All Terrain Tactical Enforcer The All Terrain Tactical Enforcer ( AT - TE ) , also referred to as a tank by clone trooper s , was a multipurpose military ground walker used by the Galactic Republic during the Clone Wars . They boasted six legs that could be magnetized , six laser cannon turrets located along the body of the walker , and a heavy projectile mass - driver cannon on top . Characteristics . The All Terrain Tactical Enforcer was a low - built vehicle that featured six articulated legs for propulsion . Its body consisted of two armored halves that were connected by a flexible concertina section , which increased the walker ' s mobility on the field . Because its legs were low to the ground , the walker had a relatively low top speed , but it also enjoyed greater stability . As its name suggests , the AT - TE was suitable for all terrains ; not only was it able able to climb sheer surfaces , but it could also survive in the vacuum of realspace . The AT - TE measured 22 . 02 meter s in length and 9 . 57 meters in height . The AT - TE ' s most powerful weapon was a single mass - driver cannon located on the vehicle ' s dorsal surface . Four smaller ball - turret laser cannons were mounted at the front , and two others at the rear . The hexapod ' s armor could easily deflect small arms fire . The AT - TE could be pierced by tanksmasher rockets , which could result in the destruction of the vehicle ' s complex propulsion mechanisms . The walker ' s pilot sat in a forward compartment , while a gunner sat exposed atop the walker to operate the mass - driver cannon . The standard version of the AT - TE carried 20 troops , and some variants carried smaller All Terrain Recon Transport s in their rear hold . Their crews were filled out by an IM - 6 medic droid , who attended to any injured clone trooper s . History . Built by Rothana Heavy Engineering , the All Terrain Tactical Enforcer became the principal battle tank of the Grand Army of the Galactic Republic during the Clone Wars . A blast from an AT - TE was Clone Commander Cody ' s chosen method in executing Jedi General Obi - Wan Kenobi when he received Order 66 , but the blast only succeeded in knocking Kenobi into water , and he later escaped to safety . Fifteen years after the end of the Clone Wars , Captain Rex , along with Commanders Wolfe and Gregor , were living in a modified AT - TE on Seelos . They , along with the Lothal Rebels , later used the tank to evade Imperial forces , which consisted of three All Terrain Armored Transport walkers . The tank was able to destroy one AT - AT in the sandstorm before Rex ordered a direct assault on the other two while the Rebels escaped . The Mass - driver cannon , unfortunately , was not strong enough to penetrate the AT - AT armor . The AT - TE was able to sustain multiple shots from both walkers before Wolfe drove it into one of the walkers . The cannon was temporarily knocked out , but Gregor was able to restore power when the rebels returned and hijacked one of the AT - ATs , giving Rex the opening to shoot the last walker in the neck . The AT - TE was destroyed when the AT - AT collapsed on it . Several AT - TEs were later modified by Rebel Alliance mechanics in order to be used as an attack vehicle during the Galactic Civil War . A number were modified with thicker armor and more powerful armament , becoming known as Elite AT - TE s . At least one AT - TE was used in the Imperial defense of the Kuat Drive Yards .
