And to counter MGs you rush them with random infantry units?
No and I never implied that I do that.
Countering combined arms requires combined arms and some thought to it, for example attacking from the side that isn't dug in to annihilate your advance.
Where is your arty to dispose of ZiSes and infantry? Where is your reckon plane to know how you can approach it? Where is your flank?
Yes youre right. Of course im not talking about head-on charges, but well executed flanks. Then again: You can bet support will be there (IF your enemy doesent loose all his support units because of an arty barrage, but then the game is essentially over anyway) and your flanking tanks wont die to the ISU but to the support then...which is why you need to bring your own support, which will die to ISU, which is the problem were talking about here
