The Rangers are a voluntary group of Sangheili that work in the least forgiving environment of all: vacuum. Their helmets completely encase their heads, protecting them from the vacuum of space. They wear a variant of Sangheili armor optimized for zero-gravity, non-atmosphere combat, similar in appearance to Halo 3's Flight armor permutation. Their armor is cobalt in color, brighter than that of the Sangheili Minor. They can pose a substantial threat, due to their unique movement options. There are also variants that use their equipment to give them a tactical advantage planet side, flying above and shooting from the air, confusing and demoralizing the enemy, similar to a Drone, but with more power and fewer numbers. They are often the security of a carrier in space. Identification: Cyan armor in Halo 2, White armor in Halo: Reach, Jet Pack.
