And the Ostheer totally destroy the US once they have a tiger. Weak early game, strong late game. I think some units could stand to be tweaked, but I don't think the balance particularly favors either side.
Unlike the Soviets, the Americans can get both a main battle tank and a tank destroyer from the same tech structure. You can easily pump out a Sherman after your strong early game, and have enough resources for tank destroyers to deal with the tiger.
Only the Tiger ace can be a big thing for USA to deal with, because of the +10 range, sight, instant blitz and TWP. Jacksons have no issues dealing with a standard tiger.
