Tanks were invented back in WWI (Took a lesson from the cars, AKA "Horseless Carriage".) "For nearly 5000 years, man has sought a way to devistate his enemys while protecting himself. The early war wagons, the chariot, the knight. Though men like DaVinci dreamed of armored vehicles, it would take the advent of the industrial era to bring them to reality.
