"Move out!"- An AAT Droid
The Armored Assault Tank Droid was an green and yellow painted Battle Droid that was programmed to pilot Armored Assault Tanks, or AATs, and use them in battle. They could also be used as scouts on jungle planets like Dantooine, due to their camoflauged paint job. However, like all B1-Battle Droids and the rest of the Separatist Droid Army, these units were shut down at the end of the Clone Wars, but would later be used in 1 ABY when the Galactic Empire started making their own improved models of AATs to fight the Alliance to restore the Republic.
