Blizzard Four

Blizzard Four was the name of a AT-AT walker during the Battle of Hoth. It was commanded by Colonel Starck.

In an attempt to impress Darth Vader, Starck and his group went through the treacherous Kerane Valley. Later in the battle, Luke Skywalker, his X-Wing crippled and crashed, narrowly dodged Starck's AT-AT's crushing foot, before grappling to it's belly and using a thermal detonator to destroy it.
