Once a heroic Jedi Knight, Darth Vader was seduced by the dark side of the Force, became a Sith Lord, and led the Empire’s eradication of the Jedi Order. He remained in service of the Emperor -- the evil Darth Sidious -- for decades, enforcing his Master’s will and seeking to crush the fledgling Rebel Alliance. But there was still good in him…
Stormtroopers are elite shock troops fanatically loyal to the Empire and impossible to sway from the Imperial cause. They wear imposing white armor, which offers a wide range of survival equipment and temperature controls to allow the soldiers to survive in almost any environment. Stormtroopers wield blaster rifles and pistols with great skill, and attack in hordes to overwhelm their enemies. Along with standard stormtroopers, the Empire has organized several specialized units, including snowtroopers and scout troopers.
When stationed on Hoth, the Rebel Alliance modified T-47 airspeeders to become snowspeeders, fast flying conveyances for patrol and defense of their hidden base. It took some doing to keep the crippling cold from permanently grounding their airforce, but Rebel ingenuity overcame the relentless Hoth elements. The T-47 airspeeder is a small, wedge-shaped craft with two forward-facing laser cannons. In its rear arc is a harpoon gun fitted with a heavy-duty tow cable. The snowspeeder is a two-man vessel, with a pilot and rear-facing tailgunner.
The All Terrain Armored Transport, or AT-AT walker, is a four-legged transport and combat vehicle used by the Imperial ground forces. Standing over 20 meters tall with blast-impervious armor plating, these massive constructs are used as much for psychological effect as they are for tactical advantage.
While not as imposing as its larger AT-AT walker cousin, the AT-ST nonetheless served as a significant addition to the Imperial side of battlefields in the Galactic Civil War. The two-man craft is lightly armed with chin-mounted laser cannons, and side-mounted weapon pods. The two-legged transport, dubbed the scout walker by many, serves as a reconnaisance and patrol vehicle, often flanking approaching AT-ATs and mopping up infantry that sneaks past the larger walkers. The Imperials used AT-STs in both the Battle of Hoth and the Battle of Endor.
