IG-88's Droid Army was a large droid army under the command of the IG assassin droids IG-88A, B, C, and D and 3D-4X before and during the time of the Galactic Civil War, up to the end of 4 ABY, during the Battle of Endor. Its purpose was to start a Droid Revolution to exterminate all sentient beings which they perceived as the "inferior biologicals" that plagued the galaxy. However, it was never put into real action, and diminished after its final leader, IG-88A, was destroyed during that battle. The existence of the Droid Army was unknown to the galactic public.
