Compact Assault Vehicle / Wheeled PX - 10 The Compact Assault Vehicle / Wheeled PX - 10 was a single - soldier Surface Assault Vehicle manufactured by Nen - Carvon . Characteristics . The Compact Assault Vehicle / Wheeled PX - 10 was a tracked combat assault vehicle controlled by a single trooper . Measuring 5 . 1 meters , the vehicle was fast and well armored , capable of reaching speeds of 260 kilometers an hour . An extensive sensor and communications package allowed the PX - 10 to drive itself , allowing the soldier to man the blaster cannon and focus on combat operations . However , the complex computer systems employed by the PX - 10 were vulnerable to jamming . The jamming caused the input from the sensors to confuse the computers , rendering the programs governing the automated pilot assistance to not function . Armed with a single Mk 4e / S medium blaster cannon , the PX - 10 transformed a single soldier into a mobile armored assault force . Able to carry one hundred kilograms of cargo and enough consumables to last two weeks , the PX - 10 was an equal combination of weapon and fort . Restricted to military sale , PX - 10s could be bought for 25 , 000 credits on the black market . History . The PX - 10 was developed in response to the problem of spreading the Galactic Empire ' s resources too thinly across all the planets it controlled . Some remote planets were too insignificant to the Empire to warrant the deployment of a full occupational force , but still needed a significant Imperial presence . Armed with the PX - 10 , a single trooper was capable of generating the firepower of an entire squad . A number of PX - 10 equipped troopers were able to control and hold a vast amount of territory , as long as the opposition did not have firepower to match , or overcome , the local Imperial force . The Empire also used them as a surveillance tool , as well as to deny the Alliance to Restore the Republic from controlling assets due to a lack of Imperial presence . Nonetheless , Alliance forces soon came to recognize that the presence of a PX - 10 signaled a reduced Imperial presence . Imperial doctrine called for PX - 10 drivers to never leave their vehicles . Due to the known jamming issue with the onboard computers , PX - 10s were less useful against high - tech opponents who knew how to exploit the PX - 10 ' s flaw , but were effective on primitive planets throughout the Empire . The PX - 10 ' s vulnerability to sensor jamming , coupled with its limited weapons complement , meant that it never gained much traction with other organizations other than the Empire . Around 18 BBY , the Empire employed PX - 10s operated by droid pilots for patrol and surveillance on the planet Acherin . Jedi Master Obi - Wan Kenobi , Jedi Knight Ferus Olin , and Raina Quill , a member of the Acherin resistance , encountered several while attempting to reach the city of Eluthan . In 5 ABY , Luke Skywalker — along with Han Solo , Leia Organa , Chewbacca , and the Jedi Prince Ken — discovered an abandoned PX - 10 on bluff overlooking a beach on the picturesque planet Z ' trop . Skywalker and Solo deactivated the vehicle ' s weapon systems . The Hydrospeare Corporation developed an aquatic modification of the PX - 10 known as the Aquadon CAVa 400 . Fitted with lateral and stern thrusters in addition to treads , the Aquadon CAVa 400 was a submersible assault vehicle that was instrumental in the Kath subjugation .
