The M60A3 main battle tank was designed in 1956 and entered service in 1960. The M60 was a big, tall tank with a rounded turret and heavy armor for its time. The A1 and A2 versions both fought in Vietnam. The A3 version had improved night sights, a laser rather than stereoscopic rangefinder, a ballistic computer, full stabilization, reactive armor boxes plating the turret front and side, and defensive smoke systems. It weighed 52 tons, had a crew of 4, used a 750 HP diesel engine, had a maximum road speed of 48 kph, carried a 105MM main gun and 63 rounds of ammunition, and production ended in 1987. This tank was acquired by the town of Edgefield through the help of Headquarters, 122D Engineer Battalion (Combat) and the South Carolina Army National Guard on 5 March 1996.
