With the allies, the key to have a chance:
Be as aggressive as you can without risking to lose big capitals or vital points like Egypt or the Middle East, force the Axis to take chances with battles of attrition.
You start with a TUV advantage and an income advantage so trading equally or slight unfavorable trades are fine. You will never have a single nation able to compete with the Germans or the Japanese on the continent, so you have to force many small battles “guerilla style”.
Despite best Allied play, similarly skilled Axis play will usually beat allied play without a bid, but Allied victory is possible without a bid if there is enough luck involved.
The Guerilla style includes:
- Scrambles that improves the TUV swing
Intercepts of enemy raids (don’t lose Russian air force)
Dropping subs in convoy and constantly taking down the destroyers that come sweep the destroyers. If possible clean up the Med and convoy, convoy.
Straffing of German, Japanese or Italian units with allied aircraft.
Attacking with infantry. E.g., using two Chinese infantries to try to pick up one Japanese Infantry.
Trading time for position. E.g., lure the Japanese into a positive TUV battle that puts them out of position, combine that with pressure elsewhere that gives you local parity or superiority. E.g., Stack Yunnan while bringing Russians back to Amur while taking Islands and leaving naval targets to strike. Japan can definitely crush any one of these targets, but if they go after all of them they will bleed.
