The Rebel Shield Generator is a structure found on the icy, snow covered planet of Hoth. This is an objective that the Rebels must protect from the Imperials. The Shield Generator also functions as a command post, however, once destroyed it cannot spawn anymore units. It is also the objective that the Empire must destroy, in order to win a mission in campaign mode. In the campaign mission Our Finest Hour, you are required to destroy it before entering Echo Base. This is to bring down the shields so that you can move in and destroy the Rebel Transports. Near the Generator are trenches lined with two Hoth Dish Turrets and two Hoth Defence Turrets , along with a couple of Health Droids and Ammo Droids.
