The Techno Union's droid army was first mentioned in Star Wars: Episode II Attack of the Clones. ĭuring the closing stages of the Separatist Crisis, Foreman Wat Tambor pledged his loyalty and droids Confederacy of Independent Systems, integrating its droid army into the Separatist Droid Army. Kenobi initially assumed the Union was behind the kidnapping, though Skywalker and him would ultimately learn it was a test. The droids were later used in a staged kidnapping of Grand Master Yoda, which was part of a test for Jedi Knight Obi-Wan Kenobi and Padawan Anakin Skywalker. Though the Jedi Order recovered the droids, at least several of which were B1-series battle droids, the Union was told that the units were now property of the Galactic Republic after they petitioned the Jedi Council for their return.
The Union was also a droid producer, but, two years prior to the rescue of Yoda, a batch of their battle droids were stolen by Chagrian smugglers. The Techno Union maintained an army of battle droids. ' The Techno Union army is at your disposal, Count.' ―Wat Tambor to Count Dooku
