In the Star Wars fictional universe, the Imperial Navy Troopers were well trained and deadly corps assigned by the Imperial Navy to serve as guards and soldiers onboard its many Star Destroyers. They wore a black protective helmet and a black uniform. Their primary weapon was a blaster pistol. They are also known as Death Star Troopers because they first appeared in A New Hope as security guards onboard the Death Star. Besides serving the Empire as soldiers and security guards, they handled hangar control traffic, monitored sensor arrays and other duties when their combat skills were not needed. They appear in the first three Star Wars movies, A New Hope, Empire Strikes Back and the Return of the Jedi.
