My mistake, SahintheFalcon, I didn't mention it is for SP. But still, thanks for the insight from MP, as it truly tests various theories.
I had not played HoI4 since, I think, July last year, when a line of two 7inf+2Art, SupAA divisions was almost enough to stop any AI, at that time forts had no meaning at all, but now, with much better AI templates, they work quite well in SP. Forts on italian border saved me 10-15 divisions (compared to my earlier playthrough, though I had more and better mountaineers too), so I'd say they were worth to build those 4 and using focus.On the other hand, extend the maginot focus was IMHO a waste, as those forts never came under attack.
I will definitely try only MIL production to check how it works, but I remember it worked well in my old games as Poland, when I only built 1-2 CIC before the war. Later I had German and Italian factories to make an army to defeat Soviets
The challenge in SP is that AI UK is very far from competent. You have to make planes, or you will not have air cover when you need it most. You need to import oil to make ships as you need to support UK at sea, or they will be crushed by Italians.
The only thing you can expect from it is to grind Axis planes over S England and English Channel.
You even have to cheat, as AI won't consisder providing you with LL of 30 naval fighters/bombers you need to replace losses on Bearn taken while you saved British Med Squadron from Italians, even though they have 600 such planes stored, AND you are providing them with 1000 rifles and some AT guns per month.
It will just waste troops in invasions - in the game I described above, UK decided to launch invasion in Gdansk and managed to loose 20 divisions there, while I was closing on Ruhr and Czech border from the south...
