Clone cold assault troopers and the 21st Nova Corps fought during the Clone Wars in frigid environments such as Orto Plutonia, Rhen Var, and Toola. Specialized types of snowtroopers included Snowtrooper Scouts, Heavy Snowtroopers, and Arctic Jumptroopers.
When the Empire located the Alliance to Restore the Republic's base on Hoth three years after the Battle of Yavin, the elite Blizzard Force, led by General Maximilian Veers, were involved in the Battle of Hoth that would later become a major Imperial victory and a major blow for the Rebel Alliance.
Snowtrooper armor was well insulated to protect against extreme cold, with a suit and heated breather mask powered by a battery pack that could last up to two standard weeks. For greater survivability, it also included ice boots, an insulated belt kama, polarized snow goggles, grappling hooks, ion flares, and a homing beacon. Snowtroopers were often equipped with E-11 blaster rifles and E-Web heavy repeating blaster cannons. Some could be trained to handle either flamethrowers or T-7 ion disruptor rifles.
