Jump pack
From Halopedia, the Halo wiki
The Jump Pack is a piece of equipment used by the Jump Pack Brute. It allows for accurate and precise jumps from location to location, giving the Brutes the mobility and tactical flexiblity that they often lack. Unlike the Antigravity Packs used by Ranger Elites these do not provide them with a permenant airborne prescence or the ability to accuratly fight and hover. It is deisgned for use on terrestial enviroment where after the inital jump they can rely on gravity to bring them back to ground, whereas in zero gee enviroments they would simpy be blown out into space .
