Imperial Army officers and soldiers of a legion, as seen during their deployment to the Battle of Endor.
Within an army, a legion served as a ground infantry formation. During the Clone Wars, the 501st Legion was one such unit in the Grand Army of the Republic. The Droid Army of the Confederacy of Independent Systems also made use of legions, with Commander Riff Tamson in command of a legion composed of aqua droids. A legion in the Stormtrooper Corps was made up of four regiments, for a total of 12,800 stormtroopers. To safeguard the shield generator for the second Death Star, Galactic Emperor Sheev Palpatine positioned Tempest Force, a complete legion of his most elite troops, on the forest moon of Endor. During the Battle of Endor, this legion fought against Rebel Alliance forces and the indigenous Ewok warriors. The First Order organized their stormtroopers into legions of 8,000 troopers. A complete legion was stationed aboard the Resurgent-class Star Destroyer called the Finalizer. The Sith Eternal divided their Sith troopers into legions consisting of 5,000 soldiers, with each legion named in honor of an ancient Sith Lord.
