Main battle tanks designed by the Soviet Union have been in the news recently thanks to certain events on the global stage. Vehicles like the T-72 and T-80 show their age, but some don't realize how old these designs are. The T-64 from which these designs are derived started development not long after WWII. Out of the three designs, it's probably the most maligned, but just how bad was it?
