Well now i know what my next game will be.

Outnumbering is only important to a point. if your divisions cannot reinforce a battle that is limited by max width of 80 in time then ALL divisions will be defeated and retreat.

This is why reinforce rate is so critical a technology.

Well, the answer was doing 30w, 8 inf, 3 art, 1 AT, 3 mot, 1 LT TK.

Also spawning like 80 proletariat divisions, Germans will push you insanely hard but you will get decisions that help. Also this mod is kind of stupid cause its "hsitorical" aka giving you ♥♥♥♥ debuffs instead of letting you fight

Well i halted German. At historical lines too. My primary strat was Garrison troops. Nearly as strong as regular inf div on defense by 1/2 the price so could spam immense numbers.
Built up a strong heavy tank force and counter attacked and won.
