TIE Crawlers (also called Century Tanks) were Imperial heavy tanks, employed primarily by the Imperial Remnant after the collapse of the Empire. Their predecessors were the TIE Maulers. TIE Crawlers were also utilized by the Confederation during the Second Galactic Civil War. They were armed with one light and two medium laser cannons, and held one pilot. It featured the standard TIE ball cockpit with large tank treads attached on either side. A slender tail section featured multiple power cells, similar to those used in the AT-ST. The energy compliment powered the tank, the medium blasters, and a light turbolaser turret underneath the cockpit. This vehicle could achieve speeds of up to 90 km/h. 7664 TIE Crawler is a Star Wars Expanded Universe set released in 2007 with 548 parts.
