Incinerator tanks, also known as Imperial Armored Assault Tanks, were provided by the Galactic Empire to Trandoshan hunting groups. These tanks were deployed on the planet of Kashyyyk with the express purpose of clearing expansive areas of the jungle and eradicating Wookiee settlements.
These Imperial Armored Assault Tanks represented an enhanced, more formidable version of the Confederate AAT. Instead of laser cannons, they were armed with flamethrowers. Furthermore, they featured an additional anti-personnel weapon on each flank, an extended rear bumper, and an extra external seat behind the commander's hatch for a turret gunner.
Around 19 BBY, in the initial phases of the Pacification of Kashyyyk, the Galactic Empire sought the assistance of Trandoshan mercenaries to aid in clearing the planet's extensive jungles. Equipped with Imperial Armored Assault Tanks, the Trandoshans commenced the burning of vast jungle regions to facilitate Imperial industrial development.
Shortly after this operation commenced, Clone Force 99, accompanied by Gungi, a renegade Jedi Padawan, arrived on Kashyyyk. Their mission was to return the young Wookiee to his people. After discovering a devastated Wookiee village, the group encountered a small convoy consisting of two Imperial Armored Assault Tanks and Trandoshan mercenaries, who were escorting a bound Wookiee warrior. The team swiftly eliminated the Trandoshans and the two Imperial tanks, successfully liberating the Wookiee prisoner before making their escape.
Soon after, a larger convoy, including Imperial Armored Assault Tanks, clone stormtroopers, and Trandoshans under the leadership of Commander Babwa Venomor, arrived at the site of the earlier conflict. Observing the lightsaber marks on the destroyed tanks, the clones suggested reporting the presence of a Jedi to Imperial command. However, Venomor insisted that he and his mercenaries could eliminate the Jedi themselves.
The entire convoy, along with all its tanks, was subsequently ambushed and destroyed due to the combined efforts of Clone Force 99 and Wookiee fighters.
