G40 Redesign (currently taking suggestions)

@barney:

so the AAcruiser is pretty badass for 10 bucks. You may be right that they’re underpriced Baron. 1 CA could potentially kill 3 fighters. Being able to send one in with a defenseless trprt where only air can counter makes one think about it. If you can pack a DD along even better. Pair it with a anti-sub carrier and it can do a little island hopping in the right circumstances.

I was thinking lower it to D2 and keep it at 10 bucks. Seems like the defensive fleet usually has the advantage maybe this would help. I’m gonna test them the same way a few more times and see what happens. I havent tried a CA spam yet.

The 10 bucks Cruiser was optimized in the OOB roster without adding anything else.
The balance formula between DD, CA and BB is:
1 DD A2 D2 C8 + 1 CA A3 D3 C10 = 1 Battleship A4 D4, 2 hits C18
You can try it by yourself on AACalc.
Add x DD + x CA on offense against x BB, you will always get pretty close to 50% vs 50%.
So, if BB is still at 20 IPCs, Cruiser with double AA should be put at 12 bucks.
Otherwise, Battleship becomes far less interesting purchase compared to DD and Cruiser.
Simply because for 20 IPCs, you get two 10 bucks Cruisers A3 D3, 2 Shore bombardment @2 and AA against up to 4 planes.
Just try 2xCA A3 D3 vs xBB A4 D4. You will see how it is too superior.
That is why I believe 10 IPCs AA Cruiser is OP.
Don’t make Cruiser defense same as DD.
It is weird from an historical weapon reviews.

yea that makes sense. So we’ll go with a 12 PU 2 shot AACruiser A3 D3 and bump his bombard back to 3. And for 10 PUs we’ll go with regular cruiser bombard at 2. And add a M3 version of the AA CA.

Barney:

I got Vichy France to work great.

Question: Would you have an ideas on how to code something like this:

Player captures opponent’s PUs only the FIRST time he captures his opponent’s capital. Subsequent capture of the same capital results in opponent’s PUs being destroyed.

So far I’ve figured out how to make it so that a player’s PUS are ALWAYS destroyed when the capital is captured (its a playerattatchment “destroysPUs”). But i can’t figure out how to make it so that this feature only kicks in after the first time the capital is taken. I’ve tried triggers that will switch on “destroysPUs.” I’ve tried conditions. Either I’m not doing it right, or playerattatchments can’t be conditional.

Any ideas?

Thanks.

Hey kid

**@Baron:

@Baron:

@regularkid:

Baron, how bout this for a simplified (closer to OOB) approach, that puts convoy raids on the attackers turn:

1. Warships and Subs may conduct convoy raids against any income producing territory bordering a convoy zone. This works similar to a shore bombardment, with each participating ship simply targeting a specific territory (No need for a rough division of damage between allied powers bordering the same sz. The attacker simply chooses each ships target).
**2. Surface ships can only make a raid in an empty convoy zone (if enemy ships are present, a naval battle results. No raid). Submarines can raid any convoy zone, unless enemy destroyer is present (if enemy destroyer is present, a naval battle results. No raid).

3. Convoy raid damage is determined using the OOB method, with each raid inflicting up to the value of the targeted territory.** The total amount of damage is immediately removed from the targeted player’s treasury.

4. Each convoy zone can only be raided once per round, per side.

Sound good?

At first glance it seems effectively a working alternative to Convoy Disruption nearer OOB mechanic.

#1doesn’t seem necessary. Once the damage are rolled, you apply the damage accordingly and let the owners split as they wish. The same way casualty are determined by multiple defenders.
The damage cap would be the sum of all enemy’s adjacent TTs to Convoy SZ.

It would be easier to implement into Triple A.

What do you do about Fighter rolling 2D6, keeping 1-3 as damage?
I’m OK with TcB.
Any idea about Strategic bombers?
In OOB Convoy system, every 1D6 roll gives an avg of 1 IPC, 2D6 gives 2 IPCs.
But getting no damage is possible, and there is no risk to the attacker.

What about letting StB rolling 1D6 and keeping 1-3 as damage?
1 IPC avg is much lower than 2.583 IPCs (or 2.916) avg on SBR.

Even if I try to develop a Convoy system similar to SBR, I believe that to increase action in ATO, there should be minimal danger against raider during his Convoy raiding phase.

