a first round attack at karelia with at most 4 fighter’s, 1 bomber, 1 infantry and 1 artillery, against 5 infantry, and 1 artillery, would hit at best 4 at the first round,
if all aircraft survive the anti-aircraft gun, with the defender hitting 1-2 at least, that mean’s that the land unit’s, or 2 aircraft would have to go,
if you lose the ground unit’s you can not take control of the territory, a second round could bring more losses, with no way of reinforcing karelia until g2, are 2 i.p.c. worth all that airforce, with russia left with 4 infantry and 1 armor, they could easily take out 1-2 ground unit’s, at the next round
after russia 1, the axis could face 7 infantry, 2 armor, 1 fighter at the caucasus, with reinforcement and non combat movement, for the 41’ scenario there is no nescessity for russia to reinforce at russia, russia can send all it’s unit’s to the front, to slow down the german attack, and build at russia at round 2, if the caucasus has not been captured by round 2,
that would mean that the axis had lost a lot of unit’s there, and if that happen’s you have to rebuild from germany again,
if you give the russia player 1 easy round without taking territories or by losing unit’s for a hopeless battle, and set germany back 1-2 round’s, that is all the initiative that the russia player need’s to counter strike, if russia get a foot hold at a gray territory, it is as good as game over for germany,
if you give the initiative to the russia player they can easily send 1-2 infantry, 1-2 armor east to stop a japan attack,
if russia take poland and romania/bulgaria that almost gives russia twice as much i.p.c. as germany, russia can then pick off the german unit’s that are sent east, and with less i.p.c. to spend, france and scandanavia would fall within 2-3- turn’s
i think that an all out attack at the eastern front is a bridge too far, and far too risky,
the german player need’s to constantly attack at the red territories, or at least stop a russia advance,
if the strategy work’s for you, post it here
