K-3PO was a 3PO unit protocol droid who served the Alliance to Restore the Republic during the Galactic Civil War against the Galactic Empire. The droid's memory banks were full of battle tactics, and so during the Battle of Hoth K-3PO aided with the command of Rebel forces from the command center of Echo Base. The protocol droid was destroyed when the base sustained damage from Imperial fire. K-3PO had yellow sensors and white plating.
