.
For The Empire Strikes Back, however, the final design was a four-legged walker. Industrial Light & Magic (ILM) created models ranging from 6 to 50 centimeters in height. ILM filmed the AT-ATs using stop-motion animation against matte paintings created by Mike Pangrazio because attempts at compositing miniature footage against live-action background footage yielded mediocre results. Additionally, ILM studied elephants to determine the best way to animate the four-legged AT-ATs. Although the stop-motion animation style gave the AT-ATs a jerky, "staccato-like" effect on film, ILM found this movement acceptable because of the AT-ATs' mechanical nature. The sound of the AT-AT walking was created by Sound Designer Ben Burtt

, by using the sound of an industrial sheet metal stamper.
A common myth is the design drew from prominent container cranes at the port of Oakland, California. Lucas denies the inspiration.

Dialog in National Public Radio's adaptation of The Empire Strikes Back states that AT-ATs "look like animals"; the character goes on to describe the vehicles as carrying "extremely heavy armor and armaments".

s. The walkers themselves carry two blasters and two laser cannons. Manufactured by Kuat Drive Yards, Expanded Universe sources describe the AT-AT as being either 15 metres (49 ft) or 22.5 metres (74 ft) tall. Their armor is resistant to most standard blaster weapons; however, the "neck" column of the walker holds no such invulnerability and, if shot, can cause the entire walker to be destroyed.
The AT-AT is the primary assault vehicle during the Battle of Hoth, first depicted in The Empire Strikes Back. In the film, the AT-ATs are responsible for destroying the shield generator protecting the Rebel headquarters, taking out many soldiers, vehicles, and installations in the process.

The case was dismissed with the court noting that not only did Seiler not produce the supposed drawings at trial, but that the copyright came one year after The Empire Strikes Back debuted.
Depiction
Star Wars guidebooks describe the AT-ST as a "reconnaissance or defensive vehicle [that] is lightweight and built for speed". Their agility allows them to defend the slower AT-ATs or support other Imperial ground forces. They are 8.6 metres (28 ft) tall (although some sources describe them at seven meters) and seat a pilot and co-pilot. AT-STs are armed with laser cannons on the "chin" and sides, feet claws for destroying small defenses and side-mounted concussion missile launchers.In The Empire Strikes Back, AT-STs scout for and support the slower AT-ATs during the Battle of Hoth. During the Battle of Endor as depicted in Return of the Jedi, the protagonists and the local Ewok tribes capture or destroy several AT-STs; their precariously balanced nature proves highly vulnerable to the Ewoks' primitive booby traps. In the Expanded Universe, AT-STs are often featured in Imperial attack forces. Video games such as Star Wars: Rogue Squadron

In addition to the AT-TE, other vehicles were created for Clone Wars media and depicted as predecessors to the walkers featured in the original trilogy. One such walker is the two-legged All Terrain Attack Pod (AT-AP), a variation of the AT-PT, seen in Revenge of the Sith and Clone Wars media. Alex Jaeger designed the AT-AP per Lucas' request to "diversify the Clone armor". The AT-AP features a variety of artillery weapons, a retractable third leg for stability, and other offensive features.The All Terrain Open Transport (AT-OT), also seen in Revenge of the Sith and other sources, is a heavily armored transport whose open design makes it vulnerable from above.

in Revenge of the Sith. 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. 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. 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.
