It's currently april 1940 in my current Germany game, and Poland and France have fallen. I started my offensive in the west in June 1939 and it ended late October. I went through Belgium and Luxemburg, ingnoring the Netherlands. While it wasn't necessarily hard, I feel like France could've fallen quite a bit sooner. I performed the invasion as Poland more like an operation, keeping some infantry on the entire border and sending armour to key provinces. This was extremely succesfull and I think I conquered them within a month with very few battles. That's what my initial plan was for France too: sending armour through the plains in western Belgium, quickly taking Paris and surrounding VP's. Before I knew it however, I was bogged down by relatively lots of French and Belgian troops (as the front was quite small). Having to cross lots of rivers wasn't helping either. By the time I conquered Belgium, the French already had troops on their entire border (also drawn from the Italian border) and I just put down a full corps at every border province too. At that point I started major offensives along the entire border, steadily moving deeper into France. I had more and superior forces, so it wasn't hard, but it's not exactly what I'd call an 'operation'.
So my question is, what are some good things to do when you're planning on taking out France ASAP? The obvious one is researching Operational level organization ahead of time and I think officers reduce attack delay too, is that right?
Now something else that's bothering me is Barbarossa, mostly the scale of it all. Having to control all these divisions along a massive border is kinda scaring me off. The fact that the border is growing larger the more I advance is making it even harder. This isn't really a question as I'm pretty bad at wording all this, but the main thing is: Barbarossa is overwhelming, some general tips or advice that could help me with that in particular? I'm the kind of person who likes to keep his OOBs perfectly organized, having the same type and amount of divisions spread out evenly, which is probably a reason why I'm having a problem right now.
Oh I do have one actual question regarding Barbarossa, would one INF division that packs a punch (3inf/2art or something like 2inf/2art/1at) be enough to hold the line while I advance deeper into Russia with armour?
Now this is quite some text, but I'd be more than happy if someone could provide me with some short general answers and advice, which is the main reasons I didn't create 2 seperate threads.
