R1 I purchase 1 bomber and 4 infantry.
Yeah me too: sometimes a bomber, sometimes a fighter.
Some air force is perfect, no need to sacrifice tanks and you got strength + distance (and great defence later in the game in case of fighters), and turn 1 is ideal for this since after R1 there shouldn’t be any threat.
Only reason i would buy a few tanks with Russia is to have units that can drive into India and China fast. If USA buys an IC in China they need Russian support.
Edit: and now and then an ART of course
