The Tog II was a development of the Tog I, a British tank. The diesel V12-powered tank was conceived with the idea that tough terrain and tough conditions similar to World War I would necessitate a heavier duty machine, but it never made it out of the prototype stage when World War II changed in such a way that it was deemed unneeded. ¹⁾

The German-built Jagdtiger (translation: Hunting Tiger) was a beast, measuring about eleven meters in length and weighing 83 tons when fully loaded with ammunition and crew. The tank's design concept was that bigger had to be better, however due to poor reliability, the few that were produced were abandoned on the battlefield.²⁾

The T30 was an American-made heavy tank that saw limited action due to its development coming to a close as WWII came to a close. The T30 weighed 145,000 pounds and was outfitted with a powerful 155 mm main cannon, as well as two machine guns for backup. The T30, which was essentially a stillborn concept, would have been a brute in wartime exercises. ³⁾

The T28 Super Tank is the largest tank ever constructed for the United States Military and is yet another example of a big tank being finished in prototype form but never making it to the battlefield. It was eleven meters long and weighed 95 tons loaded, believing that such a machine was required to fight Hitler's army. ⁴⁾
