Lets say you were playing as Britain (my favorite country to play as) and WW2 breaks out. You have 500k troops and 350k of those are reserve. Where will you send the majority of those? (Keep in mind that you have none in France and none in Africa) Personally I am in a game right now with a friend in HoI3 and I had 200k in Africa and 123k in Europe and won in Africa due to keeping the Italian fleet out of action but the new AI may be better in HoI4.
