Jumptroopers, also known as Rocket Troopers, were specialized Stormtroopers equipped with Jetpacks and breathing apparatuses.
A contingent of Jumptroopers were attached to Captain Brunson's Imperial Light Cruiser. These Jumptroopers attempted to board the Ghost Crews' ship, the Ghost but were repelled by the rebels, Captain Rex, and Saw Gerrera. After the entire unit was killed, Brunson ordered her crew to bury the Ghost by collapsing an air shaft on top of them. Several Jumptroopers were also aboard one of the Interdictor Cruisers that joined the Seventh Fleet for the Battle of Atollon, and engaged Ezra Bridger and the Mandalorian Warriors of Clan Wren when they attacked the ship.
