The TOG II is a prototype super-heavy tank designed in 1940 by the Special Vehicle Development Committee a.k.a "The Old Gang", which consisted of the original designers of British tanks during World War I. The tank is a follow-up design of the TOG I, which was designed with the expectation that the next world war would devolve into static trench warfare much like the first. To achieve this, the TOG II has a very long and relatively narrow hull to help it traverse trenches effectively, and at one point even planned to be equipped with sponson turrets to ward off infantry attacks from the sides. As speed was not a priority, the TOG II's top speed was expected to be around 25 km/h, though in reality it could only achieve 13.7 km/h due to its sheer weight.

Unfortunately for the TOG II, as World War II developed into an Europe-wide conflict, it became increasingly clear that trench warfare was not how warfare would be waged during the conflict. With the advent of mobile warfare, the sheer size and lack of speed of the TOG II meant that it was hopelessly obsolete from its inception. In an attempt to keep the project relevant, "The Old Gang" tried mounted various modern and experimental armaments onto the TOG II, with the most notable attempt being the use of the prototype turret of the Challenger tank with a 28-pounder gun. However, this proved fruitless, as the TOG II was fundamentally not designed for mobile warfare, and the project was cancelled in 1943. The sole prototype of the TOG II is currently preserved at the Bovington Tank Museum.

Introduced during Update "Kings of Battle" as the reward for the "Dreams Come True" 11th Anniversary event, the TOG II is a gargantuan "super-heavy" tank designed for a static trench warfare scenario that never came to be. As such, the tank's distinctively long hull sticks out like a sore thumb among the ranks of its contemporaries. Unfortunately for the TOG II, the tank is only really called a "super-heavy" due to its sheer weight of 81 tons (with add-on armour), while its overall armour is mediocre at best. Being designed to climb over trenches and that alone, the tank ends up being quite slow and won't be outrunning anything. Fortunately, the TOG II has a large 28-pounder (94 mm) gun as its ace up its sleeve to make up for its other shortcomings. The gun has high penetration and with the high turret traverse speed the TOG II can effectively threaten tanks well above its BR. The TOG II thus excels at fire support from behind friendly tanks, or slowly advancing towards the enemies with your teammates to cover your weak flanks.
