Battle of Installation 05 in which the High Prophet of Truth would betray them by replacing them with the Brutes. During the Covenant Civil War, The 18th Arbiter (Thel 'Vadumee) assisted SGTMAJ Avery Johnson, CMDR Miranda Keyes, & 343 Guilty Spark stop Brute Chieftain Tartarus from lighting Installation 05 and eradicating all Recorded Sentient life in the galaxy.

During the second Battle of Earth, Thel 'Vadumee assists John-117 in fighting not only the Covenant, but also the Flood. As the Flood spreads across Voi and surrounding areas, The Shadow of Intent, an Elite Assault Carrier, and the Elite fleet arrive to help in killing the Flood & the Battle of Installation 00.

In the end, Thel 'Vadumee killed Truth with an Energy Sword through the back, ending the Human-Covenant War, as well as the Covenant Civil War. Later Thel would help John, Avery, & Cortana in ending the second Flood War.
