Command & Conquer Generals Black Sheep Mission

Black Sheep was originally slated to be the third mission in the Global Liberation Army campaign where players were given command of the Toxin Tractor, a slow-going farm vehicle modified to spray a deadly corrosive agent, and ordered to eliminate the town that had been corrupted beyond salvation by the USA's propaganda. While the mission was ultimately removed from Generals, the Toxin Tractor was available in other campaign missions, as well as in multiplayer and skirmish modes.
