The T-64 is a Soviet second-generation main battle tank introduced in the early 1960s. It was a more advanced counterpart to the T-62: the T-64 served tank divisions, while the T-62 supported infantry in motorized rifle divisions. Although the T-62 and the famous T-72 would see much wider use and generally more development, it was the T-64 that formed the basis of more modern Soviet tank designs, such as the T-80.
