Leave the forts out, leave the anti air guns out.
For your divisions: you need to build up to at least 30 armoured divisions, like ARM MOT TD AC works good enough I think against the AI.
For you line infantry, leave the AA out at all. Focus on inf inf art at or inf inf inf at. Officer ratio needs to be ~100%, should be achievable.
No strategic bomber and only build CAS if you build more INT/MR/CAS, otherwise leave them out too.
So you are saying that I fail in my pre-war build up? The end game for Soviets?:sad: Mostly in 1936 - 1939 years i was building IC and army for Far eastern theatre, and after German invasion of Poland I began to concentrate on building army against German. A little too late:angry:
