All Terrain Scout Transport

The All Terrain Scout Transport (AT-ST), also known as a Scout Transport, Scout Walker, also nicknamed a chicken walker. was a lightweight, bipedal walker used by the ground forces of the Galactic Empire. Later, the First Order used an updated variant of the AT-ST within their military.
==Characteristics==
The All Terrain Scout Transport (abbreviated to AT-ST) was a scout and reconnaissance light walker of the Galactic Empire's All-terrain vehicle line. It consisted of an armored command and control cabin mounted on two gyro-stabilized legs and was utilized for battle line support, antipersonnel hunting and troop support. They were also commonly used to screen the flanks of larger assault walkers for major ground operations, during which they supported heavier walkers such as AT-ATs by eliminating pockets of resistance and clearing out denser terrain such as small canyons and cities along the path of a planned invasion route.Star Wars Character Encyclopedia: Updated and Expanded
The command cabin featured two armored viewports which were deliberately set to give any viewer the unsettling sensation of staring into the face of a soulless beast or oversized combat droid, despite not actually being needed due to the AT-STs extensive sensor package. Inside the control cabin, the command module featured multiple holoprojectors which displayed a holographic 360-degree view of the combat zone. The cabin (or "head") itself was capable of rotating 240 degrees side to side, greatly benefiting the gunner's target-acquisition abilities and capabilities for destruction. A cooling system was equipped above the command module behind the entry hatch.
===Armament, power, and defense===
AT-STs were equipped with two chin-mounted MS-4 twin blaster cannons with a range of two kilometers. They also featured one cheek-mounted 88i twin light blaster cannon and one cheek-mounted DW-3 concussion grenade launcher capable of doing massive damage to enemy vehicles and ground troops at close range and used at dealing with large amounts of infantry as well as mounted turrets that were too risky to be taken out with rocket launchers. AT-STs were also equipped with retractable footpad blades which could slash apart wires and fences at ground level. The modular design of the All Terrain Scout Transport allowed for ease in customizing the walker with armaments and tools for specific mission parameters, including mortar launchers that could be attached to the command pod of the AT-ST.
Several areas of the walker's hull were reinforced with armored plates, including the rear of the command cabin which featured the weapon power converters, the front (or "face"), the joints and the gyro-stabilizing system. In addition, reinforced armor plates enveloped the control cabin, protecting the two-person crew from small-arms fire, but not laser cannons, missiles, or other heavy ordnance.
Due to its small size, the AT-ST could not be equipped with an onboard full power generator, and as such relied on eight disposable high-intensity power cells mounted directly at its drive engine. Two more cells powered the cabin gyro for redundancy. Despite covering the walker's high energy needs, these power cells greatly limited its range.
===Locomotion and navigation systems===
The walker's deceptively rickety gait belied a potent patrol vehicle. Gyros and flexible joints formed a complex system that controlled balance and stabilized the walker across a variety of terrains. Sophisticated shock-absorbers built inside the lower legs of the walker kept it stable at all times, while a variety of sensors built within its footpads offered detailed feedback on the terrain the AT-ST was moving through, reading intensity and contour for precise foot placement. The locomotion computer mounted in the command cabin could take control of the walker and use the information relayed from the sensors to drive it autonomously over even ground, although an experienced pilot was still needed over complex terrain.
===Performance===
Despite its speed and agility, an AT-ST walker's offensive and defensive power were significantly compromised. Offensively, its weapons systems were only good against lightly armored targets at close range. Defensively, its lighter armor could repel attacks from small-arms fire, but not laser cannons, missiles, or other heavy ordnance. Its armor did not cover its entire frame, lest the walker lose its agility. Striking the walker's unprotected gyros underneath the command module could destabilize the walker and cause it to fall. Additionally, deep trenches or cable lines leveled at the height of the AT-ST's ankles and knees could cause it to trip and topple the vehicle. AT-STs are also known to require constant maintenance, having perhaps the highest maintenance-per-hour record in the entire Imperial Army.
The Ewoks of Endor discovered that the AT-STs were vulnerable to anti-Gorax traps. Ramming logs could smash through the walker's head, destroying the cockpit. One of its other weaknesses was its susceptibility to hijacking, despite the height of the vehicle seemingly making hijacking an impossibility. A sufficiently strong force could rip the entrance hatch off the top of the walker. If commandeered, the walker's cannons could easily penetrate other AT-STs' armor.
