The following is a list of fictional Star Wars terrestrial vehicles, including armoured fighting vehicles, military aircraft, and naval ships. Vehicles appearing in the Original Trilogy All Terrain Armored Transport (AT-AT) The All Terrain Armored Transport, or walker, is a quadruped mechanized infantry combat vehicle used by the Imperial ground forces. Standing over tall with blast-impervious armour plating, these massive constructs are used as much for psychological effect as they are for tactical advantage. The AT-AT (pronounced either casually as 'at at', or using only the letters '') was first introduced in The Empire Strikes Back (as the Galactic Empire's main units against Rebel Alliance infantry during the Battle of Hoth) and also appears in Return of the Jedi (as the vehicle used to transport Luke Skywalker and Darth Vader to their shuttle on the forest moon of Endor) and in Rogue One (in the AT-ACT variant, used to respond to the attacks of Rebel infantrymen of the Rogue One unit during the Battle of Scarif, although later defeated by the arriving Rebel Red Squadron of starfighers). The also appears in a destroyed form in Star Wars: The Force Awakens, explained in the video game Star Wars Battlefront (2015) to be a residue of the Battle of Jakku, which was the Empire's last defeat and resulted in its dissolution. Modified forms appear in The Last Jedi (used by the First Order to attack Resistance forces in a former Rebel base). All Terrain Scout Transport (AT-ST) The All Terrain Scout Transport (AT-ST) is a two-legged mech walker introduced briefly in The Empire Strikes Back and featured extensively in Return of the Jedi. These vehicles were designed to screen and protect the flanks of slower moving AT-ATs and the larger tanks used by the Empire. Due to their design and movement, they are often dubbed as a "chicken walker". The name Scout Walker is also used to refer to an . This name was used for the official toy instead of the name. An AT-ST also appears briefly in Rogue One: A Star Wars Story, patrolling Jedha City following an attack by Saw Gerrera's forces. A modified AT-ST later appears in The Mandalorian under the possession of a group of raiders, as the Empire has ceased to exist by the time of the series. An updated model of the AT-ST is used by the First Order in The Last Jedi. Shortly before
