I like more Infantry and keep the offensive with them. R1 - 4INF 2ART 2ARM.
Try R1 - 1BOM 4INF 1ARM?
Here you have a 2ARM 1BOM and a bunch of Infantry to take back a little from
Germany Round 2. The Russian bomber(s) can come in handy later too.
That’s my usual build.
Especially when forced to play low luck, 1 bomber and 2 infantry do wonders to swap territories and you can operate on all fronts from Moscow.
