The first workers that built them were told they were making water carriers for Mesopotamia. It made sense since the company that made the first working model in 1915, William Foster & Co., worked in agriculture. That 18-ton model housed a crew of six and was nicknamed “Little Willie.” It was never used in combat. From that humble, secretive beginning, tanks have become one of the emblems of military might.
But which types of tanks have done the most damage? Which models of these war machines left enemy armies the most devastated? Not just “which tank has the most destructive potential,” because that would only be a list of the most modern tanks. No, we'll be focusing on the tanks which were put to the ultimate test on the battlefield.
