From: Detroit Mi, USA
I have played the 1939 scenario 4 times now as Germany and have split the results. One of the times that I won, I blitzed through them like a hot knife through butter. The other one , I had a very difficult time including keeping a line for 6 turns waiting for them to move. They finally did and I made my move very cautiously I find having bombers are not that important(I had two of them at the start of Barbarossa.( they become important later)
Always make sure you have as many commanders in your panzers as possible.
Just remember, build tanks. tanks and more tanks with a few mechs scattered in and you have to have not only your tech level on tanks at 3, but also upgrade all your tanks accordingly.
I find that I am only able to have two or three panzer armies before the start
You need to take Yugoslavia and then that will be enough time to be ready just in time for Babarossa in June '41.
Another thing I find is that it is better off to take Greece later in the war for it bogs down one or two precious units made for Barbarossa.
I don.t even go after Norway(partly because I am still trying to learn the amphib rules and partly because I control the swedes and let them do the dirty work)I do, however go after Switzerland and can take it in one turn. (the ten victory points come in handy)
As far as Russia goes. when I go deep into the Soviet Union, I run into the blockade in Slovedlsk(or however you spell that). I send as many panzers and mechs as possible over there while I smash into the Caucuses. It took me 8 or 9 months to finally take Slovdlsk. That was December 1943. (luckily the tank sitting there was in clear weather.
I wouldn't build any ships whatsoever, there rarely are any attacks where anything is outright sunk. I wouldn't buy any u boats either for I don't know if they are doing their job as raiding the convoys. (the game doesn't tell you anything about any kind of progress when it comes to that).
The Navy played a big part in the war and this game,unfortunately, doesn't address that.
The bottom line is tanks,tanks,tanks.
