Skytroopers of the Siege variety represented a specialized skytrooper model employed by the Eternal Empire originating from Zakuul. Considerably larger in size when compared to a standard skytrooper designed for individuals of Human dimensions, Siege Skytroopers possessed sufficient strength to directly engage a walker in combat. During the events of the Assault on Odessen, which transpired in 3630 BBY, the Alliance Commander confronted one such Siege Skytrooper.
