These are NOT optimal strategies. They are meant to be funny and either ridicule “standard strategies” or make fun of losing situations. Let me explain tthem to the best of my abillity:
Germany:
Must kill Russia and not worry about anything else like Sea Lion or Africa. This comes from many players who believe that taking Moscow early is the only way to victory for Germany.
Soviet Union:
This comes from the classic Russian build up early on which is soon negated by overwhelming German force. It ridicules those who just stack Moscow instead of trying to counterattack.
Japan:
1 symbolizes the J1 attack which is used more than J2 and J3
2 symbolizes taking the money islands
3 symbolizes getting so rapped up is Asia, that you allow the U.S. to take Tokyo (lol!)
U.S.
This is actually quite true: with the U.S. you must get enough force to defend yourself or make a hole in your opponent. Then you must get into a great position like Gibraltar or Carolines. Then eventually you get that great opportunity–wham!
China:
This, of course, is about players who think China is useless. In my personal experience, I think most people just like to sacrifice Chinese units. And of course such gameplay will cause Japan to hit Stalingrad and then Russia yells at you.
United Kingdom:
Europe:
Defending is important early but only in the UK itself. If Germany at least threatens Sea lion, we see UK just defending for awhile. Then finallly they make a big blow like Rome or Denmark.
Pacific:
This ridicules players who just build infantry and simply put everything in India. You bet they get bored.
Italy:
This is more of a ridicule of Mussolini himself. Or Italy after a really pro-UK Taranto dice mow -over.
ANZAC:
Quite true. The money islands are ANZACs biggest thing they usually can do…and Japan hates that.
France:
I object to explaining this one.
