War Chieftain is the second highest Jiralhanae rank. The rank is featured in Halo 3, with War Chieftains playing a significant role in the Covenant's occupation of Earth and defense on the Ark. It is observed that most War Chieftains carry powerful ranged weapons, rather than gravity hammers. In Halo 3: ODST, however, War Chieftains sometimes wield gravity hammers, making them some of the most powerful enemies in the game, as they have stronger shielding and are higher ranked than regular Jiralhanae Chieftains.
