that should read “try to mix it up”.

after trying it a few times either way I prefer going for Russia (after the initial scare to UK). it’s true the Uk can grow big but you can’t ignore Russia for 3 to 4 rounds they can grow big too, and the UK can remain hobbled by the Luftwaffe and minimal German naval purchases. another reason being that with going Sealion first you still will have a two front war with the US stepping in, whereas with Russian Bear down you can focus towards the single front UK/US.
for a Russian assault I go with mechs and tanks (odd variations) funneling through Leningrad or Stalingrad (I play with the same guys and try not to mix it up). and always with the bombing runs on those two cities, wherever the Russkies don’t have their fighters and Tacs. with the French IPCs I always grab a second Strategic Bomber.
