So Razor’s math is invalid.
WWI tanks were about reaching and overcoming obstacles such as barbed wire and trenches, preparing the way for infantry. They did have armament, but of rather limited effect compared to WWII vehicles. Essentially, they were designed to lead infantry assaults.
WWII tanks (at least after 1941) were principally mobile artillery platforms, and as such were as powerful in defence as attack.
I agree with the way tanks are depicted in the new game; I just feel that they may be a little overpriced, or under-powered in attack. By slowing down the combat, they defeat the object of a breakthrough weapon…
But I’ll need to see them in action to be sure.
