If you are doing a KGF strategy, dealing with Japan isn’t the top priority. You’re just trying to slow them down and distract them. With the UK in India, don’t let Japan stack Burma. When they go in with land forces, hit them back. Have artillery in India.
I buy 1 of 3 options with the UK in round 1.
Carrier, Transport, 2 infantry, 1 artillery.
Carrier, Destroyer, 3 infantry.
2 Fighters, 2 artillery, 1 infantry.
Option 1 is if there’s minimal threat to the UK fleet. Germany builds a med carrier for example, loses fighters or moves them east. 3 or fewer planes in range.
Option 2 is if there are 4 planes in range. I’m not risking a transport.
Option 3 is if there are 5 or more planes/subs that can hit Britain. Build fighters in round 1. If they move away you can build a fleet in round 2. If they add more planes like building bombers, then wait until round 3 for the US fleet to arrive before building a navy. If Germany’s building that many planes, their army will be thin.
Basically I’m saying don’t focus all your attention with the UK on Japan. UK needs to be hitting Germany. It’s closer and easier to hit. The goal of the British in Asia is to harass Japan and delay them. Keep them occupied with India if you can. If they ignore India move up to Persia to block them from stacking Kazakh. A Kazakh stack is dangerous because it threatens Caucuses and Russia forcing Russia to abandon Caucuses.
With Russia, their job is to kill lots of Germans in the first 3 rounds. Don’t sacrifice troops but make Germany pay if they are overaggressive with Russia in a KGF. After the US and UK are landing in Europe just defend with Russia against Germany. Shift 90% of Russia’s focus to Japan and let the UK/USA deal with Germany. If Germany is stupid enough to keep attacking Russia and spreading themselves thin, they’ll collapse even faster.
With Japan, try to keep them out of any territories bordering Russia. If Japan is ignoring Russia mostly and focused 100% on India, move some infantry down to India. If it takes until round 5 for Japan to get India you’ve done your job. If I see India’s going to fall, I pull back the troops to Persia, then Kazach or Caucuses.
If Russia’s struggling use the UK forces to back up Russia. Russia has to stay alive. If Russia is fine, the UK India forces can head to Europe to take out Germany.
The USA should be totally focused on Germany.
