Sweden has one basic setup strategy:

* Region defence (Normal defence): Sweden is divided into regions and each region is given units to face the threat to it, depending on the size of the threat and the priority of the region

Sweden has two special setup strategies:

* Capital defence: Is just as the name suggests a setup where the Sweden
land units are setup to defend Stockholm.
- Primary Region: Stockholm

* Hero city Stockholm and Gothenburg defence: When faced with a mighty enemy the chance of holding the border is slim, the Swedish land units are setup around Stockholm and Gothenburg
- Primary Region: Stockholm and Gothenburg

Sweden has three extreme strategies:

* Attack Norway: An attacking force of units, not needed in defence against the current threat or factory defence, are placed near Norway to attack it if the chance is given.
- Primary Region: OsloBorder, NarvikBorder

* Attack Finland: An attacking force of units, not needed in defence against the current threat or factory defence, are placed near Finland to attack it if the chance is given..
- Primary Region: FinlandBorder

* Attack Denmark: An attacking force of units, not needed in defence against the current threat or factory defence, are placed near Denmark to attack it if the chance is given
- Primary Region: Malmö

Declaration of war
Given a GE/IT declaration of war and Western allies/USSR control of Sweden OR USSR/Western allies declaration of war and GE/IT control of Sweden. The suggested reasoning for the AI could be as below.

Threats to guard against:

* Threat of enemy land units entering Sweden from Finland
* Threat of enemy land units entering Sweden from Norway
* Threat of enemy land units entering Sweden from Denmark
* Threat of paradrop on/close to Stockholm
* Threat of paradrop on/close to Gothenburg
* Threat of paradrop on/close to Luleå
* Threat of invasion from Baltic Sea
* Threat of activation of Finland
* Threat of having the land unit disrupted
* Threat of a marine walkover from Åland

Good hopes:
* Chance of intervention from controlling power
* Chance to try to capture Narvik
* Chance to try to cut of Petsamo
* Chance to try to conquer Norway
* Chance to try to conquer Denmark
* Chance to try to conquer Finland
* Chance to try to conquer one of the Baltic states
* Chance to try to step on facedown allied/axis unit(s)

Simplified data for the setup script:

Threat Levels

Small: 1-3 DIV or 1-2 CORP/ARMY or 1 CORP/ARMY + 1-2 DIV
Medium: More that Small and less than Large
Large: 5+ CORP/ARMY OR 8+ DIV

Simplified logic of the primary rule of the setup script

1 Set the threat level for all Swedish regions

2 Calculate the number of units needed to meet the given threats for all Swedish regions

3 Calculate whether there are extra or too few units to handle all threats

4 Consider using a special defense

5 For all Swedish regions decide how many units each it is assigned.

5a If a Normal defence is chosen, modify allocation of defending units to each Swedish region depending on whether there are extra or too few units.

5b If a Special defense is chosen, the defence has coded how many of the available units the primary region(s) is assigned. The rest of the units are assigned like by Normal defence.

6 Sort all Swedish regions according to their threat level and priority

7 For all Swedish regions pick which units it is assigned.

7a Assign 1 poor unit to each region with a Small threat level, until there are no more poor units, or no more regions with a Small threat level. The purpose behind doing this is to limit the number of good or fair units given
to regions with a Small threat level. Note that this does not apply to
regions with a No threat level that have 1 unit allocated (e.g., regions with
a priority of 1 or 2).

7b Assign 1 good unit to each region with a Large threat level, until there are
no more good units, or no more regions with a Large threat level

7c Distribute any remaining units

8 The exact placement of units in each region is decided by a special AIO routine.

Regions in the northen part of Sweden

Regions in the southern part of Sweden

Example of a 1940 who a defence of Sweden could look like against threat from Denmark and invasion from the Baltic Sea.

the north

I suggest that maybe there should be a iron ore ressources defense.  Allies could be interested to DOW Sweden to take control of the 3 resources in the north, and deny them to Axis.  Historically Churchill has such a plan before the invasion of Norway by the germans, plan which was rejected by Chamberlain who was prime minister at that time.

The allies could invade Sweden if they are Norway already.

There is a build in iron ore resources defence in the basic setup strategy - Region defence (Normal defence) Se my first post in the thread for more info -. The region of NarvikBorder are likely to be used by the Swedish defenders when there are threat from the north of Norway. NarvikBorder marked with the yellow border on the image.
