Antigravity pack

The Antigravity Pack is used by Ranger Elites to maneuver in low-gravity or zero gravity situations. It provides extreme mobility, and in no way hinders their combat effectiveness. This pack allows Elites to easily dodge enemy fire and to get in close or retreat when needed. They most likely work similar to a Banshee's engines, encasing the user in an anti-gravity field that keeps them suspended in the air.

Trivia

 * They are used by Elite Rangers and also by the Heretic Leader Sesa 'Refumee.
 * The UNSC uses less refined and less effective T-PACKs for zero G movement.
 * In Halo 3, Brutes use a crude version of the Antigravity pack, the Jump Pack.
