Thanks for the thoughts!
Mostly I do all those things. I don't always feel I have units to spare for the Bessarabian cities, but I will look into that more. I do use speed bumps, but mostly Mil, Gar, 3 factor Inf, 2-3 factor Cav, and div in cities/forest/swamp.
On the offence, as Germany I don't feel the need to wait for the Stukas. If I can get 3-1 with +2 Blitz I will take the +8 attack. Sure there is the occasional bad roll, but average+ gives good results. Perhaps I've just been lucky, I don't have enough games with enough rolls for the law of average to be too distorted by good results.
I've also read of players that build reasonable amounts of SU air units. I really don't see how they afford that and still have anything like enough ground units. Quick math says that for a July 1941 Barb, the SU gets 6 production phases with 8 BP and 3 with ~14, which is 100 total BP. How much of that do you typically spend on Air Units? I's assume you would build them late to arrive in M/J or J/A 1941? What are you planning the Soviet Army to look like for a 1941 Barb?
Also, and this may well impact results, I also generally follow a France first strategy, leaving only 1 HQ and infantry (along with all the air) to down Poland. My current game I Vichied France in J/F 1940 and was able to launch a 1940 Barb (which I am still playing, J/A just ended). I have never run a "close the Med" strategy with an attack on Spain through to Gib. What I see in the AARs that do this is that too much (IMHO) of the Wehrmacht has to stay behind in Spain and weakens Barb more than I am comfortable with. I do leave a good garrison in Be/Ne/France, I think 12 units with 1 HQ in my current game.
Speaking of AARs, I read a lot of them here, but I can't remember too many where SU does well. Can someone recommend an AAR that had good SU play?