So the OOB method: 1-3 = 1-3 damage 4-6 = 0 damage
DD, CA, BB roll 1 D6, CV have no dice, TcBs and Fgs get 2D6 along with Subs,
is my prefered choice. It imply no risk but there is 50% on 1 dice to totally miss.
That’s fine for me. Combat units must fight Subs to get ride of them.
Changing this phase into attacker’s turn makes it more efficient.
The more units are able to survive somehow from combat or raid, the more intense would be this theatre of operation. There will be plenty of units in many SZs.
That is why I prefer OOB raid, TP being able to escape on 2nd round, DD blocking 1:1 Sub, and only for one round, Sub cannot hit or be hit by submarine, etc.

Also, I’m actually working on developing Convoy SZs for 1942.2, so only Sub can do convoy damage in a way that it increase the losses for Allies vs Axis but the counter will be 5-6-8-9-12-15 cost structure, which I believe favors 2 Allied powers over 1 Axis power (Japan).

I will use Convoy rules to reduce UK and US economy, so buying cheaper warships would still be a burden due to IPCs shortage. I have hope this can balance things out.

Since the cost structure affect warships only, Russia have no Convoy SZ, so its economy cannot suffer from raid.

Now, I can provide a complete and still simple National Convoy Disruption House rule for 1942.2.
IDK if this mechanic can also works with G40.

First thing, the Convoy SZ is to be identify with owner’s Control Marker.
All Convoy SZs worth 4 IPCs and are bordering at least 1 TT or have an island group in it.
These TTs can worth 0 IPC to many IPCs, this doesn’t change the 4 IPCs Convoy SZ basis.

Here is all 1942.2 Convoy SZs I would implement (some such as SZs 2, 3, 45, 53, 57 can be considered as Allied lend-lease shipping SZs coming from either UK or US toward Russia or Australia) :

United Kingdom 31 IPCs
8 SZs x 4 IPCs = 32 IPCs max.
SZ 3 (Iceland), 7 (Northern UK), 8 (Southern UK), 10 (Eastern Canada), 23 (West Africa),
SZ 34 (Egypt, Saudi Arabia, Persia), 35 (India), 45 (North Eastern Australia)

United States 42 IPCs
9 SZs x 4 IPCs = 36 IPCs max.
SZ 2 (Greenland), 11 (US East Coast), 18 (Caribbean), 22 (Brazil),
SZ 53 (Hawaii), 55 (Mexico West Coast), 56 (US West Coast), 57 (Midway), 65 (Alaska/Western Canada)

Germany 41 IPCs
2 SZs x 4 IPCs = 8 IPCs max.
SZ 5 (Baltic)
SZ 15 (Italy)

Japan 30 IPCs
7 SZs x 4 IPCs = 28 IPCs max.
SZ 36 (Malaya), 37 (East Indies), 47 (Borneo),
SZ 48 (Philippines), 60 (Japan), 61 (China), 62 (Korea)

The most important thing to note :
lf at least 1 territory bordering (or the Island group within) the Convoy SZ is taken from his original owner and the Convoy SZ belong to the same owner, then this Convoy SZ is deactivated and can no longer be raided by enemy’s of the original Convoy SZ owner’s which have his control marker in this Convoy SZ.

When such Convoy SZ is deactivated, simply flip this Nation Control Marker face downward.

Only Submarine can raid Convoy SZ.

During Phase 3: Conduct Combat
Combat Sequence
1. Strategic and tactical bombing raids AND/OR Convoy Disruption

Each Submarine can either make a regular attack (Step 3. General combat) or a Convoy raid (Step 1. S&TBR AND/OR Convoy Disruption).
Even if there is warships (including DD) in Convoy SZ, Submarine can still make such raid.

Once the raid is done, Submarine cannot retreat and must stay in raided SZ.

Each 5 IPCs Submarine can make 1 IPC + 1 to 3 IPCs damage, by rolling 1D6: 1-3 = 1-3 IPCs / 4-6 = 0 damage.
So a single Sub always does at least 1 IPC damage (50% of the time, and more the other 50%).

There is no defense roll and Destroyer cannot do anything about it.
It is up to the Convoy SZ owner’s to send Destroyers (and more) on his turn to sink Subs.

These damage and odds are for:
5 IPCs Sub A2 first strike, D1 M2, damage: 1D6 (1-3= 1-3 / 4-6 = 0) +1 IPCs.
6 IPCs Destroyer A2 D2 M2, cancel 1:1 Sub Submerge and Stealth Move but not first strike.

If you want to play with OOB Sub and DD, then damage per Sub must be 2 IPCs + 1-3 IPCs.

