So Stressful
Just when I thought I had the game mechanics down something else comes up. I'll try and be as informative as possible so bare with me. Any tips or advice will be much appreciated.

So i think I have the production part down. Its the warfare, mainly invasions, I am having trouble with. I am currently focusing on my pacific assault. More specifically, I am invading saipan from Guam. It took a couple test runs before I thought I had it down. So I shipped 22 infantry units to guam and started planning a naval invasion for that little island between guam and saipan.

Attempt 1: I couldn't execute plans because all my naval units returned to base for repairs after a huge battle.
Attempt 2: I got naval and air superiority, or close to it, in the Mariana region. I began to execute the plan but I guess I could only move 11 divisions instead of the 22 I originally planned. I dont think I met any resistance because my divisions are just standing still on the island not doing anything. Heres where the confusion or my noobism starts. The island my 11 div are on is now flashing "low supply" and the fuel cannister shows "11/3" but its still considered foreign territory so I cant add infrastructure. However, for some reason, I can build up the naval yard. The invasion is pretty much at a standstill I think. I even tried sending 8 of the div back to guam so the supply wasn't low but once they get to Guam they just hop back on a boat and go right back to the invasion.

Another thing I tried was splitting up the 22 div army with the units that were just waiting or had the red "!" next to them and creating another naval invasion on the main island of Saipan, but it wont do it. Even with a different, the new army is still connected to the other naval invasion.

Sorry for the long rant but I think I covered all my issues. What am I doing wrong or what don't I know? Thanks again for the feedback.

Oh also, if you have any tips on how to start the Europe or Africa invasion or which one to do first, that would be much appreciated as well.

Make sure you have reseached advanced landing craft, this is frequently missed by players as it is found at the very bottom of the ship research page below submarines. The number of units you can assign to naval invasions will be limited if you don't research this, further more you will not be able to execute simultainious naval invasion orders because your limited naval Invasion craft will be tied up for the first. Not only that, invasions will tie up convoys from the moment the order is placed till the moment it is sucessfully executed, so be carefull if you do not have many convoys stockpilled, if you use them all up you will not be able to move troops around nor get supplies.


You may only execute 1 naval invasion from each port, be it your own or an allies. So don't stack invasion armies in the same port. Unless of course they are follow up forces that you will land at a taken port after a successfull invasion.

To keep those units on guam, place a fallback order there and assign them to it, they can still be in the invasion army this way but they don't take part in the order / get in the way.

Supply on those pacific islands is very low, most of them are only level 10 bases so don't dedicate huge forces to taking them, they're mostly left unguarded anyway.

As for the invasion of Europe / Africa, what country / faction and is this aginst the AI?

No problem.

Against the AI, kicking the Axis out of Africa severly dents their resources but truth be told it's is not terribly important to winning the war, nonetheless the key to doing it is the Suez Canal and Gibraltar strait. To even enter the Med in the first place you need to hold at least one of those, ideally Gibraltar as it is closer, moving troops around south africa takes months otherwise.

If Spain went Facist they will eventually declare for the Axis. When that happens the strait of Gibraltar will be contested and impassable untill you take Morroco. Spain will also try to take Gibraltar which AI Britian frequently leaves unguarded. So Station forces to hold Gibraltar and ready to take Morroco to keep the Strait open. If you lose all sea access to the med when you have forces stationed there, they will be cut off from supply and start taking attrition. So be careful.

Taking North Africa is quiet simple, take all the ports on the nothern coastline between the Suez and Gibraltar, once you do that all Italaian forces there will start to take attrition as they won't be supplied. The front along the coastline is mostly 2 tiles wide so it there's not much strategy involved here, try to overwhelm the enemy and push them back / encircle with fast moving tank divisions. There is virtually no infrastucture / ports are of low level so be carefull not to send too many forces into the area or else supplies will be stretched. Like I said though, the key is Gibraltar and Suez, hold those and the rest just falls into place, often without you having to do anything as the Allies are usually competant enough to handle Africa themselves. I stress though, North Africa can be completly ignored even if it's entirely in Axis hands.

Europe requires a little more effort, but you have plenty of options, it's really up you you how to do it, you can follow history and deal with Italy first, wait for Spain to enter and then move on them, liberate any of the fallen countries or just land in northern Germany and take Berlin. The Key is usually the Russian Front. Wait for that to open up and then make your move, it ties up so many axis forces that it makes your job much easier. The difficulty is securing a port as they will usually all be defended, you'll need marines with high breakthrough to take a port directly But against the AI you can land forces either side of the port, surround it and then take it that way, it'll be much easier even though your troops will be without a supply line, once you take a port and you put enough forces on the mainland to hold it the Axis will never be able to kick you out. You can then slowly creep across france with your bottomless manpower reserves or you can breakthrough with tanks and encricle everything, up to you how adventurous you want to be.

Generally when I play allies I sort out Africa, take Italy then go for France (Cherborg) and Denmark at the same time. Not because they are the quickest strats to win the war, I just find it more interesting / they are good staging posts due to small fronts and good supply.

Also, Marines will give you quite a massive bonus as well so if your normal divisions can't do it, try with Marines.
