The TOG2, officially known as the Heavy Tank, TOG II, was a British super-heavy tank design produced during the early stages of World War II for a scenario where the battlefields of northern France devolved into a morass of mud, trenches, and craters as had happened during World War I. When this did not happen, the tank was deemed unnecessary, and the project terminated. A development of the TOG I design, only a single prototype was built before its termination.^[5]
