T-64

Although the T-64 looked similar to its predecessors (the T-54, the T-55, and the T-62), it represented a leap forward in Soviet tank technology at the time. It featured a 115mm gun, a new suspension that included six small dual road wheels, and improved armor that incorporated ceramic inserts. Despite these improvements, the T-64 was expensive to build, and reports of its reliability were unfavorable. It was relegated to a lower status in favor of the more affordable (and eventually much more widely produced) T-72.
