What it is:
• Near-simultaneous “pacification” of both Yugoslavia and Greece by the end of October 1940
• Preparation for and execution of seaborne invasion of Greece immediately after fall of France
• Land invasion of Yugoslavia on first possible turn (September 15, 1940)
• Guaranteed 2-turn capture of Yugoslavia if weather in first October turn is fair
• Virtually guaranteed 3-turn capture even if weather turns bad for both October turns
What you need:
1. Early fall of France (by June)
2. Four German tactical bombers on the map
The invasion of Greece is nothing special, so I won’t bother to show screenshots. Just take the whole Italian fleet, 2 German Tacs, 2 German ground units, and whatever supporting units you choose. If you don’t conquer France until July or August, you may have to delay as your Yugoslavia rail moves will take up your rail cap. The nice thing about Greece is that it’s in the Med weather zone, but the sooner you go the better. It won’t mess up your Barbarossa and the chances of RN intervention are much lower.
Or you can just skip Greece altogether if that’s your preference. That decision shouldn’t impact the invasion of Yugoslavia. For that, you will need at least 3 tanks and 2 Tacs ready to roll on September 15, 1940, as shown in the following screenshot.

The 2nd Vienna Award should have been signed at the end of the previous turn, so Hungary (and possibly Romania) are ready to join. Declare war on Yugoslavia. Hungary will join the Axis. Their units won’t be able to move yet, but your Germans certainly will! Use the Tacs and tanks to obliterate the two enemy units north and northwest of Belgrade. See the screenshot below:
Yellow square = starting positions of Yugoslavian units
Green circle = German corps railed in this turn

The Allies will not be able to rail troops to Belgrade, giving you a free shot at the capital next turn. Even if the weather goes bad, you will still be able to mount a strong attack from 4 hexes, 2 on the south side of the river. That Yugoslavian corps will be beat up, and if you play your other cards right the Allies will have to replace it with a weak garrison.
So there you have it. Greece and Yugoslavia in Axis hands before November, and at least 5-6 months to prepare for Barbarossa without having to worry about the Balkans!
One caveat – this strategy leaves no room for Norway; you must either take care of it in 1939, do it later, or not at all. Though I suppose you could do it in fall 1940 instead of Greece. Decisions, decisions…
