The TIE Mauler, more formally known as the TIE ap-1, is an Imperial ground vehicle used during the early years of the Galactic Civil War.
The TIE Mauler is built around a standard TIE/ln starfighter cockpit, fixed between a pair of tank treads instead of wings. As with its airborne brethren, the Mauler emphasizes speed and maneuverability at the expense of the protection of armor and deflector shields. Because of their vulnerability to concentrated fire, these vehicles are often deployed in groups of five.
Although TIE Maulers are armed with three rapid fire blaster cannons, the drivers of these vehicles soon discovered that the vehicles' treads were also effective weapons against enemy troops. Gruesome displays of this vehicle running over Rebel soldiers earned it its nickname: Mauler. These tanks are also equipped with a self-destruct device that can be activated in an emergency.
