Snowtrooper
From Lego Star Wars Wiki
Snowtroopers are Imperial stormtroopers trained to operate in very low temperatures. They were equipped with heaters in their masks, backpacks and chest plates to help keep them warm and making it possible for them to operate under extreme cold conditions. Snowtroopers can survive for two weeks alone on their suit's battery power. They were used to attack the Rebel base on Hoth.
