The Rebels establish Echo Base on the cold and inhospitable planet of Hoth. When an Imperial probe droid locates the base, Darth Vader’s Death Squadron arrives with AT-AT walkers, snowtroopers and scout troopers, who pour over icy landscape to attack the valiant Rebels. As large weapons blast the base, scout troopers provide mobile reinforcements for the invading stormtroopers.
