Hi I am new here, so maybee this subject is very old, but I try I am playing Allied and I have SU-122, Su-152 and other powerfull russian tanks, and I am still losing. The tiger and Panther tanks are simply to strong and they can hit me from a long distance and kill my tanks and it's very seldom, that I can kill the german tanks Any idea or way to win over the german tanks ? I will be gratefull if somebody has some solutions Regards Johnny
