my suggestion would be to start with a general analysis of the russian strategy you plan to play.
that would help me a lot.
OH i meant suggestions for me playing as germany.
Ahh as russia i'm always very aggressive. Too much so. Though i've become a bit more cautious in my old age. Unlike wite w/ 2 day turns you have time to react and prevent major pockets. Things like C&C boning your AP's might screw you up and cause you to get divisions destroyed. But at least with this you can go down fighting if you're cut off and sure to die lash out with an attack at 100% retreat ratio to take some nazi's with you.
I think you'll be surprised by how you can lose a ton of troops but if you nickle and dime the germans after awhile they won't have units at full strength anymore.
The most important "skill" for a russian player is don't give up. You take your lumps but you can bleed the germans dry. And turn 1 start replacing shitty generals. I replace briansk front as the very first thing because him screwing up screws up 3 armies one of them being the 5TA which should be able to put some wood onto the nazi's and help slow the drive on voronezh.
Use your cards (like fortify) i was planning to fortify a hex every couple turns around places i needed to hold onto.
And remember it's not magic instant fortification like WITE you have to dig in still for a few turn's. So don't put the forts right on your front lines thinking they are supermen now. You need to have them be a turn or 2 back since all the fort does is raise the allowed entrench level to 200.
Also if you have things entrenched you can't attack or you lose your entrenchment.
My approach could be all wrong.

But seriously #1 hang in there. There are super dark days in 1941 so be glad we're not playing a 1941 scen. 1942 still has some darkness but you can find places to outright destroy good german units if the german player is not careful. For me the one turn out of 10 where i am able to completely destroy a german unit holds me over for awhile. Unlike atg you can't build rail lines either so you have to remember where they are on the map. There are some parts of the map that are in mountains that you can hold which only serve to keep germans from getting the rail line and hence supply.
