When the Soviets were defeated, several unidentified animals came out of nowhere for the victorious Allies - Giant Ants. The Allied Commander was given orders from Ben Carville on the pressure of Allied leaders to eliminate the ants, in spite of the latter's reluctance to believe in their existence. It was discovered that the ants came out of a deserted Soviet base somewhere in Europe and the commander was ordered to exterminate them.
