Jiralhanae Bodyguard

The Brute Bodyguard is a Brute (Jiralhanae) specialty rank. They are responsible for the protection of their packs Chieftain. They are also responsible for the enforcement of tribal law. Whenever there is a Chieftain nearby, you will encounter Brute Bodyguards which look very similar to Captains. Bodyguard Brutes are also seen to be protecting Truth on the level The Covenant. They are likely the replacement for the Honor Guard being that Tartarus also had Honor Guard protection. Brute bodyguards seem to favor Covenant weapons such as the Plasma Rifle and Carbine rather than their own native tech. They come in two variants: A more common, silvery-blue (with red under-armor) variant, and a less common, silver armored (with red under-armor) variant. Whether these variants signify differences in behavior or strength is unknown as of yet. They are first seen in Sierra 117.

Differences with the Brute Captain
The Brute Captain Ultras and the typical Brute Bodyguard, look almost exactly the same (especially in dim lighting), but there are in fact slight differences in their Power Armor color and power. The Brute Captain Regulars have a violet tinge to the armor, but the Bodyguards have a more indigo color and their under-armor and garments are light crimson; however, in the heat of combat it 's extremely difficult to differentiate between the two ranks. They supplant the Brute Honor Guards, from Halo 2.
