Jiralhanae Power Armor
From Halopedia, the Halo wiki
Power Armor [1] (can be heard being reffered to by a marine in the first Brute encounter in Halo 3), is the newly acquired armor for Brutes during the events of the Covenant Civil War (adopted sometime after the battle at High Charity).
It features weak energy shielding, which does not recharge after a full shielding failure (infact it falls off). The armor itself augments the already incredibly resistant Brutes to be able to withstand projectile weaponry quite well, but it is not as durable as the underlying armor of Elites and Spartans.
Some models feature built in Cloaking Devices, such as that worn by Brute Stalkers. Others may be stronger and impervious to sticky grenades, such as the Power Armor worn by Brute Chieftains.
