Microing stg44 panzer grens does it for me, what I mean is not stay mobile just never stop it is the best way to avoid any kind of arty. One example, I had 4 STGs and 2 schrecks in 2 equal control groups send one around each side while keeping dispersal with a mortar to keep any MGs off your back, . You need to be decisive and aggressive even to the point where your opponent thinks you will waltz into a trap baited by said mortar and then you know another point in the line is under powered. Kill them enough and they will notice the massive manpower drain. I often only get them only in the beginning to essentially cause brick shitting and break newb city defenses.
