[Rules] T-34A/B/C? And T-34/57? And ZIS-30 57mm SPG?

[saracv3]

Here's a most ridic l ous question: An armor guru friend of mine says there is no evidence that a T34c could punch a Tiger I anywhere
In fact, it fell 1mm short at the rear armor. Yet this T34/57 could probably do the job, and other 76.2 variants that the Western Allies had could do the job.

Am I right? And the T34c must have been fodder for the Tiger at Kursk. One wonders how the Soviets won.
