Do you know Tanks?

Hunter1911: The Yugoslavians also got their hands onto the Sherman. The M-634 was a project using the V-2 engine from the T-34 in the Sherman, the new engine have the Sherman some extra horsepower and speed.    Later the M-634 evolved into the SO-122 which changed the gun from a 75 mm gun to the Soviet A-19 122 mm gun.  The comfortability of the SO-122 is minimal, IIRC it has a whopping -2 degrees of depression.   After WWII Yugoslavia found itself possessing a lot of both US and Soviet steel. They tried combining best of both worlds, as well as producing their own vehicles.   M-634 was a result of one such attempt of infusing a T-34 engine, the V-2 into a Sherman tank. Project resulted in Sherman with some more kick, but also having severe issues with cooling down the engine.   Code-name for the project was "Violina" or Violin in English (You dont say).   There were quite a few hybrids between US and Soviet tanks crafted by Yugoslavians.   Personally my favourite is Vozilo B (vehicle b) a T-34 variant with 90mm M3 gun   Now...Who can name this little guy :)
