Thus, what have I learned:
- AI is capable of defending itself and attacking
- USSR Barabarossa AI behaves historical but has enough troops to succeed
- USSR is overpowerd...guess we will see a toned down version in the release
- Germany doesn't get any attack bonusses but their troops are better
- Germany is underpowered 480 vs. 1150 brigades
About the brigade numbers - seems like German number is slightly low (but not so much) while Soviet should be about the same (approx. 500-600) available right off, then another 600 in following month from the mobilization.
Additionally, Soviet units available right off should have low STR and low ORG initially (30-50% STR, 0-20% ORG), to represent their lack of preparation and mobilized units should enter the game with similarly low ORG and STR. Voila, all the sudden everything is right.
I guess testers just focused on 1936 scenario.
