From: Hex X37, Y15
There's a totally vulnerable motorized division in a clear hex sitting next to massive and fresh units just west of Moscow, for example --it can be hit on 4 sides, for christ's sake. I would be all over that like white on rice.
He would lost around 1-2 Cv I would 3-4 times more. Not great considering the fact that he is strong near Moscow, barely do anything at all and I will assault his positions along the front next turn.
Large sections of his line are being held by regiments. He needs to be punished for that. He's doing whatever he wants to do secure in the knowledge that he can get away with it. 3 rifle divisions can kick back an undug regiment in clear terrain, easy. If you've let them get dug in...that's your fault.
I do not have enough strength to attack his regiments properly, plus he has not committed his panzers so I can easily be punished for being aggressive without having any depth.
While you will lose more than the Germans even on a successful attack, you can replace the losses, he cannot. And it will drive down his morale and give you wins that you need for guards conversion.
I agree with Flaviusx, you seem to be too passive. He has achieved psychological domination. If you let the German hold large stretches of the front with regiments and don't to anything, you leave him free to concentrate wherever he wants. You must force him to spread out, which will inevitably make his attacking thrusts weaker. Being passive just plays into his hand!
You only really need slightly more CV than he has to attack, the 1:1 will kick in and do the rest!
Nice job in the Crimea though!