==Variant models==

The All Terrain Heavy Scout was a highly evolved variant of the First Order AT-ST, which saw service in the First Order Army during the intergalactic First Order-Resistance War.Star Wars: The Last Jedi: The Visual Dictionary
==History==
Part of the All-Terrain walker family, the AT-ST was better equipped than the Republic AT-RT and was in service by the Invasion of Mon Cala in 18 BBY.Darth Vader (2017) 14 The toes for the walker's feet were manufactured by convicts in the Jubilar penal work camp.Star Wars: The Rise and Fall of the Galactic Empire
In 14 BBY,Star Wars: Timelines dates the events of Star Wars Jedi: Fallen Order to 14 BBY. an AT-ST attacked the Stinger Mantis ship on Zeffo, but was destroyed by the Jedi Padawan Cal Kestis. The Empire used AT-STs against the Partisans led by Saw Gerrera on Kashyyyk and Kestis, who helped the rebel group during the battle to take over an imperial refinery. The AT-STs were on Ilum when the Empire started mining the world to acquire Kyber crystals. When Kestis went to the planet to find a crystal to build a new lightsaber, two AT-STs were destroyed by the Padawan during his escape from the world.Star Wars Jedi: Fallen Order
The Imperial Military commonly used the AT-ST in a variety of environments.Rogue One: A Star Wars Story After rebel leader Saw Gerrera and his Partisans took to defending the world of Jedha, AT-STs were among the reinforcements deployed to aid the planet's occupying garrison; with the ancient Holy City consumed by surface warfare, the AT-STs were fielded for urban pacification against the Partisans whenever they could fit into the city's winding and narrow streets. While accordingly impractical during the Jedha insurgency, the walkers were also fielded to try to send a message beyond their blaster fire, but the Partisans instead chose to intensify their efforts against the garrison. With the Empire retaliating in equal force, battle continued in the streets, with AT-STs devastating the city and civilians. Even so, both sides continued to fight, with one AT-ST being deployed in Tythoni Square as part of the battle on Jedha in 1 BBY.The battle on Jedha took place during Rogue One: A Star Wars Story, which Star Wars: Timelines dates to 1 BBY. The insurgency ended when all but at least three percent of the Imperial garrison retreated under Protocol 13. Afterward, the DS-1 Death Star Mobile Battle Station destroyed the Holy City.Rogue One: A Star Wars Story novelization
The walkers were also used in the Galactic Civil War. At least one fought in the Battle of Allst Prime. General Weiss commanded a customized AT-ST. Between the Battle of Yavin and Battle of Hoth, the Alliance to Restore the Republic operated stolen AT-STs, and provided them to Saponza's Gang, who often fought against the walkers. Three AT-STs were deployed as part of Lieutenant-Inspector Magna Tolvan's attack on the Son-tuul Pride crime syndicate.Doctor Aphra (2016) 19 Several fought alongside All Terrain Armored Transports (AT-ATs) at the Battle of Hoth. They also notably participated in the Battle of Endor, where they were defeated by the Ewoks and their anti-GoraxStar Wars: Absolutely Everything You Need to Know traps. One walker, Tempest Scout 2, was captured by the rebel Wookiee Chewbacca and two Ewoks, Widdle Warrick and Wunka.Return of the Jedi: Beware the Power of the Dark Side!
AT-STs were constructed in a weapons depot the Empire kept in operation on the world of Sullust, which was able to remain in operation despite the planet's liberation. Infiltrating and destroying the factory, New Republic General Landonis Balthazar Calrissian and soldier Shriv Suurgav escaped aboard an AT-ST. The factory's destruction robbed the Empire of additional equipment it was awaiting on the planet Jakku. Nonetheless, a number of AT-STs the Empire still had its disposal were used in the ensuing final battle of the Galactic Civil War, the Battle of Jakku, which ended up being an overwhelming victory for the New Republic.Aftermath: Empire's End In 9 ABY, an AT-ST was used by looters to attack a village on the planet Sorgan. The AT-ST became embroiled in the battle between the looters and the village people, who were suddenly led by Mandalorian bounty hunter Din Djarin and former rebel shock trooper Cara Dune. In the end, Djarin destroyed the walker with a grav charge.
Thirty years after the close of the Galactic Civil War, a splinter military group of the New Republic called the Resistance utilized old Imperial AT-STs in combat against the reorganized remnants of the Galactic Empire, the First Order. They possessed an orange repaint and were crested with the Resistance starbird.
==Behind the scenes==
All Terrain Scout Transports first appeared in the 1980 motion picture Star Wars: Episode V The Empire Strikes Back. The AT-ST model received some cosmetic changes for its extensive appearance in the 1983 film Star Wars: Episode VI Return of the Jedi, thus explaining the minor differences in the models used for the two films.
