The Jumpack is a variant of the Jetpack but instead of giving a long controllable flight, the jumpack gives a rapid burst that last for three seconds rocketing the user into the air before slowing down and landing softly back down. With some practice the jumpack can be used effectively. The jumpack uses fuel which recharges when not in use. Only the Dark Trooper uses the Jumpack, however, in Star Wars: Battlefront: Renegade Squadron and Elite Squadron, it appears as an unlockable ability that can be equipped for 25 credits.
The Jumpack has various advantages over the Jetpack, including the ability to travel further distances in less time and being harder to hit while flying due to its faster movement. However, the jetpack allows for longer periods of flight and is better for more precise flying, making it easier to get to certain places. The slower movement of the jetpack may also help you to aim better while flying
