The Galactic Empire's troopers known as Darth Vader's Security Force were an elite unit. They appeared the same as snowtroopers and Vader's Special Force Trooper, but their armor was red instead of the standard white. During the Occupation of Bespin, Darth Vader commanded both the Security Force and the Special Force Troopers. They were equipped with shields, grenades, and the E-Web heavy repeating blaster, with their shields bearing resemblance to those used by grenadier troopers.
