With Red Thunder close to making its way off the production lines, I was wondering how capable Russian AFVs are at dealing with German Armor. At first sight, many of the guns utilized on Russian AFVs have much larger calibers than the Allied guns commonly seen in CMBN.
The typical Allied AFVs sport 75mm, 76mm, and 105mm calibers, whereas the stock Russian guns of T-34s, IS tanks, and ISUs are much larger at 76mm, 85mm, 122mm and even 152mm. At first glance, one would draw the conclusion that Russians tanks were much better equipped to reliably penetrate German armor compared their western counterparts. However, I don't believe that the caliber of the gun is the best indicator of armor piercing capability. For instance, I've read on Wikipedia or somewhere that the Russian 122mm gun could not reliably penetrate the frontal armor of a panther, but I've read posts in the forum that suggest otherwise.
Does anyone know how effective Russian AFV guns were at penetrating frontal armor of German tanks?
