In HOI4, what defenses do you build against invasions across straits?

[Revolution 11]

ThePatriotofDreumel, you convinced me that Denmark should be my first game.

Also, don't forget political power. In the 1939 scenario, you should pick ministers that improve army defense, organization, and entrenchment.

Also corporations! You should also aim to import as little as possible, you will need your civilian factories to quickly produce a lot of military factories. That means no motorised and planes, but you will not really need them in the war, since it will be a war with very little movement of troops, and Germany will probably eliminate your entire airforce, and later on the Allies can deal with the German airforce.

Yep! I was the one that made the Netherlands focus tree.

The best way to fortify Denmark would be to fortify the Danish islands, and focus all the industry in that region. Jutland will not be defendable, and the straits will function as great defensive regions. You should get the 5% recruitable populaion policy as fast as possible, as you will need tons of manpower. You should also make very strong units, with the best weapons possible, and as many bonuses to your army too. Hope that Germany has gotten into a fight with the Allies in the meantime, and just hold the line until Germany has bled to death trying to defeat you, with you having minimal losses.

I am even so nice to make some pretty good unit templates for you!

Germany plz no: Infantry division

Let's start with the support units: Military hospitals, Recon units and radio units. For the frontline units: 9 Infantry, 2 artillery.

Do not try to build an airforce, it will get destroyed. Focus all your military factories on building up a wartime supply of weapons, ammunition and artillery. You will not need any cavalry or tanks, but keep the templates around for when you start your counterpush and can encircle some German divisions in Jutland.

TL; DR: Fortify the straits, build factories in the Danish isles, get tons of manpower, abandon Jutland, laugh as the Germans get huge losses trying to cross the strait, bleed 'em to death, make a counterpush and realise that Berlin is already Russian, cry as you have gained nothing.

As for what fort: Naval forts, for if the Germans try to land in Copenhagen with boats.

EDIT: I think I just found my first game.

This is exactly the way I've played it in HoI 3, and that is why I am asking about the coastal forts. Clearly I am not the only one thinking this way

How will you achieve this? Will you look for political change?

No, when you go to war you can go to the manpower policies and for 150 Political power enact a policy that gives 5% recruitable population.

Then you should change your post to say that you will do it as quickly as possible after war is declared.
