Netherlands setup AI

Netherlands Forces
4-3 INF, RES 3-2 MIL, RES 2-2 MIL, 3-2 TER, 1940 FTR2, 1941 LND3. 3 Naval units, 1 Sub, 10 CP, 1 TRS, 1940 2 Naval units

Netherlands have two basic setups:

* Capital defence: Is just as the name suggests a setup where the Dutch
land unit is setup on Amsterdam.

* NEI defence: The Dutch land forces are setup on Batavia/ Palembang guarding against a future or current Japanese attack.

Netherlands has two extreme setups:

* Border defence: Is just as the name suggests a setup where the Dutch
land unit is set as blocking force against advance of land units leaving Amsterdam and Rotterdam empty for CW forces.

* Rotterdam defence: During bad weather is it might be possible for the Dutch land unit to setup on Rotterdam and forcing the attacker to wait to attack only from one hex or wait one impulse and the risking change in weather, loosing surprise effects and hence faced with the possibility of defensive shore bombardment/ground support etc.

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

Threats to guard against:
* Threat of paradrop on Amsterdam
* Threat of invasion on Amsterdam
* Threat of paradrop on Rotterdam
* Threat of invasion on Rotterdam
* Threat of enemy land units in Belgium

* Threat of having the land out of supply
* Threat of having the land overrun
* Threat of having the land unit disrupted
* Threat of a quick land advance to Amsterdam from the North east

Good hopes:
* Chance of intervention from controlling power

* Border Defence

This is real dangerous since the Germans have good tactical air to disorganize the non-elite Dutch unit. Simple flanking moves will let them put it out of supply and then overrunning the OOS, disorganized unit can be done by a single armor unit. The result is that Germany can walk into both Amsterdam and Rotterdam.

It depends on whether supply can be traced across the Zuiderzee to the North Sea through CW CP in this version of WIF? If supply is guaranteed then overrun will be very difficult at all but breakthrough moevement to Amsterdam will be more or less automatic.

Is supply can not be traced across the Zuiderzee then I think this setup should only be a viable choice in whether different than clear?

Your right, weather is a consideration I hadn't thought about. The Zuider Zee is a lake, so unless it is frozen, supply can not be traced across it. The North Sea does not connect to the Zuider Zee, despite the 'canal' hexside (named Afsluitdijk?).

* Capital Defence

There is a variant to this, if the weather is Rain, and the No ZoC optional is not in play, and the Germans have no possibility of Invasion of the Dutch coast, and no possibility of paradrop on Amsterdam, and Belgium is still neutral and was not DoWed too.
This is to setup the 4-3 INF on the resource.
The ZoC of the Dutch unit block any German advance, and the rain prevent any breaktrough, as well as giving a -2 penalty (2d10 CRT) and a lesser chance of ground strike.
With this setup, none of Amsterdam or Rotterdam can be German at the end of the 1st Impulse, and the CW can consider reinforcing with 4 units and prevent the Dutch surrender, and maybe gain an US Entry for supporting a minor country.

This seems like a lot of conditions, but for a German attacking soon (S/O 39 or N/D 39), this have a lot of chances to happen).

The Zuider Zee is a lake, and CP in the North Sea are irrelevant to the supply of the hex where there is the resource. This hex is not coastal, and can't be in supply from the sea.

Overruning this Dutch units under rain needs a German ARM unit with 6 movement points (2 MP for the first hex, and 4 MP for the overrunned hex) adjacent to the Dutch Border. Just add this to my list of conditions for this setup to be used.

*NEI Defence C

This setup is particulary clever IMO, because a lot of Japanese players prefer to simply invade freely on the Oil fields of the NEI, securing the capital city later, to immediately have this oil to reorg just at the end of their onslaught all around invasion turn.
The Swamp and the city makes Palembang a particulary difficult spot to invade.

* Capital defence: Is just as the name suggests a setup where the Dutch

* NEI defence: The Dutch land forces are setup on Batavia/ Palembang guarding against a future or current Japanese attack.

I think that the Netherlands should never leave their home country as a freebie for the German, because it can very often cause disruption and air units usage to take it. Also, setting up a land unit outside the Netherlands means that one less naval unit can be setup outside the Netherlands,and Ducth Naval units come VERY handy for the CW player to help him all around.

Moreover, the NEI have already 2 units to defend their land with. The Batavia MIL and the NEI TERR.

So I'd never setup the 4-3 INF unit outside the Netherlands.

[Froonp]

Well, I do not agree with all this :

Threat of paradrop on Amsterdam:

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 Amsterdam or can be put in range of it AND

Can be put in range of Amsterdam ?
How ?
If an ATR is not in range from Amsterdam, it is out of range from Amsterdam, and can't be put in range from Amsterdam during this impulse. The Air Rebase Step is after the Paradrop Step, so there is no way the ATR can be put in range if it is not at the start of the Impulse (The only way would be Naval Transport, was this what you supposed) (which is right for the ATR, but wrong for the PARA, that CAN move to its ATR during the land movement step).

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 %

20% is a quite low chance to consider there is a paradrop threat, isn't it ?

THEN

There is threat of paradrop on Amsterdam

This is provided Belgium is still neutral I assume? After a French surrender there is no point in trying to defend the Netherlands to save 1 ship from being overrun....
