I'm curious how many folks have used Operation Tannenbaum as a substitute for the Low Countries? Although historically only considered after the fall of France, PI has created a nice design where the Western portion of Switzerland is plains, and thus perfectly suited for an armored spearhead! 
In my current game as Germany, I started the war in May. Poland fell by the end of May, and I had all my units re-deployed and ready for a Tannenbaum blitz by the end of June. Here is my OOB:
Switzerland was essentially a byproduct of the endeavor, and by July 2nd the Blitz began:
After the first week, two armored corps began exploiting behind the French lines, while my four infantry corps rushed to keep up.
On July 18th, just 16 days after taking French territory, Paris fell. Unfortunately, the AI decided not to defend Paris. It was odd -- there was a garrison there, which I had Rommel attacking. When I saw he was doing poorly, I stopped the attack, planning to wait on infantry reinforcements... no need, as soon as my attack stopped, the garrison left the capital city! Rommel walked right in.
By August 3rd, just 31 days after the Blitz began, France surrendered.
It sure is fun to use a different method to breach the Maginot! How many others are using the Tannenbaum blitz, and what you your results?
