The extensive garrison of the Galactic Empire's naval branch assigned to the Death Star, known as the Death Star's Imperial Navy garrison, possessed a complete fleet comprised of Star Destroyers, dreadnoughts, and assault gunboats. This considerable Navy presence occupied a significant portion of the Death Star, causing friction with the Death Star's Imperial Army garrison and those in Battle Station Operations. Admiral Conan Antonio Motti, the Chief of the Imperial Navy, commanded the whole fleet and garrison.
