OTL the MAN Panther prototype was chosen solely because it was believed to be quicker to get into production, which as we all know did not end up happening. What if the DB design had been chosen? I can't really see any disadvantages to it. It combines the best features of the T-34-sloped armor, cheapness, reliability and ease of production, with the best features of German tanks-three-man turret, the 75 mm gun, great optics, and radio. I understand that there could be a friendly-fire issue, but wouldn't there also be a corresponding one for the Soviets?
