Russia: Nothing but Infantry unless you would end up with 2 IPC’s left. If no-attack on round #1, then everything but 1 Infantry into Karelia and pull all out of the soviet far east save 1 INF for a strong counter attack. If attack on round #1, attack the german navy for sure, make him lose fighters for sinking the brit navy.
Germany: I’ve found that lots of infantry pays off towards later rounds, depends on the foe. I’ve played 200 times over 20 years, the germans and the russians stalemate, the brits and the US threaten the german coast while bring troops via finland. Lots of infantry means low value targets along the coast with high defense. Sink the Brit navy on turn 1, go all out. A varient, build 1 transport south, hit egypt with battleship, transport maybe air support and hope for victory against the brit sub, take egypt so allied air can’t attack navy and land, keep fighter in range of gibralter if the bit bomber needs to land there to kill german transport…… If all goes well it’s too costly to sink the german south navy, get some forces into africa and nurse it for IPCs. By T3 or so no more forces to africa unless cake walking in europe. Long term goal is to survive long enough for the Japs to crush. Keep bomber in western europe to smoke undefended transports on US coast.
Brits: You should end up with 1 transport off Canada and 1 off India, the rest is sunk and hopefully you took some german air with it. Either build 1 carrier and 1 transport, move in transport from Canada, move in US transport on US turn, USA flies 2 fighters to brit carrier. If the german position is too strong, save all your cash and build a bigger navy next turn. I’ve waited until turn 3 to build the brit navy and save all my cash the prior 2 turns. This requires the US to commit 50-75% of her resources.
Japs: Not a big fan of factories early on nor pearl harbour. Japan has good air power but needs cannon fodder ie infantry on land. A factory becomes an anchor, you must protect it, then build an AA for it. If you build factories, you build tanks with 'em cause you only build 3 units/turn at best with them. Build 2 transports and 3 infantry on round 1. Optimise their use, remember to take 1 infantry off a close island and 1 off Japan. 4 transports moves 8 infantry per turn on the mainland, Japan can’t build more than that until round 3 and latter. Save any excess money after 8 infantry per round then build a 5th transport. Now you are moving 30 IPC/turn onto the mainland. You don’t need any more transports. Your fleet should always move between Japan and Burma, move to burma and drop off infantry, then move the fleet to Japan and drop off infantry in Manchuria. Sooner or later you will see a huge opportunity to move the fleet from burma to africa, even if you don’t, the allies must defend the threat… If you must tie up your transports for fleet defense (cannon fodder) or your transports are in africa dropping off, then build a factory to take up the slack production. Japan must maximize it’s threat potential causing allies to use resources defending your options. Do this while always getting infantry to the contintent via transports. As the game progresses build 1 or 2 factories to get tanks to bare quickly. How often have you seen the japanese use tanks for fodder? If the german player is a rock of infantry stability you can crank you income to silly levels, make the russians defend russia. A huge allied multinational force is great on defence useless on offense, think economic victory…
United States. Logistics, Logistics, Logistics… The main key is bring troops over with british help to finland. You have transports in england, they move to Canada and load, move to england and unload in finland, it’s a long supply line, the sooner it gets going the sooner you threaten the german coast and get units onto karelia then against the Japs. If you build 1 transport on the east coast you must build 2 loads, 1 to go with it and 1 to move to Canada for next turns pick up. Build 2-3 transports on the east coast (watch for german bomber in west europe) and lots of equipment, plan your supply line. Sooner or later the british must move their fleet to land units on africa, you will have to move your fleet as well, a good time to have tanks in Canada to pick up and drop off in Algeria.
Allies: With good allied logistics you don’t need any strategy. Just outproduce, tie up the axis forces with threats, play conservative and avoid mistakes or close battles. Keep an eye on Japanese expansion in Africa, keep a tank or two there as ‘safties’. Build infantry, transports move 2 per round, once the supply line is set up the US brings over 8 infantry and a tank per round, the brits maybe 1 tank and as many infantry per round as IPC’s permit. Slip a few allied units with the russians to open opportunities (knock out the 1 infantry blocking the way to 2 bombers behind…) but stack most of them on karelia freeing the russians to repel the Japs.
Axis: Prayer… All out attack on the brit navy by the germans, milk africa for IPCs stay alive for the Japs. Japs must think expansion always.
