This idea strikes me as insanity.

Costs:
1 fewer HQ in China, when the Japanese army really could use 1 extra
1 corp and 1 division not in China in 1939 when the ChiComs are at their weakest point
A 51% chance of adding a 1939 USE chit and a 9% chance of adding 2 chits. A 3rd potential chit if the CW moves in 4 corps. Even 1 extra chit is likely to speed up the embargo by a turn, not to mention the gear ups
A convoy line that is impossible to defend once the war starts with the UK

Gains:
1 oil resource per turn (until the CW and Japan are at war, at which point the convoy line is either pulled back or sunk).
2 Siamese units that you would have gotten anyway and which aren't useful until '41 (if even then)

Essentially, you're giving up inertia in China and hastening war with the US in return for a fairly small amount of oil, and the impact of the gain is blunted by the possibility of an earlier embargo, cutting off your other oil supplies.

(1) That is why Yamamoto is sent to China. Only if your are set on conquest of Saudi Arabia and not in it just for the oil. I would send 2 more combat factors to asure conquest of Saudi Arabia. Eventualy the CW will have the four corps for "Helping a minor".

(2) Yup. In 1939 the CW doesn't have the units if it is fighting Germany and Italy.

(3) Japan should be able to decide when it goes to war.

(4) Yes trading inertia in China for oil in Saudi Arabia. You are using the same arguments I used when this gambit was first suggested.

The realities of the expanded map to Japan's ambitions is really sobering.
Makes me wonder why the Armies of Japan and China were not also broken down into corps sized counters just like the European powers. It would have had my support. Maybe far into the future an expanded China & Japan counter mix could be researched and created as an option for MWiF. At least after NetPlay.

Japan did not use a corps structure just divisions and armies.

1939 Sep/Oct 3rd impulse (2nd Axis impulse)

Japan aligns Siam.
Japan makes a DoW against Suadi Arabia (Other minor).
From China to Saudi Arabia
1x CA (move 6 range 4) SCS transporting the 3rd division
2x TRS (move 3 range 3)
3x CP for the convoy line
1x Umezu HQ-I 5(3)2 (because he sets up in China)
1x INF 6-3
1x INF division 1-3

The plan is to attack the Saudi CAV Corps (if ever) after you get ashore not attack it when landing. A notational not in the ZOC of a friendly corps on the surprise impulse on clear terrain has a combat factor of zero and is an automatic successful landing.


The INF division invades from the 3 sea box.

If the Saudi CAV Corps sets up on Al-Jubail (or any other coast hex) don't land on or next to the Saudi CAV Corps. If the Saudi CAV Corps doesn't run back to Riyadh the INF division can threaten to take Riyadh.

If the Saudi CAV Corps sets up one hex behind the coast the Saudi CAV Corps is automatically eliminated at 9 to 1 odds.

If the Saudi CAV Corps stays in Riyadh the Japanese INF and INF division have 7 to 1 odds.

You don't have to attack Riyadh if you don't want to since all your here for is the oil. In that case if the Saudi CAV Corps sets up in Riyadh you could use 1x CA (move 6 range 4), 1x INF division and 3x CP for the convoy line.

1x oil per turn that can be stored in Bangkok (or shipped to Japan with one more CP) until Japan goes to war with the CW.


How does the CA get into the 3-box of a sea zone that is four sea zones away from China? (S. China Sea 1, Bay of Bengal 2, Arabian Sea 3, either Red Sea or Persian Gulf 4). That leaves 2 movement points and only gets you to the 2-box. Invading from there in any weather gives the notional at least a plus 1. Sending another Div on another CA adds another +1.

3 range TRSs won't even get close enough. All the hexes on the Arabian peninsula that touch upon the Arabian Sea are CW-controlled.

With an intermediate rebase to Mogadishu I believe (think it was mentioned).

Please find attached an artist's impression of the whole situation

That is how it's usually done - or Eritrea. But the "Case Orange" plan submitted made no mention...

With European scale it would be easier to go earlier, but regardless, aligning Siam is completely superfluous to this strategy.

Agreed. No idea how Siam fits in there. It is impossible to justify Siam without taking a shot at Malaya/Burma.

I guess I am confused here. I did go back and reread the thread.

