Phoenix Logs/Banished Units/Honor Guard
From Halopedia, the Halo wiki
Personal guard of Shipmaster Let 'Volir.
These mercenaries are the infantry bodyguard of Let 'Volir, armed with energy swords and equipped with active camouflage. The Honor Guard can cloak for a limited time, allowing them to close to melee range and engage with their swords.
Borrowing the ceremonial gear and matching the martial prowess of the old Covenant Honor Guard, these mercenary sword masters evoke the traditions and accomplishments of their forebears in the service of their Shipmaster and his unconventional arrangement with Atriox and the Banished. Though the Honor Guards' motives are not as pure as they once were, only a fool would dare risk their wrath by challenging their presumed honor and skill.
