The Jump Trooper is an Imperial soldier found on Kamino, Felucia, the Jedi Temple, and many other places. They use jet packs and can shoot a little more faster than regular troopers. They attack with a blaster rifle and maybe a flamthrower. If you use Force Lightning it can make them go closer to ground and disable their jetpacks for a little bit. Use your lightsaber to destroy them while they are down. They are seen in many othe locations in both the Force Unleashed I and II.
