Walker (Star Wars)

All Terrain Walkers are armored fighting vehicles from the Star Wars universe that traverse the landscape on mechanical legs. They are used by the Old Republic, the Galactic Empire, and the First Order for ground assault, reconnaissance or transport. Throughout the saga walkers have played a pivotal role in the fate of characters and the outcome of battles. Industrial Light and Magic (ILM) is responsible for their animation and design, often using models, stop-motion animation, and relevant matte paintings to depict their presence in the films.

There are a variety of walkers: The Empire Strikes Back and Return of the Jedi introduced the All Terrain Armored Transport (AT-AT) and All Terrain Scout Transport (AT-ST). Star Wars: Episode II – Attack of the Clones, Star Wars: Episode III – Revenge of the Sith and The Clone Wars introduced earlier Clone Wars-era models of walkers, such as the All-Terrain Tactical Enforcer (AT-TE), and the All Terrain Recon Transports (AT-RT). The Star Wars Legends continuity features numerous walker variants, several which have been merchandised in popular culture, while the later films Rogue One and Star Wars: The Last Jedi depicted, respectively, the former the AT-ACT variant to the standard AT-AT, the latter a restyled AT-AT for its new and more modern setting, and a new, even larger walker known as the AT-M6.

All Terrain Attack Pod (AT-AP): Featured in Revenge of the Sith and Clone Wars media, as a variation of the AT-PT. Alex Jaeger designed the AT-AP per Lucas' request to "diversify the Clone armor".[50] Nicknamed the "sniper tank", the AT-AP features a variety of artillery weapons, a retractable third leg for stability, and other offensive features.[49]

All Terrain Open Transport (AT-OT): Introduced in Revenge of the Sith and other sources, is a heavily armored transport whose open design makes it vulnerable from above. The AT-OT can transport 34 clone troopers, who are protected by thick armor and four laser cannons.[52] During the late stages of Revenge of the Sith's development, it was called the "Clone CAT walker".[53]

[51]

All Terrain Recon Transports (AT-RT): Introduced in Revenge of the Sith operated by clone troopers searching for (Frank Oz) on Kashyyyk. The AT-RT is described as a precursor to the AT-ST, though it also shares similarities to the AT-PTs of the same era.[54] A scene cut from Revenge of the Sith would have shown Yoda distracting clone troopers while Chewbacca removes them from their AT-RT in a manner similar to how he obtains control of an AT-ST in Return of the Jedi.[55] AT-RT animators studied AT-ST movement to recreate part of the "original funkiness of movement" caused by the stop-animation style used in the original trilogy.[55]

Yoda

All Terrain Defense Pod (AT-DP): Introduced in , the AT-DP is described by Star Wars references as a successor to the AT-RT, combining speed with an armored cockpit to protect a pilot and gunner. Standing 11.6 m (38 ft) high and weighing 11,200 kg (24,700 lb), the AT-DP can reach speeds of 90 km/h (56 mph). Because it is only armed with a single Kyuzo Maad-38 heavy laser cannon, the Empire primarily uses AT-DPs for defensive purposes like policing or sentry duty.[56][57][58]

Star Wars Rebels

All Terrain Mobile Artillery (AT-MA): Introduced in The Force Awakens, the AT-MA is a model of base defense walker used by the First Order to defended Starkiller Base. While it resembled the All Terrain Armored Transport once used by the Galactic Empire in terms of size and weaponry, the AT-MA was primarily designed for defense, rather than transport or assault. Several of these walkers were deployed across the planet to protect its installations, and at least three of them were present during General Armitage Hux's speech before the destruction of the Hosnian system. Several AT-MAs were portrayed in the ground vehicles storage area of a Resurgent-class Star Destroyer.[59]

quadruped

All Terrain Armored Cargo Transport (AT-ACT): Introduced in Rogue One,[61] these walkers are slightly larger than the standard AT-AT, with a hollowed-out center section that can hold a cargo container. Director Gareth Edwards instructed the film's concept artists to design walkers based on their idealized memory of the AT-AT.[62] According to background material, the AT-ACT was built for hauling cargo at Imperial construction sites and research facilities. Larger than AT-ATs at 31.9 m (105 ft) tall, an AT-ACT's central container can hold 550 m3 (19,000 cu ft) of cargo. Although not meant for use on the battlefield, the AT-ACT is heavily armored against most handheld weapons and equipped with two Taim & Bak MS-2 heavy laser cannons, allowing it to be deployed into combat in an emergency.[63][64]

[60]

All Terrain Heavy Hauler (AT-HH): Featured in The Last Jedi, utilizing many more legs than most walkers to allow it to tow heavy cargo.

All Terrain Heavy Scout (AT-HS): A model of walker fielded by the First Order. The LEGO version of the AT-HS was based on a piece of concept art for The Last Jedi which, although canon, was ultimately not used in the final cut of the film.

All Terrain Cold-weather Mobile Heavy Cannon (AT-CMHC): A remodeled variant of the Umbaran UMHC used by the Imperial Military. This prototype model was specialized in sub-zero .[65]

Merchandise[edit]

Kenner released AT-AT and AT-ST toys as part of their Empire Strikes Back line, and Hasbro released toys based on those molds when the Special Edition trilogy was distributed. Micro Machines also released AT-AT, AT-ST, and AT-TE toys.[70][71][72][73] Both Decipher Inc. and Wizards of the Coast published AT-AT and AT-ST cards for their Star Wars Customizable Card Game and Star Wars Trading Card Game, respectively.[74][75][76] Lego has released AT-AT, AT-ST, AT-DP, AT-AP, AT-OT, AT-RT, AT-TE, AT-M6, and AT-HS models.[77][78][79][80][81][82][83]
