The Tank, Heavy, TOG 1 was a prototype British super-heavy tank produced in the early part of the Second World War in the expectation that battlefields might end up like those of the First World War. It was designed so it could cross churned-up countryside and trenches. A single prototype was built, and followed by an improved model (the TOG 2), but interest faded with the successful performance of another cross-country design, the Churchill tank, and the mobile war that was being fought.
