IG-227 Hailfire-class droid tank

The IG-227 Hailfire-class droid tank, commonly known simply as the hailfire droid, was a model of droid tank manufactured by Haor Chall Engineering that was used by the InterGalactic Banking Clan and Confederacy of Independent Systems during the Clone Wars and the Alliance to Restore the Republic during the Galactic Civil War.

Description
A model of droid tank, the IG-227 Hailfire-class droid tank had light armor that allowed it to enter the battlefield at very high speeds using its large hoop wheels at the cost of making it vulnerable to infantry attacks. A red photoreceptor in the middle section of the droid could lock on to both land and air vehicles from an impressive distance, giving the missiles a far reach. These projectiles were effective against stationary or slow-moving targets on terrain where blaster weapons were unusable due to a lack of clear lines of sight, and one was enough to destroy an LAAT gunship or an All Terrain Tactical Enforcer. The missiles were most effective at ranges less than a kilometer and followed deliberately swerving, evasive trajectories, and when they were depleted, a hailfire droid was forced to rely upon its twin chin-mounted blasters.

History
Manufactured by Haor Chall Engineering, the hailfire droid was originally commissioned for construction by the InterGalactic Banking Clan for the intended purpose of debt collection. During the Separatist Crisis, the Banking Clan dedicated its resources to the Confederacy of Independent Systems, and their hailfire droids fought as part of the Separatist Droid Army during the Battle of Geonosis, the opening battle of the Clone Wars, where 4,100 units were deployed, continued to see use in battles up until at least nine months into the conflict, including one on Murkhana. However, despite its powerful prescience on the battlefield, the hailfire droid's use was short-lived because they carried a limited amount of missiles. During the Galactic Civil War, they were adapted by the Alliance to Restore the Republic with weaponry capable of destroying turrets as well as vehicles.
