Shadowtrooper
this was the name of the elite stormtrooper unit which specialized in undercover, special-forces type operations. Also known as Storm Commandos, these forces were initially trained by Crix Madine, before he defected to the Alliance. The shadowtroopers, however, were considered very useful by the Emperor himself, and remained as a part of the military structure. Like Alliance SpecForce troops, the Shadowtroopers were used to infiltrate secure areas and break open stalemated situations. Shadowtroopers remained part of the Imperial military for many years following the Battle of Endor.
