Vintage Imperial Attack Base

The Imperial Attack Base Playset is a simple yet effective toy, which provided kids with a suitable environment in which to act out Hoth snow battles. It incorporates several rather tame action features, including a combination bunker-ice bridge, which collapsed when a trigger was activated. While this is a very cool playset it doesn't make sense because the Empire does not have a base on Hoth, the Rebels do. So, shouldn't it be called the Rebel Attack Base? Whatever, the playset is something I got for Krismas in 1981 and it's been in my collection ever since.
