Comparing: M10 Wolverine vs. AT 2 vs. SU-85

The most widely produced American tank destroyer, with a total of 6,406 vehicles manufactured from September 1942 through January 1943. More than a third of all Wolverines were supplied to Allied nations under Lend-Lease.

Design for an assault tank to break through enemy defensive lines. The design was completed by May 15th, 1943. No prototypes were built, the project helped set the stage for another heavy assault tank, the A39 Tortoise.

Developed on the basis of the T-34 medium tank and the SU-122 assault gun. Produced from August 1943 through July 1944. The 85-mm D-5S gun allowed the SU-85 to effectively hit enemy medium tanks at distances of more than 1,000 meters and to penetrate the front armor of heavy tanks at shorter distances.
