Over 4000 examples of the diesel-fueled M4A2 Sherman were sent to the Soviet Union during WW2 under Lead-Lease. They were operated by Red Army crews during some of the bitterest fighting on the Eastern Front. Well-liked by their crews but relatively little has been written about them until now.
A good, short, but relatively comprehensive guide the Shermans in Soviet Serice. It reveals details I'd been totally unaware of. Worth the price.
