The AT-AP (All Terrain Attack Pod) is a large Walker which is the second largest of three known walkers; the AT-ST and AT-AT. This Walker is piloted by Shocktroopers, who were elite clones with red armor. The LEGO version is expensive and comes with two rare Shocktrooper minfigures and two long-rifles for both. These Walkers were seen in Episode 3 in the Battle of Kashyyk. Not much information was released of these large tanks, but many believe that they are "special" and "rare", although this has yet to be confirmed by LEGO or LucasArts. They have three legs.
