This is an injection-plastic military vehicle model kit.
From the Trumpeter website:
The T-64 was conceived in Kharkov as the next-generation main battle tank by Alexander A. Morozov, the designer of the T-54. A revolutionary feature of the T-64 is the incorporation of an automatic loader for its 125-mm gun, allowing a crewmember's position to be omitted, and helping to keep the size and weight of the tank down, and the T-64B of 1976 would be able to fire a guided antitank missile through its gun barrel.
The T-64 would be used only by the Soviet Army and never exported, unlike the T-54/55. It was superior to these tanks in most qualitative terms, until the introduction of the T-72B model in 1985. The tank equipped elite and regular formations in Eastern Europe and elsewhere, the T-64A model being first deployed with East Germany's Group of Soviet Forces in Germany (GSFG) in 1976, and some time later in Hungary's Southern Group of Forces (SFG). By 1981 the improved T-64B began to be deployed in East Germany and later in Hungary.
When completed, this model measures about 261mm long, and 105mm wide. Parts come molded in gray. Includes photo-etched parts and decals.
