Development of the PT-76 began in the late 1940s, and it was introduced into service in 1951. It emphasized mobility over heavy armor and firepower and was designed as an amphibious light tank. Its primary roles include reconnaissance, infantry support, and river-crossing operations.

The PT-76 features a fully amphibious capability, allowing it to cross water obstacles without preparation. It is equipped with a 76.2 mm D-56T rifled gun, capable of engaging light armor and soft targets. The main armament is supplemented by a coaxial 7.62 mm SGMT machine gun. The vehicle's thin armor provides protection against small arms fire and shell fragments but is not designed to withstand hits from larger caliber weapons..

The PT-76's V-6B diesel engine provides a modest 240 horsepower, enabling a top road speed of 44 km/h and a water speed of 10.2 km/h. The vehicle's lightweight design and amphibious capabilities made it an ideal choice for reconnaissance and support roles in riverine and coastal operations.

The PT-76 saw widespread use in the Soviet Union and was exported to numerous allied countries. It participated in various conflicts around the world, where its amphibious nature and ease of maintenance were highly valued. Although it has been largely retired from frontline service, the PT-76 remains in use in some countries for specialized roles and training purposes.
