For Turn 1 as the UK player here are some ideas to preserve units and more importantly consolidate them for a powerful counter-attack. Before going further this article is meant to provide a reactionary strategy for a German bid for Africa and a potential aggressive Japan.
Purchase: 1 Industrial Complex to be placed in India. It is very important to have an ability to wage land war as the UK. India is an excellent option because Egypt is too risky, and India puts pressure on Japan while being able to reenforce Russia. This strategy will result in having a very large force in India and a large fleet off the coast of India. These tactics will give you a very strong foothold in India and should give russia a sigh of relief because you can get troops to their back door very fast.
Combat: Strategic Bomb Germany with your bomber from the UK.
Non-Combat Movements. This will be one of the largest tactical consolidations ever during your axis and allies experience.
Move 1 Infantry from W Canada to E Canada
Move 1 Infantry out of S Africa to Rhodesia (maybe)
Evacuate Egypt to trans Jordan, Persia, and India.(this means put your infantryman into trans Jordan, your tank in Persia, and your fighter in India)
Move 1 Infantry from Persia to India
Load 2 Infantry from Australia and move transport and submarine to SZ 30
Move fleet from India to SZ 30. Leave fighter on board carrier for now. This will allow you to have a fleet large enough to ward off any Japanese naval battle in turn 1.
Move Destroyer from Med to SZ 32. (This will be a great supporting vessel to your fleet in the Indian ocean)
Fly two fighters from Britain to Russia. (doing this bolsters Russias defense, but more importantly allows you to fly them to India on turn 2).
Transport 1 Tank from E. Canada to England
I would somehow link up the battleship you have in the Med with the one in the Atlantic. These can be used to deter Sea Lion attempts and to shatter the German fleet.
Turn 2
Purchase: 3 Fighters to put in India. Maybe purchase 3 infantry to put in GBR, or save money.
Combat:
Strategic Bomb Germany with one bomber
Possibly attack German atlantic fleet if it looks vulnerable.
You will want to unload the 2 infantrymen from Australia and the 1 fighter on your carrier into India this turn. If necessary use your fighters in India and your fleet to destroy the Japanese ships in the region. If there is no enemy fleet off of the coast of India then land your troops and consolidate your navy with the lone destroyer nearby.
Non-Combat Moves:
Move 1 Infantry from Trans-Jordan to Persia
Move 1 Tank and 1 Infantry to India from Persia
Fly Fighters from Russia to India
Transport 1 Infantry from Canada to GBR.
