The elite soldiers used by the Galactic Empire and later the First Order in the Star Wars universe.
The Stormtrooper Corps of the Galactic Empire was an elite branch of the Imperial Army. Its members were distinctive in their white armor which covered their entire bodies, including their faces. Depending on the battlefield environment and/or their assigned tasks, stormtroopers were sometimes equipped with specialized armor (examples include snowtroopers and scout troopers).
Later, the First Order used its own stormtroopers which were inspired by the stormtroopers of the Galactic Empire. The First Order's stormtroopers also wore distinctive white armor.
