Point taken TG Moses on the not wanting to split up the Russian army. Admittedly it is better served being one and able to punch into German territory at will.
The reason I split things is because I view the game in terms of pure economics… IF you can simply keep Axis on the defensive, eventually you win out as Allies. So for my play as Ally it’s not as important to mount an offensive as Russia against Germany but simply to get enough troops surrounding Germany so that she can no longer expand. Basically it gets to the point where all she controls is Germany, WEu, SEu and Eeu and maybe Ukr (if trading off as a dead zone).
Controlling Germany is easier than Japan because you have more forces and more local ability to get defensive positions (via UK troops to Karelia and US troops as well) and to threan WEu if the Germans aren’t honest there. But with Japan, US forces are far, far away and likely you have no navy (everything to Europe), plus even if you did there’s nothing in the pacific that will really put a dent in the Japanese economy except maybe Phillipines. And UK unless you have IC on India in T1 you don’t have local forces and anyways you should concentrate most of you efforts against Germany (tho that part is up to personal discretion and gamestyle).
Which leaves Russia as the only force who can get large swaths of infantry to confront the Japanese within a few turns and can keep pumping out 8-9 INF a turn against the Japanese (getting a tank every now and then to launch the limited offensive).
Once Axis can no longer expand, barring some really fluke die rolls, it’s a matter of time before Allies win. So that’s why I try and have the bulk of the Russian army on the East against Japan after the first few turns.
It’s my style of play but I can certainly see where you have a point about the Russian army being as one and fighting Germany.
I have a question: how do you confront the Japanese if you do that?
