Hi, as Germany in Single Player mode I was annexing the SU after long fights. Well, I was a bit disappointed that the economic power of these province added almost nothing to my IC count. But worst is that the US were able to annex Japan and were sitting at the eastern border and took the chance to invade from the east. God, is the SU a wide land! Before I was able to get my troops to the eastern end of the SU the US did a wide invasion into the country. And when my troops where finally there they where not able to fight them back because the supplies were too short. The US and Nat. China forces on their end had no supply problems.
What can I do to improve the supplies for the east SU?
And why is the Berlin HQ theatre pinned to Berlin when under AI and other, own created theatre HQs move with their troops ? Why is the AI moving exhausted divisions about three provinces away from the front to let them rest and opens holes in the front lines doing so? Wouldn't it make more sense to let them dig in that case?
