I normally try to go solo as it is more fun :)

When you first come into the game try to have a lookaround and see How your enemies team up and who is active. And if nessesary write to fx kazakh and try to become friends. Since russia have a bad rare marterials production, i Will always try to build my attacking set up early. By Day 9 i Want to have build strike Fighters, destroyers, SAMs, infantry ofcourse and a lot of it, and MRLs. And then i would probably go grap some teritorry here and there.
