If you’re gonna setup for anything, setup to give yourself thr maximum amount of options.
Group the bulk of your armor in EPL,
from here you are always in the possible position of blitzing KAR, CAU, and RUS. Not to mention if you can keep enough units coming, always able to keep your 2nd NO.
This puts the russians in very awkward positions, he cant lose his little battles, or he’s exposed, and he has to defend all of his factories at the same time, with a stack equal to your stack.
This also means then that more of his infantry are forced to attack, and then exposed to overwelhming counter attack (if you can spare a fgt or bmb or 2) in which you usually come out a few IPCS ahead.
Couple this with Italian support, and you can punch holes for your German armor all day long.
even if dice turn bad for you, and you never get an open break for a factory in the east. you’ve managed to keep the war that much farther away from Berlin, for that much longer.
