I have the Operation Unthinkable boxed set containing the American and Soviet tanks. The GF9 Operation Unthinkable boxed set, the American versus Soviet, contains 21 tanks. Three of these are the IS-3.
The IS-3 is a Soviet heavy tank developed in late 1944. Its semi-hemispherical cast turret (resembling that of an upturned soup bowl) became the hallmark of post-war Soviet tanks.
This is the GF9 finished model.
This is the sprue.
