NR-N99 Persuader-class droid enforcer/Legends

The Tank Droid is a war vehicle from the fictional Star Wars constructed by the Corporate Alliance to combat the Army of the Republic. It was one of the many contributions of the Corporate Alliance to the droid armies of the Confederacy of Independent Systems. The tankdroid was a 3 metre tall automaton with a huge central wheel supported by 4 small outrigger wheels. It could also roll on its single traction drive thread. The tank droid was also equipped with 4 arm-mounted blaster cannons. The droid's front featured several sensors above its two photoreceptor eyes. During the Clone Wars, the tank droid was dispatched across the Star Wars galaxy to defend Confederacy bases. During a battle the tank droid could also crush to death any unfortunate enemy soldier that got into its path with its huge central wheel.

They appeared in the Revenge of the Sith during the Battle of Kashyyyk where they crushed countless Clone troopers and Wookies.
