A-13 patrol droid

A-13 patrol droids, were small droids built and deployed on Tatooine by the Chiss during and after the Skirmish at Carkoon, to patrol the deserts in search of any left over Sith that had escaped from the battle. They were equiped with small blasters in their base, and had advanced optical technologies integrated into their visual sensors. The Chiss also used them on their stations and bunkers, as a means of security.
