Yes, Marbakka, good luck and I hope you are a very patient person. As the Allies, you are generally going to have your head handed to you repeatedly over the first 4 months and you will continue to experience setbacks over the first year or more. It's a very long game, but those first few weeks are singularly tough on you.
But, there are some important decisions you need to make right away. Probably the most important initial decision for you is how you are going to handle Palembang. As you know, this is a vital oil center and will be very much in Japan's early thoughts. If you have read some of the AARs, you know Palembang is also defensible by the Allies. Some Allied players say as a rule DEFEND PALEMBANG; EVACUATE AS MANY TROOPS AS POSSIBLE FROM SINGAPORE . I agree with this, but the smart IJ player will do all in his considerable power to stop this. My goal is to get some artillery there by AP and fly/sail at least two full Bdes, some Base Force aviation support and a HQ into Palembang ASAP....like w/i a week. Use your stringbag torp A/C to hinder (or sink) the naval units he will try to interdict your transports with! Flying is somewhat safer than sailing, but you cannot fly heavy euipment out. Make a maximum effort here.
But, right now, you need to decide whether you are going to make Palembang a fortress and try for the early kill on Japan or whether you are going to strengthen it only to buy time. A "speed bump" defense (which I generally favor). Against the unsuspecting, the "all in" defense (getting everything possible out of Singers, Java, and India into southern Sumatra/Palembang) can win the game within 6 months, but against the experienced IJ player, an all in defense is very risky for you. The IJ may bypass Palembang, contain it and capture Ceylon/Burma/Java and even india if too extensively emptied)
Why Palembang and not Java or Singers? Palembang produces its own supply, is very hard to get to overland due to the very heavy and defensible terrain and is accessable by sea only by smaller vessels. Battleships and very large AP/AKs cannot get up the river. Any attack on a defended Palembang is naturally funneled into narrow approaches. IJ casualities will be high if this Palembang is well"staffed" early. LIKE EARLY!! Get your aerial transports in position and start fying selected units from Singers (many are not restricted...mostly III Indian Corp units. Sail heavy units/artillery from Singers to Palembang if possible.
Enough for now....if you found this helpful, I'll share more Allied strategy points with you later. However, Palembang is a decision you MUST make now.
Okay, one more thing as this decidion must ne negotiated now.. House rules. I never agree to let the IJ have more than the historical shot at PH. They get a free ride/surprise with all its bonuses and the Allies cannot do anything but suffer the first turn surprise. But that is it. The IJ has to return to a 4 or greater port before they can return to strike PH again. That's just fair to me. If the IJ are going to get all those historical surprise benefits, they have to play PH historically and leave after the first strike. They can come back if they wish to pursue a "take Hawaii" strategy (viable), but they have to go "home" first.
