After playing as the Allies for the first time, I see the wisdom of no ftrs for Russia. Sure, you end up spending your tanks in little packets along the Eastern front, but Germany cannot keep up the unit trade if they are also forced into protecting france. By trading spots with a few inf and a tank you are increasing the chances of defensive hits and Germany having to spread their few infantry around further.
One purchase that I am really happy with is a Russian and a Italian bomber. For Russia, I have stationed him in Novo and he can reach the front against germany or fight for Yakut. Plus he can be used in China in conjunction with infantry to make Japans job of pacifying China much harder.
The Italian bmb is even better than a trn build. with this build you can send him to africa to help in attacks and still bring him back to Italy. He can also strike with the ftr in France if there is a small US fleet, not to mention be used in Russia to help can open a square for an attack on Moscow.
