NR-N99 Persuader-class droid enforcer

The NR-N99 Persuader-class droid enforcer, known as simply NR-N99 Tank Droids, was a model of droid tank manufactured by the Techno Union. They were primarily used by the Corporate Alliance, and were later utilized in the Separatist Droid Army during the Clone Wars.

Behind the scenes
Nicknamed the snail droid, the NR-N99 Persuader-class droid enforcer was originally planned to appear in Star Wars: Episode II Attack of the Clones during the First Battle of Geonosis and animatics of the film were made of the tanks running over clone troopers. The NR-N99 would later return for Star Wars: Episode III Revenge of the Sith, but at one point a different design was considered during the production of the film before the older design was chosen for its final appearance. For the sequences that featured the NR-N99 in Episode III, OOM pilot battle droids were put inside the tanks, suggesting that it was not an entirely automated vehicle.
