I have created a detailed format that I like to use as Germany, and it is primarily a G4 Barbarossa invasion based strategy.
G1: Purchase: 1 Aircraft carrier, 1 Destroyer, 1 sub
France: 7 inf, 3 art, 2 mech, 4 armor, 1 tac
S. France: 2 mech, 2 arm
Yugo: All German land units in range, plus 1 fight from Romania
SZ 110: 2 fights, 2 tacs, 2 strats, 2 subs
SZ 111: 2 fights, 2 tacs, 2 subs
SZ 106: 1 sub
Annex Norway: 1 inf, 1 art via transport
ANnex Bulgaria: 1 inf
This first turn layout is my optimal choice for Euro axis strategy. By taking Southern France, you acquire a factory in the med, which offsets the Italians not taking S. France or Yugo. The two seazone attacks are 100% victory if UK does not scramble, and 80% plus if UK scrambles everything in both. At the end of your turn, you move a sizable force to the Eastern Front, whilst having 1 battle ship, 1 aircraft carrier (fully loaded), 1 cruiser, 1 destroyer, and 1 sub to protect your coast. This is also a perfect feign for sealion.
The Italian turn varies too much on UKs moves, but in general, I will attack Greece using my transports that survived, which allows them to remain under Italian air cover.
G2: Purchases: 5 inf, 5 art, 1 strat, 1 minor IC in Romania, 2 subs
Normandy/Bordeaux: Whatever Germans are left in France
Reinforce Finland: 1 inf, 1 art via transport
Move from Yugo to Romania
Collect: 54 IPCs
Granted, G2 all depends on what UK did. If they did not defend England properly, i will buy 6-7 transports and take it next turn. I like the 1:1 inf:art ratio here because I am transporting artillery from Poland to Finland, leaving me with little artillery in Poland. Again, this whole turn is variable, but generally, UK will shore up defenses in England and I will follow the moves listed above. If I don’t want to wait for G4 attack, I won’t build the factory.
As for Japan, a J2 or J3 attack is prime, preferably the latter, as my Germany strategies assumes a G4 attack on Russia.
Everything after this is to variable, other than a constant supply line of 6 infantry and 4 artillery being sent to Russia (plus 2 inf, 1 art in Romania).
