What could have been an incremental improvement on the legendary T-55 instead became a revolutionary tank as a string of weird co-incidences and sliding doors moments lead to a the end of cannon rifling and the invalidation of steel armour.

Todays western tanks with their composite armours and smooth bore cannons are the response to the Soviets development of the T-62, a tank we're going to get to know a whole lot better in this episode!
