   The PT-76 amphibious light tank entered service with Soviet Army in 1951. It was designed as a reconnaissance vehicle. Production continued until the late 1960s and around 7 000 - 12 000 of these tanks were built. Despite it's age this light tank is still in service with at least 25 countries. Russian Naval Infantry currently operates 30 of these tanks.

   The PT-76 has an ideal design for amphibious capability, but both has a number of limitations as a fighting vehicle. It's amphibious design with a boat-like hull and limitations in weight allowed less armor protection. Thin tank's hull is vulnerable to 12.7-mm machine guns and artillery fragments. Later production vehicles were fitted with an automatic fire suppression and NBC protection systems.

   This light tank is armed with a 76.2-mm gun. It has a maximum effective range of fire in 1.5 km and rate of fire of 7 rounds per minute. By modern standards this gun is considered light, but is still capable of penetrating APCs and other light armored vehicles. A total of 40 rounds are carried for the main gun.

   Secondary armament consists of coaxial 7.62-mm machine gun. Some tanks were fitted with a 12.7-mm anti-aircraft machine gun on top of the roof.

   Vehicle has a crew of three, including commander, loader and driver.

   The PT-76 is powered by a V-6B diesel engine, developing 240 horsepower. Vehicle is fully amphibious without additional preparation. It is propelled on water by two waterjets. Auxiliary fuel tanks can be installed for longer operational range.