The odds must be different because Submarine commander must see some benefits to not attack warships.
The odds for 5 IPCs Sub is 2/6 x 6 IPCs for DD = 2 IPCs damage on average.
1 IPC + 1-3 IPCs gives the same 2 IPCs average.

The odds for OOB 6 IPCs Sub are 2/6 x 8 IPCs DD = 2 2/3 IPCs
2 IPCs + 1-3 IPCs gives 3 IPCs average but the cap is 4, which gives 2 5/6 IPCs.
This is pretty close, and OOB Subs are lame ducks on defense vs DDs.

Damage are immediatly remove from Convoy owner’s hands, never more than 4 IPCs per SZ for the whole game round.

And attacker must put his own Control Markers (1 per IPCs damage) as a reminder for the game round of how many IPCs were raided if multiple raids occur from more than one alliance powers.

These Markers will be removed from the SZ during Convoy SZ’s owner 1. Purchase and Repair Units. Step 2: Pay for Units and Repair Damaged Units and Facilities.

Here is all AA50 Convoy SZs, 1941 set-up I would implement (some such as SZs 2, 3, 46, 53, 57 can be considered as Allied lend-lease shipping SZs coming from either UK or US toward Russia or Australia) :

United Kingdom 43 IPCs
8 SZs x 4 IPCs = 32 IPCs max.
SZ 3 (North East of UK), 8 (Southern UK), 9 (Eastern Canada), 17 (French West Africa),
SZ 34 (Egypt, Saudi Arabia, Persia), 35 (India), 38 (East Indies), 46 (Solomon Islands)

United States 40 IPCs
9 SZs x 4 IPCs = 36 IPCs max.
SZ 2 (Greenland / Northern UK), 10 (US East Coast), 18 (Brazil), 19 (Caribbean),
SZ 53 (Hawaii), 55 (Mexico West Coast), 56 (US West Coast), 57 (Midway), 65 (Alaska/Western Canada)

Germany 31 IPCs
1 SZ x 4 IPCs = 4 IPCs max.
SZ 5 (Baltic)

Italy 10 IPCs
1 SZ x 4 IPCs = 4 IPCs max.
SZ 14 (Italy)

Japan 17 IPCs
6 SZs x 4 IPCs = 24 IPCs max.
SZ 36 (South Malaya), 37 (North Malaya),
49* (Borneo), SZ 50* (Philippines),
61 (China), 62 (Japan)
*Deactivated on set-up.

@Baron:

From a gameplay perspective, this might be alright, but historically it misses the mark. Surface warships were frequently involved in convoy raids. Indeed,the Bismarck’s sole mission on its maiden voyage was to target allied convoys (Operation Rheinübung). This changed only when she (he?) was spotted and engaged by the Hood and Prince of Wales.

In the Mediterranean too, both sides often deployed surface warships to intercept enemy convoys.

I can see that this might conflict with a convoy-disruption mechanic that allows players to completely ignore enemy warships in a target sz, but I’m curious why you think that is necessary?

Attached is the most recent iteration of the G40 Balance Mod, incorporating the “Vichy France” event. Feedback welcomed.

**Global 1940 Second Edition - Balance Mod (with Vichy France Event) **

Original Game Credits: Bung, Veqryn

Revision Credits: Adam514, aznz, dss85, Gencre, regularkid

REVISIONS

Revised Air Raid Rules: Fighters attack and defend at 2. Strategic and tactical bombers attack at 1.

Revised Capital Capture Rules: The capture of a player’s capital results in the capture of his PUs only the first time his capital is taken. Subsequent recapture of the same capital simply results in the player’s PUs being destroyed.

**The “Vichy France” Armistice **

If Euro-Axis control both France and Normandy Bordeaux but have not yet conquered Southern France, all originally French territories (and their units) change ownership to Pro-Axis Neutrals at the end of Germany’s turn, with the following exceptions: (1) French Equatorial Africa and New Hebrides; (2) any territories containing non-French allied units; (3) French units in non-French Allied territory remain Free French. Liberation of France causes any territory still under Vichy French control to revert back to Free French control.

Note: Under the foregoing conditions, an Axis player may elect to bypass the “Vichy France” arrangement by conquering Southern France before or in the same turn as the Axis’s conquest of France and Normandy Bordeaux.

Impact on Axis National Objectives: Vichy French territory is considered “Axis” or “Pro-Axis” controlled for purposes of Italy’s “North Africa” and “Roman Empire” Objectives. Vichy French control of French Indo China does not impact Japan’s “Trade With America” Objective. Any direct takeover of French Indo China by Japan negates the Objective.

