A destroyed Chinese Type 62 with a Vietnamese soldier, Sino-Vietnamese war of 1979. The Type 62 Light Tank was basically a smaller and lighter Type 59. Armed with an 85mm gun, it wasn’t really a match for even old MBTs or LTs, but it could go where MBTs could not, which was especially valuable in the difficult terrain of southern China and northern Vietnam. The vehicle was used during the Vietnam War and the Sino-Vietnamese War and was also exported to Africa, but it wasn’t particularly successful. It was quite vulnerable to pretty much anything bigger than small arms, especially most RPG type weapons.
It was useful when the enemy had only rifles or machineguns but anything heavier would deal with it rather quickly.
