AT-AT Swimmer
a version of the Imperial walker that was used in aquatic environments, the All-Terrain Aquatic Transport was designed with the main section of the body expanded and flattened out in order to accommodate the addition of repulsor engines that helped keep it afloat. The Swimmer was heavily armored and protected from the effects of salt and water, and resembled a huge turtle. It required a crew of five, and could transport up to 40 troops and 600 kilograms of cargo. It was armed with a pair of modified heavy laser cannons which could fire underwater, and a pair of medium blasters.