But is the latest discussion about a Japanese attack on Saudi Arabia? Dunno why I thought it was a possible Japanese response to a USSR Invason of persia

The OP asked for advice on potential Japanese strategies. He's gotten some good advice and he's gotten some bad advice.

Yep. When I saw oil from that area I immediatly thought the persian Gambit with Japan and just ignored what was really written. As for this Saudi Arabia idea, I dunno about it being a good one. 1 oil is nic for certain but not if you let the Chicoms off the hook I would think

ORIGINAL: Centuur

To capture the Saudi Oil:

- Sail cruisers with divisions (the MAR and both INF divisions) on them with a convoy point into the Arabian Sea.
- Return to base to Mogadishu (Italian East Africa).
- Next turn, set up the convoy route (using the convoy point out of East Africa to go to the Persian Gulf) and invade with the divisions and MAR from the cruisers in Saudi Arabia. Make sure you got a TRS with an HQ sitting in the Gulf too, to prevent the Saudi's from setting up the CAV in the oil hex (if they do, land the HQ in the hex you've invaded and you can walk to the oil hex, killing the Saudi CAV).

Now, here are the downsides of this...

First: if the Saudi's set up the CAV in Riyadh, you can forget about conquering the country. Only if you put 2 HQ's in the country, you can get supply to be able to kill the Saudi's (lesson for everyone: always put the CAV in Riyadh).
Second: you need a corps on the oil to keep it save. If it leaves, the Saudi CAV can simply run across the desert and grab it back.
Third: US entry. You need to roll for the DoW and a smart CW player will try to get four corps in the country to roll again...
Fourth: as soon as war with the CW starts, the convoy line will have to be removed, which might telegraph your intentions to the CW.

So it can be done, only it doesn't sound advisable to me...



quote:

18. Co-operation
18.2 Not co-operating

Units that don’t co-operate cannot:
1. stack in the same hex, at any time that stacking limits apply; or
2. transport each other’s units; or
3. draw supply from a source controlled by the other; or
4. reorganise each other; or
5. be committed to any combat or mission that the other unit is, or
will be, involved in this step. This doesn’t apply to naval air or naval air interception missions.

Example: Commonwealth land units are in French controlled Liege. Jeremy cannot fly combat air patrol or interception with his FTRs over Liege during the strategic bombardment step because the factory is French. French aircraft could fly those missions to that hex during that step.

However, Commonwealth aircraft could fly ground support, combat air patrol, escort or interception missions to Liege during the Axis land combat step. French aircraft could not fly those missions because Commonwealth land units are involved.



19.1 Neutral minor countries
You can transport resources and build points through hexes controlled by neutral minor countries.
Your units can not enter hexes controlled by a neutral minor country nor can you trace supply through them (exception: Sweden, see 19.7 Axis minor countries).

quote:

19.7 Axis minor countries
Sweden
German units can move, and trace supply, into and through Sweden if Sweden is neutral and if there is at least 1 other German unit in each of Finland and Norway. If Sweden is neutral, no German unit can end a step in Sweden.


11.18.2 HQ reorganisation
A face-up HQ can reorganise units within range of the HQ. The HQ’s reorganisation range is equal to its reorganisation value in motorized movement points. The path from the HQ to the unit to be reorganised is traced exactly like a basic supply path, except its maximum length is determined by the HQ’s reorganisation range, and it may not be traced overseas. You may always trace 1 hex if the unit tracing supply is not prohibited from entering that hex. Lack of supply does not stop an HQ from reorganising units, or a unit from being reorganised.

An HQ has as many reorganisation points as its reorganisation value.

Turn the HQ face-down after it reorganises.


2.3 Stacking
There is a limit on the number of units that can occupy each hex. This is called the stacking limit of the hex.

2.3.1 Limits
Units that can’t co-operate (see 18.1) can’t stack together in the same hex. They can stack together in the same sea-box.

Stacking applies at the end of every step and after each retreat and advance after combat (see 11.16.5 Resolving attacks). You cannot voluntarily overstack then but if it happens (whether inadvertently or unavoidably), the owner of the hex must destroy enough of the overstacked units to comply with the stacking limits. You must destroy face-up units before face-down
units.

Land unit limits
You can stack 3 land units in a hex if the 3rd unit is a division, artillery or supply. (edited)



A minor point Centuur doesn't mention is that Mogadishu is the capitol of Italian East Africa a minor country aligned to Italy.

