The T-72 is a Soviet-designed main battle tank that entered production in 1970. It is a further development of the T-62 with some features of the T-64A (to which it was a parallel design) and has been further developed as the T-90. Chronologically, and in design terms, it belongs to the same generation of tanks as the US M60 series, German Leopard 1, and British Chieftain tank.
