Sangheili Honor Guardsman
- "The Sangheili honor guard was always vigilant and almost inert when at peace. One never had to worry about what a Sangheili might do any more than one worried if the stars would come out at night."
- —The Minister of Discovery remarking on the stoic nature of the honor guard.
Honor guardsmen were among the most skilled of all Sangheili warriors and were hand-picked for the duty of protecting the High Prophets and other high ranking officials in the Covenant High Council. The Lights of Sanghelios were a revered elite unit among the Sangheili honor guards.
Honor guardsmen in service to the Honor Guard of the Covenant wore highly ornate armor, colored in a combination of glowing red and orange. It featured jutting spikes and pauldrons, though they sometimes wore non-ceremonial armor for the sake of practicality. It is unknown how many Sangheili honor guardsmen were in service, though the Sanctum of the Hierarchs on High Charity could accommodate as many as three hundred.
Honor guardsmen were expected to immediately kill anyone who drew a weapon in the presence of a Hierarch, though they might stand down should an Arbiter do so. In addition, they kept order during important meetings within the High Council. Although the position was a great honor, it was seen by some Sangheili as a merely ceremonial duty and a way to silence those who were aware of the Hierarchs' duplicity.[verification needed]
The Sangheili honor guardsmen were likely instated soon after the signing of the Writ of Union, which led to the establishment of the Covenant. For thousands of years, the Sangheili protected the Hierarchs and the other Prophets according to the Writ's strictures. After the death of the Prophet of Regret during the Ninth Age of Reclamation in November 2552, the Prophets of Truth and Mercy replaced the Sangheili honor guards with the Jiralhanae. This "Changing of the Guard" was a major step in a carefully planned coup that soon devolved into the Great Schism. Some of the honor guardsmen killed themselves after learning of the Prophets' treachery. Others assisted Arbiter Thel 'Vadamee in stopping Tartarus, the Chieftain of the Jiralhanae, from activating Halo Installation 05 and therefore killing all sentient life in the galaxy.
 Halo Wars gameplay
In Halo Wars, Sangheili honor guardsmen are the leader-specific unit of the Prophet of Regret. They wield energy swords and deal tremendous damage to infantry. They are trained directly from the Citadel. They initially lack energy shields, though they can be upgraded with them. They can also be outfitted with active camouflage.