If Italy is neutral Mogadishu cannot be used as a base by the Japanese (see 19.1 Neutral minor countries).

If Italy is at war and Italian units are in Mogadishu Japanese units cannot be stacked in the hex (see 18.2 Not co-operating).

Assuming Italy is at war and no units are in Mogadishu the Japanese can rebasse there and be flipped. In order to use the HQ-I as Centuur suggest Japan needs to wait for Final reorganisation or use HQ reorganisation on the naval units. Using HQ reorganisation will turn the HQ face-down (see 11.18.2 HQ reorganisation).

Japan cannot use Mogadishu as a supply source (see 18.2 Not co-operating).

If the combat is done as Centuur suggests invading the hex adjacent to the Saudi CAV corps is

Japan
1x MAR division 1 combat factor
2x INF disisions total 1 combat factor
Total 2 combat factors

Assuming air support and shore bombardment 6 combat factors

2d10 Die roll modifications +1 the defending unit is a notional unit.


Saudi Arabia
A notional unit has 1 combat factor.
+1 if it is not stacked with a land unit, but is in the ZOC of a friendly corps.
-1 when surprised.

Total 1 combat factor.

the odds are 6 to 1 with a die roll modification of +1.

This is the same odds as directly attacking the Saudi CAV corps.

The HQ unit cannot stack in the same hex as three divisions (see 2.3.1 Limits) some unit will have to be eliminated or moved out of the invasion hex.

With the European scale map in MWiF, there are several hexes that can be invaded from the Persian Gulf that will neither be occupied nor in the ZOC of the Saudi Cav. With surprise, those are guaranteed attacks if from the 3-box in Fine weather. Unless the CW is willing and has a corps or two with transports that can get to ports in the Persian Gulf, then in a subsequent impulse, either Saudi Arabia gets conquered (and the oil is taken due to conquest) or the oil gets taken.

Before this can be done, Italy must be at war and must move any land units out of the port Japan wishes to operate from.

Ahhh. But the trick is to get the oil without getting losses. A notional unit has zero factors if it isn't in the ZOC of the Saudi CAV during the surprise impulse. Now, there are four invadable hexes on the Persian Gulf Coast line. You've got three divisions available for it. If the Saudi CAV is adjacent or on the oil fields, you invade the hex or hexes the CAV doesn't cover with it's ZOC to grab the two hexes the Saudi CAV can't cover (or the one if it is on the oil hex). Odds: automatic without losses. Now, the Saudi's have a problem, because next impulse, the Japanese will move a DIV into the capital, ending Saudi Arabia's resistance during conquest. Only thing countering this is the CAV leaving the oil hex for Riyadh or attacking the beachheads. If the CW gets a ship in the Persian Gulf, the CAV is in supply in a coastal hex and can attack (supply goes through Egypt on the railroad to Medina, a primary supply source for the Saudi's). Now, you need three division in the beachhead, beacuse there might be a counterattack and you need to survive that attack with at least one unit... If the Saudi's don't attack, here comes the HQ and the CAV is finished...

13.5.1 Oil (AfA option 48)
If you are playing with this option, you only automatically turn units face-up during the final reorganisation step if they are not oil dependent. To flip oil dependent units, you must spend oil resources.

Oil dependent units are shown on the Unit costs chart (see 28).

You can only use your own oil to flip your units face-up. Even oil controlled by co-operating major powers can’t help. However, communist and nationalist Chinese can use each other’s oil.

You do not have to transport the oil anywhere. But you must be able to trace a path from the unit to the oil resource. This path is exactly like a basic supply path (including via overseas) (see 2.4.2) except that it can be of any length.

Fourth: as soon as war with the CW starts, the convoy line will have to be removed, which might telegraph your intentions to the CW.



Japan
Sail to Mogadishu, Italian East Africa.
3x cruisers
1x SNLF division
2x INF divisions
1x CP

Wait for Final reorganisation to flip back the cruisers and CP.
Where is your basic supply path (see 13.5.1 Oil (AfA option 48))?

Next turn
Set up the convoy route up to the Persian Gulf.
Sail the CP from Mogadishu to the Persian Gulf to complete the convoy route.
Invade with the SNLF and two INF divisions.

Have a TRS with a HQ-I the Persian Gulf prevent the Saudi CAV corp from setting up in the oil hex.


