a good Russian strategy depends on what the Allies are doing overall. everything i post is assuming Dice because dice allows the probablity factor unlike Low Luck.
Also it is important that the Brittsh will kill the Itlian fleet R2 or R3
KGF
Buy 4 tanks 1 fighter you have enough inf for turn one not to buy any.
A basic strategy I like is to give up Karelia leaving one man behind and regroup in Arch(with AA gun from Kar) then R2 counter
As well as take back the Ukriane R1.
my buy round two varies but if i can one figther that being the last one i will buy for Russia heres how i would get the money if going for a fighter buy R2, on R1 i attack Finland with Kar if doable and take ukraine. leaving baltic states and East Poland to the Germans + getting your bouns for no allies in your country which is a given R1, giving Russia 35 Ipcs on hand. then buy my 4inf 2 art 1 tank 1 fighter giving me two fighters to swap territories with. Fighters act as permanent tanks and don’t die when the territory you just took is recaptured, From R3 out i buy twice as many inf as i do art or tanks and i try not to buy more than two tanks that way i get the most units down so i can hold my capital and still have enough boots to swap with, when The Japs arrive on scene i pick my battles wisely. now at this point the Brittish and the US should be set and start destroying Germany by round 4 which means less pressure against Russia,R5 should be the last German push then you focus mostly on the Japs. russia’s goal now is to swap persia and kill the intial Jap force that will be coming north which won’t be there in force until Round 6. All they have to do by R7 is survive swap novo, persia, Kazak, and Evenki there shouldn’t be any German/ Italian Offense at this point and if there is your done for.
KJF
I do the bury stack and along with a India IC (KJF) is going to be built by the Britts I would go with 4tanks and a fighter(or 2inf 1 art) 3 tanks in Caucus R1 then R2 back the inda IC with those three tanks, so India has 4 britt inf 1 britt art and AA gun and 3 rus tanks. versus 4 jap planes and 4 inf Defender wins 73% with 2.78 units left (three tanks). If at all possible I bring those three tanks back R3 by then jap should be buying navy to fight the U.S. A KJF means to me three tanks a turn by the britts in India and the Britts killing the Itlian fleet, along with the Britts fighting for Karelia via SZ 4. I then try to back chinghai with one inf a turn from russia.
My Russia KJF then starts to look more like my KGF but now there is no Japs and all you have to do is just swap one teritory away.
In all Russian Strategies it is Key that all of your offensive battles take place at least three teritories away from Germany that way you don’t get your guys killed by a spawning tank/German airforce combo.
Also, Reading this I see alittle bit about a navy and I know for a fact that no surface ships that Russia builds will stand to a german airforce. and subs seem like a waste to me.
I have yet to try to the bomber strat because I like the fighter defence over the bombers because russian offense isn’t always an option especially if the Italians try a one two punch with the germans and stop the Russian one man blitz blockades.
