In the fictional Star Wars, the Armoured Assault Tank or AAT is a large repulsor tank used mainly by the Trade Federation in the Star Wars universe. It was first seen in Star Wars Episode I: The Phantom Menace. It also appears in several video games, such as Clone Wars, Battlefront, Battle for Naboo, and Phantom Menace. The vehicle was designed by Baktoid Armor factories, with most important parts in the back. It carries a payload of 55 missiles, but once it runs out, it must return to its carrier to have its bottom replaced with a new one. Its crew are 4 battle droids (commander,pilot,2 gunners). While relatively quick, it is sluggish compared to Gian and Flash speeders.

The AAT continued to see action in the Clone Wars fighting on a multitude of worlds, including Muunilinst. Here, one such tank was highjacked and destroyed by an ARC Trooper on a covert mission deep within the Muunilinst capitol.