"if they do, land the HQ in the hex you've invaded and you can walk to the oil hex, killing the Saudi CAV."
This violates Stacking limits.

You have a basic supply path to reflip your oil-dependent units if you play the basic supply rules. If you play LOS, it is all do-able as long as Japan has a 4-4 TRS.

Saudi Arabia has lots of hexes and the CAV can only be in one of them, so you can move a Div before landing the HQ (or pick it back up with another CA).

Personally, given the MWIF map, I'd try and do the job with 2 Divs and leave the HQ back in China. Without CW help, Saudi Arabia is doomed or the oil gets taken.

Personally, given the MWIF map, I'd try and do the job with 2 Divs and leave the HQ back in China. Without CW help, Saudi Arabia is doomed or the oil gets taken.


Yes, Saudi Arabia has lots of hexes and the CAV can only be in one of them.

You cannot pick a division back up with another CA before landing the HQ.

Because you are supposed to:
Embark durring the 11.4 Naval movement step.
Debark durring the 11.13 Debarking land units step.
Invade durring the 11.14 Invasions step.

Stacking applies at the end of every step and after each retreat and advance after combat (see 11.16.5 Resolving attacks).

There's no conflict with the sequence of play, the Div is embarked long before the HQ debarks. And there's no need for the HQ to invade.

The Divs did the invasion and are already ashore. We agreed on that. The HQ would be lucky to be in the 1-box on a TRS - from where it would likely die in an attempted invasion - even against a notional (since this is the next axis impulse after the axis impulse when the Divs invaded, and thus even a no longer surprised notional would be worth 1 plus the modifier for invading from a low box). The HQ only has to debark onto the now friendly hex the Divs are on - which occurs after both embarkation and land movement.

You've got it. Clean and simple that way. Only problem remaining is the Saudi CAV if they aren't brave. And let it be know that I would act like a coward with the Saudi CAV. "Run, you fools". In Riyadh it is hard to dislodge. If the CW leaves it on the coast, it is dead. Yamamoto and three division are more than enough to do the job.

Point is only that it is a foolish long term strategy to follow, since it can mean a lot of US entry to be added and the oil can only be held as long as there isn't war with the CW. After that, the convoy line can be attacked by the CW pretty easily...

If you are super jacked about 1 OIL, build your synth plant. If you are super jacked about mucho OIL, invade NEI prior to Netherlands aligning with CW -- this probably means no later than the second Axis impulse of the first turn. If you follow that conquest up with an immediate invasion of the Soviets, you are on your way to a "candle burns twice as bright" Japan game in which you might not win, but you will always be busy.

Now just exactly how do you get this:

The Divs did the invasion and are already ashore. We agreed on that.

The HQ only has to debark onto the now friendly hex the Divs are on - which occurs after both embarkation and land movement.




From is the post from Centuur just poorly written or what?

quote:

To capture the Saudi Oil:

- Sail cruisers with divisions (the MAR and both INF divisions) on them with a convoy point into the Arabian Sea.
- Return to base to Mogadishu (Italian East Africa).
- Next turn, set up the convoy route (using the convoy point out of East Africa to go to the Persian Gulf) and invade with the divisions and MAR from the cruisers in Saudi Arabia. Make sure you got a TRS with an HQ sitting in the Gulf too, to prevent the Saudi's from setting up the CAV in the oil hex (if they do, land the HQ in the hex you've invaded and you can walk to the oil hex, killing the Saudi CAV).




My post is exactly as he preposed it and you did not say my view was wrong then.

quote:

Next turn
Set up the convoy route up to the Persian Gulf.
Sail the CP from Mogadishu to the Persian Gulf to complete the convoy route.
Invade with the SNLF and two INF divisions.

Have a TRS with a HQ-I the Persian Gulf prevent the Saudi CAV corp from setting up in the oil hex.


Exactly how does having a HQ-I in the Persian Gulf stop the Saudi CAV corp from setting up in the oil hex?

Assuming the Saudi CAV corp gets to move how do you "walk to the oil hex, killing the Saudi CAV"?



You now have people trying to learn to play MWiF you need to be instructive on how to do it.

In order of battle:

Turn 1: 3 Japanese CRS (6-4 ones) sail for the Arabian SEa with three divisions on it. A convoy point sails with them. At the end of the turn they ALL return to base to Mogadishu and get reorganised there.

