MarineIguana has great advice. I have never played the allies against a german player playing that good (so I have always won as the allies)
If my experience is anything to go by, this is how the allied side of the board would look like.
In UK1, you can expect a UK counterattack on egypt, and depending on how the initial battles go, you can expect a UK landing in morocco with 4 units, being followed up by with 4 american Units. the allies will shuffle units into africa continously to the tune of about 8 US landunits and 6-8 UK landunits with some times a UK fighter.
The allied landunits will make their way across africa, lockind down africa south of sahara and continue east. In my experience I am able to get 1-3 allied stacks though persia into caucasus before japan shuts that path down being able to killzone it. for japan to be able to killzone it, the german stack on the other side needs to be able to bind the russian units in Cauc.
At some point, the allies will be expecting this shut down and swich their landingzone to norway. at this point, US will have one stack in W us, one in W canada. They will transport that W canada stack to norway every turn. The allied units left in africa will be staning in egypt, trading TJ with the japanese, making sure that japan cannot just snatch up africa. As long a TJ is traded, the allies cannot push their fleet though and threathen the japanese moneyislands (A deadly move if japan is bad enogh to allow it).
The allied landarmies that then will converge on russia will be massive, if the allies are strong enough to be able to lock down cauc and Russia with their landbridge to norway, and at the same time being able to hold on to africa, then the allies will win. If the axis are able to take cauc, then the axis will win.
This means: Build soooooo much infantry. I have had much more than 400 units in cauc with the allies.
To counter this, you will proabbly need 1-2 japanse factories on the mainland. If japan has 45+ IPC (not uncommon), and two factories on the mainland, they can build 3 art and 11 inf every turn. (which they should). at the same time, USSR will build 8 inf (24 IPC), and uk will land 6 inf + 1 ftr (28 IPC)and us will land 1 art, 1 tank and 8 inf (33 IPC). This means that the allies build about 23 units in this scenario, while Japan build 14, and germany has to build at least 9 to be able to match this.
One general point that I didn’t touch upon: the german /axis airforce and the allied fleet dynamic.
The allied fleet will be a number of fighting ships and a number of transport ships. the size of it, compared to the biggest airforce in europe (usually the german) is extremly important. The most important question is: How many places can the allied fleet be at once. For example; if the allied fleet is; 2 BB, 2 CV, 1 DD and 9 TTs, then the allies can make two fleets, the weakest will have 1 BB, 1 CV, 2 ftrs and 5 TTs. If the german airforce is 5 ftr and 1 Bomber, then the allied fleet can stand in two places, if the german airforce is 6 fighters and 1 bomber, then the allied fleet has to be in one place, and if it is going to split, one of its components has to go to the north sea where uk can build ships for it.
the general concept is; every german plane, will force the allied to use about 12 IPC on fleet for EACH of the fleets if they are going to try to stand two places.
Now to the second half of the dynamic; allied landingpotential.
If the allies can stand any place they want on the sea, they can land any place that they want. this means that you can start to expect a landing of 1 inf every sinlge turn in either normanie or italy, and a landing every single turn in places like estern europe, karelia or ukraine. This distruption is fairly dangerous for germany. germany will have to use their airforce with 1-2 infs to take the terr back, this means that the allies can skirmish back again (with BB support btw). These types of schirmishes is extremly draining for the german war economy and is why you will probably have that huge stack marineiguana talked about going back and forth. If it goes back and forth, you will still have the allies landing in s europe/normanie for free and killing 1 ipc on defence, while collecting 6 ipc of income every turn. This is a game that is not good for germany.
I am not saying you should go overboard with the german airforce, just enough to keep the allies honest and make sure they cannot land with impunity.
^^this ofcourse assumes that the allies main plan of attack is to build a landbridge. If their main plan is to build 40 US TTs and threathen to land anywhere, then you should buy 0 planes. then you should only have the 3 big stacks, 1 in germany to prevent landing there, one in w europe/S europe to make sure you are able to kill anything landing and still having enough in germany and the last one in the east to make sure the russians don’t get to much.
MarineIguana, am I correct in my experience?
