Well, unless you are the worst strategist in the world, if you have amazing dice, odds are significantly in your favor!
What I am talking about is a well orchestrated, statistically investigated and proven Russian open that, even when it fails, you do serious damage to Germany (barring amazing dice by Germany that is!)
In my world, Russia wins if they can kill enemy tanks and not lose any of their own tanks. So even if the attack on Territory 1 fails to take the land, as long as you leave nothing but the fighter there and dont lose any tanks attacking it, you won - you just didn’t win ENOUGH to take the land.
That said, each the odds for each battle are: 85%, 92% and 97% (according to my index card) to WIN which is defined has having at least one ground unit left to take the territory without losing any airpower. Combined that’s 0.850.920.97 or about 76% odds of winning with no loss of aircraft and at most 1 armored unit in all three territories.
Germany loses = 9 Infantry, 2 Artillery, 2 Armor and 2 Fighters
Russia loses (max) = 12 Infantry, 2 Artillery, 1 Armor but gets 8 IPC in territories, 3 of which will most likely not be lost until the middle of the game.
So the equation is this: -12(3)-2(4)-1(5)+9(3)+2(4)+2(5)+2(10)+8 = +24 IPC for round 1. That does not include position on the board, lost opportunities for Germany against the British Navy (and odds are good they are going to lose one of the attacks normally performed round 1) or lost/increased position for the allies. That’s purely financial gain, but even if you look at JUST that, Russia effectively doubles their income with the attack.
There are other triples, some include Belarus or E. Europe or Finland or W. Russia, or whatever. Each have their pros and cons and yes, most of them are statistically against Russia. But some are not. :P
