The Vietnamese army is upgrading some of its original 300 Soviet-made PT-76 tanks. Among the tests conducted with the upgraded vehicle, water obstacle crossing took an important part, something obvious for amphibious tanks to be used in a country with such important waterways and shores.
The PT-76 is a Soviet-era amphibious light tank that was introduced in the early 1950s and soon became the standard reconnaissance tank of the Soviet Army and the other Warsaw Pact armed forces. It was widely exported to other friendly states, like India, Iraq, Syria, North Korea and North Vietnam.
