Sangheili Ranger Commander
From Halopedia, the Halo wiki
Sangheili Ranger Commanders appear in Halo: Reach as the BOB Easter egg.
Halo 5: Guardians
Ranger Commanders appear in Warzone on the map Escape from ARC. Two spawn as the second boss on the level, one in each tunnel of the East and West Armories. Each is accompanied by two Sangheili Rangers. They are armed with storm rifles and throw plasma grenades. Killing one will award the team 25 VP, and earn the player a Boss Takedown medal. As most simulated Sangheili bosses in Warzone, they do not wear their correct harness, in their case the Ranger variant, instead sporting the Warrior-class harness if Legendary or the Commander-class harness if Mythic.
