Doh! Thanks, that the part I was missing. Now alles klar.
I'm pleased to be of help because I was reading your comments with great interest. My gaming diet pretty much begins and ends with WiF, and it was interesting to see how it looked to an experienced gamer when they dived straight in. I'm sure you will master invasions soon enough, but you are coming into contact with a legitimate flaw of the game in that it just doesn't seem logistically possible for Japan to match what it did historically. Or if it is, it requires game play of the very highest standard, which few will ever reach. With that said, I love the game to death, and hope you persevere with it. The rules may appear peculiar at first, but their logic will become apparent soon enough.
that's interesting to me because once you know all the fine points of operating World in Flames armed forces, the Japanese can really build a big Co-Prosperity Sphere if the Germans are doing well in Russia and the Allied focus has to be on that. The Japanese can overrun most or all of China and have an Empire from Capetown to the Persian Gulf to Pearl Harbor in the game if the Allies have trouble in Europe. In the real war this would have been simply impossible due to Japanese brutality, not enough Japanese men to occupy such a vast portion of the globe, and perhaps the ways Bushido wasn't well suited to managing 20th century military logistics (something I want to study more, but can't in this game). WiF makes logistics super easy compared to history, and Partisans are too weak in the game. Japan could barely maintain it's grip on the pieces of China it did occupy because it struggled to feed it's own occupying troops everywhere; they operated on more of a logistic shoe-string than the Germans. The Japanese had to launch regular Rice Offensives inside the previously conquered territory to seize agricultural yields; this kept them from advancing deeper into China more than the Chinese did, I think.
But if the Germans are hung up on the Dnepr, Russia isn't in much danger and the Allies can simply throw hordes of Infantry in the path of the Japanese, with little concern for replacing them since they are just cardboard or now pixels. Only the Chinese had that option in the real war, but even they were more concerned with the next war than the war with Japan and they too can too easily fight the simplistically supplied WiF Japanese.