Turn 2, Japanese impulse 1. Naval action. Convoy points sail out of Canton and form a convoy line towards the Arabian Sea. A TRS (4 mover) leaves Canton with a HQ on board and sails into the Persian Gulf. The convoy point in Mogadisu is sailed into the Persian Gulf. The three cruisers with DIV's are put in the Gulf too).
Turn 2: CW impulse 1. CW sees the threat and moves ships into the Persian Gulf, Arabian Sea and Red Sea to make sure that whatever country Japan attacks (Persia or Saudi Arabia) any unit of that country will have supply on coastel hexes (unless the Japanese are stupid and DoW the CW too...).
Turn 2: Japanese Impulse 2. Land Action and DoW on Saudi Arabia. The divisions invade any hex not in the ZOC of the Saudi CAV. Automatic victory
Turn 2: CW impulse 2. Whatever the CW does with the Saudi CAV isn't going to make a difference. Either Saudi Arabia gets conquered if the Saudi CAV doesn't retreat to Riyadh, or the Saudi CAV gets destroyed next land impulse, because:
Turn 2: Japanese Impulse 3. The divisions move and so allow the HQ to land. It simply disembarks and if the Saudi CAV is stupid enough to stay on the oil hex, it gets blasted away with a 10-1 attack on it. Automatic victory. If the road to Riyadh is clear, one of the division captures the place...

This always results in the oil hex to get captured (being after conquest or due to an attack on the hex).

I think a missing strategy that needs mention is Persia.

Either as a defence to russian invasion of Persia, or as an attack.

Defense:
In this scenario, Japan reacts to USSR attacking Persia (for the 3 oil, typically followed by 2 more in Iraq).
Japan must get troops into Bandar Shapur ASAP, before Persia is conquered (not feasible to prevent). Japan must also DOW USSR before Persia is conquered. If this happens Japan can stay on in South Persia, and can usually hold on to 2 or 3 oil hexes (plus can get the one in Saudi Arabia).

3-4 extra oil early (they are controlled so can be used for reorg without transporting them) will do a huge difference for Japan. On the flipside, 5 extra resources for Russia early on (if Japan doesn't defend Persia) can make a large difference for the USSR.
IMHO, whenever USSR is set up for a Persia atack, Japan MUST maintain a capability to land land units in Persia on 1 impulse notice (i.e. alays keep a 4-move TRS + corps and/or 4-move SCS + DIV ready in South China)

Attack:
In this scenario, Japan attacks Persia for it's oil. Persia will typically align with USSR (CW is also possible).
The object is to grab as much oil as possible (conquest is normally to difficult).

The attack CAN be made directly from China:
-MAR-DIV(s) + SB + carrier air against typically Busher. very risky.
-auto-invasion of Lavan/Queshm. very slow

The better option is to invade via Somalia(similar to Saudi attack):
-auto div-invasion of any non-ZOC hex
-Invasion with Yamamoto/MAR + extra units + support vs defended hex.

DIV-invasion only is risky, Persia can set op NW of Busher and then rail/land a unit into Badar Shapur next impulse. This can end in no oil for Japan.

A (threat of) heavier invasion will normally produce a better result. Yamamoto (from 1 box) and 2 DIVs from 3-box + full support (NB: enough SB is difficult to get in range) will give up to 21 attack factors. The defence has a net +1 to the notional (-1 suprise, +2 low seabox). All targets are swamp/Mountain, so that's 4 defence for non-ZOC and 6 defence for ZOC hexes. After +1 for notional and +2 for HQ support odds will be around +13A (non-ZOC) or +9A (ZOC). Could be costly, but will normally get you ashore, maybe with some loss.

The ability for this last attack means that Persia should probably set up in Bandar Shapur (or SW of it if they feel lucky). This allows Japan to autoinvade Busher, and then land the HQ + support and attack the second oil overland. Japan can usually expect to grab 2 oil, but a lot depends on luck and how well prepared either side is. Japan has plenty of SB and full control of the air with it's carriers (both have little else to do at this stage of the game). Unless there is a DOW against Japan, USSR/CW units can not counterattack, don't have ZOC, and can't recapture territory. Japan can send DIV's running and threathen to cut off supply and rail routes.

Something's confusing me.

