Switzerland setup AI

Switzerland Forces
4-3 INF, 5-4 INF, 5-4 MTN, RES 4-2, RES 3-3 MIL 1940 6-3 INF, 1939 FTR2

Switzerland has four basic setups:

* Capital defence: Is just as the name suggests a setup where the Swiss
land units are setup to defend Berne.

* Zurich defence: Is just as the name suggests a setup where the Swiss
land units are setup to defend Zurich.

* City defence: Both Berne and Zurich is defended in this setup

* Mountain pass defence: All Swiss armies are setup between Berne and Zurich and north of the cites to cower all mountain passes

Switzerland has two extreme setups:

* Italian defence: In the event of attack from Italian soil only, are Swiss armies setup along the border to cover the advance to Zurich.

* Marauder defence: Is just as the name suggests a setup where the one of the Swiss units is set up to raise mayhem before Switzerland is beaten. The List of targets is: Milan, Turin, Lyon.

Declaration of war
Given a CW/FR declaration of war (with or without US) and GE control of Switzerland OR a GE/IT declaration of war with and FR/CW control of Switzerland the suggested reasoning for the AI could be as below.

Threats to guard against:
* Threat of paradrop on Berne
* Threat of paradrop on Zurich
* Threat of enemy land units bypassing Switzerland by mountain passes
* Threat of enemy land units entering Berne
* Threat of enemy land units entering Zurich
* Threat of enemy land units entering Switzerland only from Italy

Good hopes:
* Chance of intervention from controlling power
* Chance of intervention from none controlling power
* Chance to try to step on facedown allied unit(s)
* Chance to try to step on facedown axis unit(s)
* Chance to capture a Factory

Threat of paradrop on Berne:

IF the Weather is Storm or Blizzard the no risk of paradrop

IF any of the countries at war has a:

Organized ATR AND
it’s in supply or can be put in supply AND
the ATR has range to Berne or can be put in range of it by naval transport AND
there is a organized PARA AND
it’s in supply or can be put in supply AND
the PARA has range to ATR or can be put in range of it AND
the PARA and the ATR belongs to countries that can cooperate AND
the chance of a successful paradrop is > 20 %

THEN

Threat of paradrop on Berne

Threat of paradrop on Zurich:
Same as Threat of paradrop on Berne but the target is Zurich

Threat of enemy land units entering Switzerland only from Italy

IF any of the countries at war has
A organized LandUnit AND
it’s in France or Germany AND
it can reach a hex in Switzerland in one impulses AND
it’s not blocked by ZOC. then there is no Threat of enemy land units entering Switzerland only from Italy

IF any of the countries at war has
A organized LandUnit AND
It’s in Italy AND
it can reach a hex in Switzerland in one impulses
it’s not blocked by ZOC.

THEN

Threat of enemy land units entering Switzerland only from Italy


Threat of enemy land units entering Berne

IF any of the countries at war has
A organized LandUnit AND
it’s can reach Berne in one impulses AND
it’s not blocked by ZOC.

THEN

Threat of enemy land units entering Berne

Threat of enemy land units entering Zurich

Same as Threat of enemy land units entering Berne but the target is Zurich

Threat of enemy land units bypassing Switzerland by mountain passes

IF any of the countries at war has
A organized LandUnit AND
it’s can reach the hex SE of Berne in one impulses AND
it’s not blocked by ZOC.

THEN

Threat of enemy land units bypassing Switzerland by mountain passes


Chance of intervention in Switzerland from controlling power

IF Controlling major power has a unit in any of Italy, Germany and France AND
it’s in supply or can be put in supply AND
the unit can cooperate with Switzerland AND
the unit can move into Switzerland

ELSE IF Controlling major power can railmove a unit into Switzerland AND
the unit can cooperate with Switzerland

THEN

Chance of intervention in Switzerland from controlling power

Chance of intervention from none controlling power

IF none controlling major power has a HQ in any of Italy, Germany and France AND
it’s in supply or can be put in supply AND
the HQ can move into Switzerland AND

One of A or B

A)
IF none controlling major power has a unit in any of Italy, Germany and France AND
it’s in supply or can be put in supply AND
the unit can move into Switzerland

B)
ELSE IF none controlling major power can railmove a unit into Switzerland

* The Marauder defence
Is consider to be used when X and A, B, C and D

-- Lyon A
A) Lyon is controlled/conquered by the allies
B) There is no allied landunit in Lyon
C) The Switzerland 4-3 INF can reach Lyon in one impulse
D) The axis major power controlling Switzerland is at war France

X) The allies can’t directly rail/move or transport a unit to the hex that the axis want to reach and they can’t block the axis land units movement and the chance of a successful ground strike on the axis land unit it is less than 30%

A) Milan, Turin, Genoa or La Spezia is controlled/conquered by the axis
B) There is no axis landunit in the hex
C) The Switzerland 5-4 MTN can reach the hex in one impulse
D) The allied major power controlling Switzerland is at war IT

X) The axis can’t directly rail/move or transport a unit to the hex that the allies want to reach and they can’t block the allied land units movement and the chance of a successful ground strike on the allied land unit it is less than 30%

thanks for all your hard work, Mr. P...I doubt anyone has ever analyzed Swiss set-ups before, but it has to be done.

thanks for all your hard work, Mr. P...I doubt anyone has ever analyzed Swiss set-ups before, but it has to be done.

Has anyone ever done a Swiss gambit? It looks almost impossibly difficult.

Personally, I wonder whether the game doesn't model Switzerland as a bit tougher than they really would have been.

Peter,

We also need to consider the case where the Italians have advanced one hex into France before declaring war on Switzerland. Your Italian Defense 39 leaves open the possibility of just ruinning into Berne from the southwest.

EDIT: well, perhaps that is not very likely since the French will have ZOCs eveywhere. But there is the possibility of the Italian mountain unit crossing the alps and getting next to Berne - and concurrently cutting the Swiss off from Berne.
