Is there any advantages in refusing the treaty (the one that gives you faster research for armor) as the Soviets? I misclicked by mistake refuse the pact and I am searching for a silver lining since my ironman game is going quite well aside this 
Mutual bonus is not a big problem, honestly. AI anyway won't use armored divisions in really big numbers. You just need to win war in general before it's start by having strong industry, army and air forces.Yeah, I did a bit of research and accepting it gives the Armor research bonus to be used two times to the Germans.I had no idea. It is probably the best thing to do most of the times (refusing it I mean), if planning to fight the Germans, isn't it?
What do you usually do when playing the USSR?