Additional National Objectives

UK

*3 PUs for UK Europe if Allies control at least 2 of: Sicily, Sardinia, Greece.
*3 PUs for UK Europe if Malta, Crete, and Cyprus are Allied or pro-Allied controlled.
*3 PUs for UK Europe if there are no enemy submarines in the Atlantic, excluding szs 112 and 125-127.
*3 PUs for UK Pacific when at war with the Japanese if: (1) British control West India and either Egypt or South Africa; and (2) there are no enemy submarines in the western half of the Indian Ocean (sz71,…,sz81).

USA

*5 PUs if Allies control at least 2 of: Normandy Bordeaux, Holland Belgium, Southern France, and USA has at least one land unit in any of these territories.
*5 PUs if Allies control Morocco, Algeria, and Tunisia, and USA has at least one land unit in any of these territories.
*5 PUs if USA is at war and controls Midway, Wake Island, Guam.
*5 PUs if USA is at war and Allies control Marshall Islands, Caroline Islands, Paulau Island, Marianas.

Revised National Objectives

Russia

*3 PUs for each originally German, Italian, or Pro-Axis neutral territory that Russia controls in mainland Europe.
*2 PUs for each of the following Lend-Lease lanes that is open if Russia is at war with European Axis and no allied units are present in any originally Russian territories: (Persia, sz 80), (Amur, sz 5), (Archangel, sz 125); An additional 1 PU per open Lend-Lease lane if Japan has declared war on Russia.

Italy

*3 PUs if Morocco, Algeria, Tunisia, Libya, Tobruk, Alexandria are Axis or pro-Axis controlled.
*3 PUs if three of Greece, Egypt, Southern France, Gibraltar are Axis or pro-Axis controlled.
*3 PUs if Malta, Cyprus, and Crete are Axis controlled.

I made this choice for simplicity and giving Sub its iconic econonic warfare value.
I also made a first working HR for 1942 Second Edition or AA50 1941 set-up, cannot say if it can be balanced or not.
IDK if such Convoy SZs mechanics can work in G40.2.
Since G40 is a more historically detailed game, I agree that surface warships will be part of any Convoy HR.

Revised Air Raid Rules: Fighters attack and defend at 2. Strategic and tactical bombers attack at 1.

This configuration has been tried during Alpha + game tests.
From a statistical POV, Fighter @2 is a deterent against SBR.
It is such, that Larry brings in 1942.2 SBR first strike @1 to bomber against Fighter defending 2.
But fighter also attack @1 first strike in this OOB SBR.

So, if you don’t like my optimized SBR rules to increase SBR, at least makes this little change to balance odds :

Fighters attack and defend at 2.
Strategic and tactical bombers attack at First Strike 1.
And let interceptors to hit bombers first.

@Baron:

Fighters attack and defend at 2.
Strategic and tactical bombers attack at First Strike 1.
And let interceptors to hit bombers first.

I don’t understand what you mean by “First Strike”? As for “letting interceptors to hit bombers first,” that is not something I would know how to program in TripleA. :(

@1 First Strike means that if interceptors got hit by bombers, they are removed immediatly and cannot roll on defense.

This works like AA gun First strike or Submarine Surprise Strike.

My hint to implement such on Triple A bombers is to use the patch created by Barney on AA Cruiser.
That way, you will get nearer my SBR balanced HR because it will gives bombers:
up to 2 AA @1 preemptive shots per bomber, 1 roll per Fighter max.

This provides better acceptable odds when there is either more bombers than interceptors or the reverse, more interceptors defending @2 than bombers.

The defending players will more willingly commit Fighter interceptors against an overwhelming number of bombers because it means 1 roll @1 per Fighter at most.

@Baron:

@1 First Strike means that if interceptors got hit by bombers, they are removed immediatly and cannot roll on defense.

. . .

The defending players will more willingly commit Fighter interceptors against an overwhelming number of bombers because it means 1 roll @1 per Fighter at most.

I don’t understand. If bombers can kill fighters by rolling a 1, and the fighters don’t even get to shoot back, why would this make defending players more willing to commit fighters?

Because it means 1 roll @1 per Fighter at most.
Players already accepts that AA @1 roll upon their planes.

If there is
A) 4 bombers attacking at a regular 1.
Or
B) 4 bombers attacking preemptive AA up to 8 Fighters.

If you have only 1 or 2 Fighters to intercept, A situation is more risky one.
A) 4 regular rolls @1.
B) 2 preemptive roll @1.

