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⁾

The Panzer VIII Maus was another German tank that was not only enormous and nasty, but also extremely heavy. Though the beast weighed nearly 200 metric tons, it was also too heavy to reach anything resembling cruising speed and would struggle to traverse most bridges. Before Germany was overtaken, just two prototypes were built. ⁵⁾

The Landkreuzer P. 1500 Monster only existed on paper, but if it had been built, it would have been a scary asset of devastating proportions. The Monster, designed by German forces to carry an 800 mm rail gun, would have been exactly that, considering the weapons could devastate practically any opponent hold. ⁶⁾

The British-built Challenger 2, often known as “Megatron,” is a generally successful brute recognized for being well defended against enemy fire thanks to a strong Chobham armor system. The Challenger 2 has served in the Balkans and in Operation Iraqi Freedom, though it is not a speed machine, with a top speed of 37 mph. ⁷⁾

After the old M4 Sherman was outgunned in WWII, the United States Military developed the M26 Pershing, albeit too late to have a substantial impact on the war effort. This 46-ton machine, on the other hand, served in combat missions during the Korean War and had an amazing track record when it came to demolishing enemy tanks. ⁸⁾
