IG-226 Hailfire tank

The IG-226 Hailfire tank, also known as a wheel tank was a modified version of the Hailfire droid constructed by Haor Chall Engineering for the Intergalactic Banking Clan during the Clone Wars. It was highly effective against heavy enemy defenses.

Characteristics
The Hailfire-tank was a mobile missile platform capable of eliminating platoons of soldiers and destroying enemy tanks. Piloted by an Pilot battle droid, the Hailfire-tank runs on its hooped, large pair of wheels on the sides of the central cockpit, which could run on any terrain.

On the sides of the cockpit, the Hailfire-tank is equipped with two missile ranks with 15 guided rocket warheads capable of taking out Republic tanks and walkers with one precise shot. They also had a double laser cannon used to take down enemy troops and weaken walkers.

History
These modified Hailfire-droids made their debut in the Clone Wars during the Battle of Geonosis destroying many AT-TEs and killing countless clone troopers before being destroyed by Republic gunships.

Along with their droid counterparts, they were retired due to missile problems. They were later used again after the Banking Clan came up with air mobile refresh droids, which were partnered up with Hailfire-tanks to refresh their ammo. At the end of the war, these tanks were taken by the Corporate Sector for their defenses.
