In comparison to the amount of normal rifle men, the Anti-tank rifle guys are too common in RO. But then again, there is way too many tanks in game too if you think it that way.
I personally like the one tank per side maps, because that is the closest thing we can have to a combined arms fighting. Or actually it is not close to combined arms, it is close to tank fighting as the amount of rifle men vs. tanks is close to a soviet tank brigade.
I can't check german numbers at the moment but they had a lot of men in their tank elements as well.
