Jumptrooper

Imperial Jumptroopers, the direct successor of the the Republic Clone Jet Troopers, are an air-to-ground attack unit that is trained to engage airborne, entrenched, or otherwise inaccessible enemies. They are also trained in the use of hit-and-run attacks in which they ambush the enemy from above. They often provide Stormtrooper units with air cover during pitched battles. They are the primary Imperial unit designated to "keep order" on low gravity worlds or on atmospheric platforms such as Cloud City. =Equipment= They are equipped with an AJP-400 Hush-About Personal Jet Pack that allows them to burst through the air in short spurts of about 20 seconds and to hover over a location for an extended period of time. There is, however, the danger of the jetpacks exploding if they are struck by an attack such as Force Lightning. In addition to this, they are armed with DN Bolt Casters - plasma disruptors which are far more powerful than standard Imperial-issued weaponry and noted for a lack of recoil when fired. This allows the Jumptroopers to discharge the weapon without any fear of changing their flight path or being knocked off balance while flying. Besides this, they are occasionally outfitted with rocket launchers, heavy blaster rifles, rail detonators, as well as flamethrowers which they discharge when at close range to their enemies. To give an added punch, the jumptroopers also have an integrated Merr-Sonn Missile System in their jet packs. =Sources=
