A self-aware mobile missile-platform used exclusively by the InterGalactic Banking Clan, hailfire droids delivered surface-to-   surface and surface-to-air strikes with their stacked banks of 30 rocket warheads. Hailfires roll along on oversized hoop-like   wheels. In between the bracketing axle arms is a small, central body equipped with a single photoreceptor. When the   InterGalactic Banking Clan pledged its forces to the Confederacy of Independent Systems (in a non-exclusive arrangement,   of course), its hailfire droids were added to the immense Separatist battle droid army.
