I think you have a very good grasp on the strategy! Much better than when I first started, and probably even better than I understand it now ; P
You’re definitely very correct about Germany needing to maintain a good naval power in both Baltic and Meditteranean. Those are both extremely key to expanding in Africa and fending off the UK from raiding your coastal areas. I’d definitely hold off on building mass land units to go against Russia to keep these two locations. You will never ever be able to invade Russia anyways even if all you did was mass land forces, since your navies would be sunk and UK would raid your coast, forcing you to defend 3-4 coastal areas from possible invasions. And you’re correct about building lots of infantry to start with, both to replace the tanks in defensive locations, and also because they move very slowly so you have some time to get them to the front before you have enough transports to move them straight to ukraine or karelia.
You’re also probably right about Norway falling quickly (uk can assault with 2 loaded transports, bombardment, 2 fighters and 1 bomber first turn). However you can choose to defend it a bit more with fighters or your initial transport ferrying a couple more infantry there. Even though it’s 3 IPCs, you might want to make him pay for it.
You should also probably play till 9 victory cities. This is the accepted standard in tournaments because 8 obviously favors Axis too much, and 10 favors Allies because their last victory cities are extremely well fortified and delays the game immensely.
Also I noticed one somewhat wrong thing about your proposed Japan strategy -
Transports are superior to Industrial Complexes because not only can they mobilize more forces into the Mainland, but they also leave a constant threat of invasion on Alaska, further splitting the American Juggernaut’s IPC expenditures, or at the least forcing a garrison.
Transports are definitely not necessarily better than industrial complexes. TTransports are definitley very useful to build on your 1st/2nd turn to give you mobility in invading Australia/Alaska and get your stuff off of mainland Japan. However, if you ever want to truly threaten Russia, then you absolutely must have an IC on the mainland. This is because transports create a delay for land units, since the loading/offloading takes away their entire move for the turn.
For instance, if you have 2 transports lets say vs 1 IC on the mainland. With the transports, on the current turn you build 2 tank 2 inf. On the next turn, you transport them to the mainland. On the turn after that they can start moving. This creates a whopping delay especially for infantry who can’t keep up. However, if you had the complex on the mainland in indochina, you can buy 3 tanks. On the next turn they’re already able to move around, whereas the transport method they would just have landed and have to wait for next turn to move.
In the very beginning you definitely need transports to get things moving, but for long term invasions into Russia you must get at least one complex on the mainland. I actually get 2 - one in India as well. Once you get the US navy under control you can put out 6 tanks per turn, which presents a major threat to the Russians and even Africa. The IC in India also lets you build a fast battleship or transport and unload in Africa very quickly whereas if you build stuff in Japan it takes a while to get there. Yeah, building the IC itself might basically cost you a turn because it costs a bunch, but in the overall run it speeds things up immensely.
Also sometimes you absolutely need your tranports elsewhere invading islands or helping you take hits on defense. In this case if your transports are sunk, then you have no ability to get units on land within any reasonable amount of time. This makes your attacks heavily delayed on Russia, which is bad since usually Germany needs you to rear-end Russia a bit so it can live. Not to mention that transports can’t carry more than 1 tnak or inf per one, whereas you can buy up to 3 tanks at once at in IC.
Other than that you have a very good grasp on the actual problems that Germany has. With Japan also once you do pearl harbor II then keep an eye on your options; I usually gun down straight for Australia quickly while the US is building up again; use the battleship/carrier and the transport to quickly annihilate the garrison, and if you fail on the first run then just take your transport and get two guys from the surrounding islands and bombard again. Also with Japan be very aware of how many fighters you have. Immediatley turn them into a huge land assault force if the US navy isn’t threatening; it can really ram Russia in the butt if you get it going with some land troops.
From there you just want to keep a wary eye on the US transporting into Africa behind your back and the UK building up its own carrier to defend itself. You won’t be able to easily sink his Norway landing force if he himself gets a bigger navy. Just try not to lose your Baltic navy or you’ll suddenly find yourself playing in Russia’s position, which is defense. If you do lose your navy then you need to build fighters to sink his navy.
