Maskirovka is admittedly a bit underdeveloped atm. It is supposed to buff to your military intelligence and make it harder for the Germans to know what your up to. I planned to add some special decisions to Soviet at one point, in order for the player to carry out their own misinformation campaigns. I will likely implement this at some point.

Oh so its still work in progress. Thats fine. I thought im just being blind due to not seeing the effect anywhere.