There's still no chain all the way back to Japan. Mogadishu only borders the Azanian sea, not the Arabian sea. Japan doesn't have any 5 moving transports on the first turn, so that means you can't even have a transport end up in the 0 box to keep you in supply.

Ergo, that means the Italians need to both be active, and to keep a convoy point in the Azanian sea. Given that they set up before the Brits, and won't be able to stay in supply themselves once they go to war with the CW, that means either doing a double DoW on separate impulses, or hoping that a few marauding cruisers don't shut down your operation.


The way you have it listed, with the transport coming out next turn, it means that while the Japanese units in Mogadishu might be in supply then, they're not when it comes time to final reorg on the first turn, so they'd all stay face down, right? Or are you having the transport you send out on turn 2 re-orging the convoy, and then sending him out to establish the supply chain? That still means you can't invade before turn 3 though.


Edited for clarity.

Edited for clarity.



That's only if you play with the optional rule Limited Overseas Supply. I don't play with that rule, because I have never understood why you need a whole convoy point for supply of one division. That's a huge overkill whereas having only one convoy point to get supply to two or three million soldiers is really something which is amusing...
WiF doesn't do a good job of simulating this using that rule...

Is this what you ment Centuur?

Turn 1
Any Japanese impulse
Japan chooses any action except Pass action
Two Japanese TF sail from Canton consiisting of:
TF1
3x cruisiers (6-4)(embarking the 3x divisions) ending the Arabian Sea sea box 0, 1, 2, or 3
1x SNLF division
2x INF divisions

TF2
1x CP sea box 0 the Arabian Sea

13. End of Turn Stage
13.4 Return to base they rebase to Mogadishu, Italian Somaliland (Italy must be at war)
13.5 Final reorganisation step they get reorganised there (assuming they have a basic supply path)

Turn 2
Japanese impulse 1
Japan chooses a Naval action

TF1
Sail from Canton to the Persian Gulf sea box 0
1x TRS (4-4) (embarking the HQ-I)
1x HQ-I

TF2
Sail from Mogadisu, Italian Somaliland to the Persian Gulf
3x cruisiers (6-4)(embarking the 3x divisions) sea box 4

Note: Splitting a taskforce has the same effect as the following.

TF3
Sail from Mogadisu, Italian Somaliland 1x CP to the Persian Gulf sea box 0 to form a convoy line.

TF4
Sail from Canton place 1x Cp in sea box 0 in South China Sea to form a convoy line.

TF5
Sail from Canton place 1x Cp in sea box 0 in Bay of Bengal to form a convoy line.

TF6
Sail from Canton place 1x Cp in sea box 0 in Arabian Sea to form a convoy line.


Allied impulse 1
If the Allies see the threat they can move ships into the Persian Gulf, Arabian Sea and Red Sea to make sure that whatever country Japan attacks (Persia or Saudi Arabia) any Allied unit on a coastal hex of that country will have supply (unless the Japanese also DoW the Allied power that controls the ships).


Japanese impulse 2
Japan makes a DoW on Saudi Arabia.
Japan chooses a Combined Action.
Land Actions do not allow invasions see 10.2 Allowable Activities chart.
The 3x Japanese divisions invade any hex not in the ZOC of the Saudi CAV corp for an automatic victory
Each unit which invades counts as 1 land move. Each invasion counts as 1 land attack. This leaves Japan with 1 land move and no land attacks.


Allied impulse 2
If the Saudi CAV corp set up on the oil hex it needs to move to Riyadh or it will be destroyed.


Japanese impulse 3
If the way to Riyadh is clear of enemy units one of the division can capture it.

The Japanese divisions have to move to allow the HQ-I to debark.

If the Saudi CAV corp remains on the oil hex
2x Japanese divisions can move adjacent to it debark the HQ-I there durring 11.11 Land movement and attack the Saudi CAV corp durring 11.16 Land combat.

Each unit which debarks counts as 1 land move and the TRS is turned face-down.


If the Saudi CAV corp is in Riyadh see AI for MWiF ~ Saudi Arabia peskpesk post#2 (map).


Each desert, or desert mountain, hex your supply path enters counts as 2 hexes.

If the HQ-I Japan sent was not Terauchi 6(2)3 (1937), Yammamoto 8(4)3 (1939), or Yamashita 7(3)4 (1941).
Any Japanese units that are adjacent to Riyadh will be out of supply and cannot attack.
