The TOG2 (Tank, Heavy, TOG II*) is a British World War II prototype super-heavy tank. It is notable for it's long hull length (10 meters) and overall size. The TOG2 was designed early in the war to overcome First World War style trench warfare, though it's intended operating conditions never materialized and it was quickly obsolete. It was designed by the Special Vehicle Development Committee (nicknamed "The Old Gang"), which consisted of people who had worked on the Mark I Tank.
The TOG2 became somewhat famous after it's inclusion as a premium tank in World of Tanks, where it was easily recognizable for its size and bulky shape. It was generally known for being large and slow, but with a good gun and very high hit point pool.
The single prototype of the TOG2 can be seen at the Tank Museum in Bovington, England.
