Medium tanks of World War II evolved into the main battle tank (MBT) of the Cold War and took over the majority of tank roles on the battlefield. This gradual transition occurred in the 1950s and 1960s due to anti-tank guided missiles, sabot ammunition and high-explosive anti-tank warheads. World War II had shown that the speed of a light tank was no substitute for armour & firepower and medium tanks were vulnerable to newer weapon technology, rendering them obsolete.[citation needed]
