Special Operations Sangheili are extremely skilled fighters, sent in by the Covenant to accomplish the most dangerous and difficult of missions. They have superior accuracy, fire in longer bursts and have slightly stronger shielding than regular Sangheili. Most notably, SpecOps Sangheili operate in squads, are extremely skilled and are accurate grenade throwers. They are equipped with an Active Camouflage system, but rarely use it, except to get into position without being noticed though they have also been known to sometimes operate similarly to Stealth Sanghelli using camo during battle. They can be seen leading Special Operation Grunts into battle, but only in Halo 2. Identification: Purplish armor in Halo 3, Dark Red armor in Halo: Reach.
