The IG-227 Hailfire Droid was an unit of Battle Droid used by the Confederacy of Independent Systems during the Clone Wars. All of the Hailfire Droid units would then be deactivated by order of the newly formed Galactic Empire in order to eliminate the Separatist threat. Most of the hailfire droids on the planet Kashyyyk were reprogramed by rebellious Wookie Warriors to fight the Imperial Clone Troopers on the planet. Several years later, the Alliance to Restore the Republic found a large supply of IG-227 Hailfire droids and reprogrammed them to fight against the Empire on several rebel occupied planets. The Rebel Hailfire Droids would be repainted silver and red to show their affliction, and to make them stand out from the standard brown hailfire units from the Clone Wars. Hailfire droids are some of the only battle droid/Former Separatist units in the Rebel Alliance, alongside a few B1 Battle Droids, various models of Destroyer Droids, and the AAT.
