[1] AT-AT pilots receive specialized training in order to operate their walkers, using terrain sensors in the head and footpads to find sure footing, and as such warrant extra layers of protection and long-lasting power packs in their life-support suits.

[12] During the battle, the AT-AT designated Blizzard Two is destroyed when Wedge Antilles and Wes Janson use their snowspeeder's tow cable to trip it up and target its now-exposed neck with blaster fire to blow it up.

[12][10] Luke Skywalker destroys another AT-AT, Blizzard Four, by using a magnetic grapple to reach its underbelly, cut open a hole with his lightsaber and throw in a grenade.

[12][10] Ultimately the Empire is victorious as General Veers' Blizzard One destroys the shield generator, and in the ensuing rout he orders the remaining AT-ATs and AT-STs to overrun the Rebels' trenches and capture as many as possible.

Using scavenged parts from the walker and other vehicles, Rey is able to construct a power system for her home along with booby traps and motion sensors to deter potential thieves.

Information in the AT-AT's manifest reveal it was designated Hellhound Two, part of the complement of the Imperial-class Star Destroyer Interrogator, but the ultimate fate of its crew is unknown.

[18][19] Dr. Malcolm Davis, director of the Defense & Strategy Program at the Australian Strategic Policy Institute, argues that the AT-AT has several flaws which make it an ineffective design.

[22] 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.

Video games such as Star Wars: Rogue Squadron and Shadows of the Empire (in a much expanded Battle of Hoth) include numerous AT-STs, and these can be destroyed by direct shooting from the player's craft, in contrast to the heavily armored AT-ATs which have to be tripped by tow cables.

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.

[25] Constructed as a companion to the larger AT-AT, the scout walker's lightweight bipedal design allows it to travel across rugged ground and fulfill a variety of missions, including patrolling, reconnaissance and mop-up operations.

[23][29] A powerful gyro stabilizer, sophisticated shock absorbers, and terrain-measuring sensors in the footpads allow the scout walker to move faster and traverse areas which would be impassible to an AT-AT.

[23] In The Empire Strikes Back, AT-STs scout for and provide support for the slower AT-ATs during the Battle of Hoth; when the shield generator is destroyed, they race ahead of the assault walkers to capture as many of the fleeing Rebels as possible.

Another is hijacked thanks to Chewbacca climbing aboard and using his strength to rip open its roof hatch; he proceeds to turn its weapons against the other AT-STs to help win the battle.

[15] In episode 208 of Mythbusters, the Build Team (Grant Imahara, Kari Byron and Tory Belleci) tested the plausibility of the scene in Return of the Jedi wherein a swinging log trap destroyed an AT-ST.

The team determined that the logs in the scene each weighed approximately 10,000 lb (4,500 kg) and were swung at a 45 degree angle at the walker, impacting with the energy equivalent of around two megajoules.

[34] Their in-universe manufacturer is Rothana Heavy Engineering, a subsidiary of Kuat Drive Yards and long-time enemy to the Trade Federation and Techno Union.

[32][34] A turret-mounted mass driver cannon atop the AT-TE has a low rate of fire but can be used to bombard fixed emplacements or shoot down slow-moving aircraft.

[31][34] The AT-TE's conductive armor spreads heat to minimize penetration from enemy fire, and is well-shielded against electromagnetic pulse and ion cannon weapons.

[31] In the Star Wars Rebels episode "Relics of the Old Republic", a heavily customized AT-TE is used by clone troopers Rex, Wolffe and Gregor as a mobile residence on the planet Seelos.

Modifications made to the walker include renovating the interior to make room for bunk beds and a kitchen, and replacing the main cannon with rod and reel for catching the planet's wildlife.

While acknowledging the AT-TE's better stability and maneuverability, he cites the AT-AT's more powerful weaponry, impenetrable armoring, and greater carrying capacity as making it the definitive Star Wars walker.

Built around a massive turbolaser cannon carried on its back, this simian-shaped walker combines equal parts devastating firepower and psychological warfare.

[42] In making a new walker vehicle based on the AT-AT for the First Order, the creative team behind The Last Jedi wanted to address the tow-cable vulnerability which had been highlighted in The Empire Strikes Back.

Capable of penetrating deflector shields rated to withstand planetary bombardments, the weapon requires a dedicated power plant and several auxiliary fuel cells to reduce recharge time.

The AT-M6's heavily armored front legs were modified to handle the weight and massive recoil of firing the weapon, and feature ventilation gates which double as cable-cutters.

This locomotion system also gives the walker the appearance of a giant simian predator which, combined with firepower to rival a battleship, is meant to help intimidate an opponent into submission.

[41][44][45] With the Resistance entrenched on Crait at a former Rebellion base, a contingent of AT-M6s are among the First Order forces deployed to the planet's surface to engage them, providing escort for a massive superlaser siege cannon.

[44][46] In comparing the AT-M6 to its predecessor, Dr. Malcolm Davis notes that, while the specific vulnerability to tow-cable attacks was addressed, many of the same criticisms applied to the AT-AT still hold true for the First Order's walker.

He argues it was a lost opportunity to not give the walker the same agility as its simian inspiration and allow it to use its massive arms to walk, climb and swing more easily over obstacles.
