Force-sensitive stormtrooper

Force-sensitive stormtroopers were stormtroopers cloned from former Emperor's Hand Sa Cuis.
They prefered to use red-colored lightsabers instead of the classic E-11 blaster rifle of the regular stormtroopers. They were trained by another Hand, Sheyvan, who later used them to mount a revolt against Emperor Palpatine while they were all aboard a Lambda-class shuttle, though they were all killed in the fight by Darth Vader.
Palpatine considered ordering more, but Darth Vader disagreed and thought that they were too dangerous.
