Whilst we find the path.”
The Honor Guard was a special unit within the Covenant tasked with providing security for the High Council. It mainly consisted of Sangheili until the Great Schism, when they were replaced by Jiralhanae. They are the most skilled of warriors and are hand-picked for the duty of protecting the High Prophets and members of the High Council from any danger. Wherever a High Prophet is located, Honor Guards are always by their side, perhaps up to as many as 300 Honor Guardsman for each Prophet.
Before the Great War
After the Sangheili-San'Shyuum war, the two sides formed the Covenant. The San'Shyuum were to be the governmental leaders and scientists, with the Sangheili as their protectors and main soldiers.
In 2531, the Honor Guard was present at the Battle of Shield 0459, where they defended the Prophet of Regret in his attempt to reactivate a fleet of Forerunner ships in spite of the interference from the crew of UNSC Spirit of Fire. In the battle, the Honor Guard, alongside the Arbiter, fought the humans as they prepared to destroy the Shield World. They were defeated by the Spartan-II supersoldiers of Red Team. The Honor Guards in this did not wear the traditional ceremonial armor.
Between 2542 and 2552, the Honor Guard were charged with defending a Lesser Prophet on a Covenant-controlled planet that served as a major logistics base. A team of ODSTs infiltrated the planet and sniped the Prophet from a distance of two miles before the Honor Guard could intervene.
On October 20, 2552, Covenant Ground and Naval forces invaded Earth. The High Prophet of Regret and his fleet came to Earth to find The Ark, a facility where they could fire all of the Halo Installations and complete The Great Journey. Being pursued by United Nations Space Command forces, Regret and his flagship went into slipspace in New Mombasa, Kenya.
And a few hours later, SPARTAN John-117 and a few Marines initiated an assault on the temple. The Sangheili Honor Guardsmen fought furiously to protect their Prophet from the SPARTAN, though they were overpowered. This allowed for the Human to kill the Prophet of Regret. However, it is revealed later that the High Prophet of Truth refused to send Regret reinforcements, thus letting John-117 kill the Covenant Hierarch, and discrediting the Sangheili at the same time. By doing this, Truth killed two birds with one stone, he eliminated any struggle for power that Regret may spark within the Covenant and discredited the Sangheili simultaneously.

Due to their mistakes in allowing the killing of a High Prophet, the High Prophets of Truth and Mercy ordered the Sangheili to step down as the protectors of the Prophets. The Jiralhanae filled in the void left by the disgraced Sangheili.

Death of Mercy and the Dreadnought
Later during the battle on High Charity, the Prophets of Truth and Mercy along with their personal Jiralhanae honor Guards fled towards a landing pad where they would leave on the Dreadnought in the middle of the city.
During this, the Flood, led by the Gravemind, began their invasion of High Charity. A lone Infection Form that slipped past the Jiralhanae, grasped onto Mercy's throat and began the process of turning him into a Proto-Gravemind. Truth, not wanting any potential threat to his ultimate supremacy, allowed the old Prophet to die.