There is many calculations and tables I made to find the best equilibrium between offense and defense odds. (You can find some threads in HR forum, unfortunately a bit too messy.)
http://www.axisandallies.org/forums/index.php?topic=35883.msg1413631#msg1413631

Against Fighter-interceptor A2 D2,
giving 2 preemptive AA shots @1 per Strategic bomber is the most balance.
1 bomber can still take a risk against 2 Fgs @2, because it gets 2 first strike @1.
The defender have 2 Fighters Rolling @2 each. Without such AA roll, the single bomber must submit to 2@2 and 1 IC @1 before bombing IC.

On a gross avg 4/6+1/6 = 5/6 (83%) to be destroy before doing damage on IC.

Having AA shots gives a little more survival odds to bomber.

@Baron:

Having AA shots gives a little more survival odds to bomber.

So really what your proposing is to make strategic bombing less risky/easier? That’s not really a problem with the game.

For Global 1940 alternate Convoy Disruption House Rule.

Black_Elk quote is for the Devil advocate…
@Baron:

@Baron:

@Black_Elk:

Yes I think that does a pretty good job of sumarizing my misgivings, and contrast with the OOB situation. Also important to me is the ability to create one system that could work on all game boards.
Frankly I don’t like either system, because I think the economic disruption should be a feature of the submarine unit specifically (not all warships) and that this should be a form of “attack” made during the raiding player’s own “conduct combat phase,” not during the opponent’s collect income phase!
My argument there would be for simplicity and for gameplay i.e. as a way to make the submarine different from other naval attack units, and give it a more independent “hunting role.” I say the argument is “for the gameplay” because I’m aware that historically any warship could probably disrupt convoys. But what we’re looking for in a rule, is a way to separate off the role of subs and make that role unique or advantageous when compared to other naval units at a comparable cost. More advantageous than they are in normal combat, so players actually have an incentive to use them for the economic attacks instead of just normal attacks!

Otherwise the subs just default to the same way other naval combat units work e.g. grouped together with the main fleet, or the main air group. I don’t think the submarine should work like this. (I don’t think StratBs should work like this either, for that matter, even if this conversation is just for subs, I see them as related issues. I mean the way a bomber’s economic attack advantage is subordinated to its normal combat attack advantage vs ships, instead of the other way around.)

The sub unit would be far more interesting, if it’s primary role was for economic attacks, with a secondary role in normal combat. The current situation is basically the reverse. And the sub isn’t really very unique as a convoy disrupting unit. It behaves like all other ships that disrupt convoys, except that its cheaper for the spam and can’t be hit by air without a dd.

The analogy I always return to is SBR or Rocket Attacks, I think subs should work in a similar way. Either you choose to use them as a combat unit, or you forego combat for the chance at an “economic attack.” I think you should be able to run such a “sub attack” in any coastal sea zone bordering enemy territories with an ipc value, otherwise it only works on maps with a special “marker” or map designation drawn on the sz, which means it can’t work on all game boards.

A simple rule, that took into account the max value of adjacent enemy territories, and then allowed subs to “roll” against it, would be ideal. If its overpowered, then you just build in some kind of defensive roll, similar to an AAgun vs a bomber, to destroy the sub. I used to play with similar rules in AA50 (although there it was a special roll against coastal factories for my group.)

The danger of all convoy rules that allow you to “destroy” enemy IPCs directly is how they can affect the first round purchase options. Thinking about SBR as a model, when you “raid” with a bomber in the latest games, money is removed indirectly (via the purchase/repair damage system). In the old SBR rules of Classic/Revised a successful “raid” meant that your opponent had give money to the bank immediately, with no “choice” and no damage/repair. Seems to me that the G40 convoy rules follow the earlier sort of idea of Classic or Revised (where the money is given up to the bank ie. destroyed), even though I much prefer the latter sort of idea from AA50 and later, where the player got to choose how to deal with the consequences of the raid.

In other words, I don’t think players should have to learn two totally separate “economic raiding mechanics” one for bombers and one for subs. Instead the two mechanics should mirror each other and work in similar ways. If not exactly the same, than at least similar enough that I can explain one with reference to the other.

Putting the focus on coastal factories would probably be too overpowered, given how SBR already works against these factories. But if you’re not going to put the focus on coastal factories or give the defender an intermediate “repair” type option, but use the old model (money taken goes straight to the bank) then there should at least be a chance that the “raiding” unit can be destroyed during the economic attack, the same way bombers face AA fire, defender rolls at 1 to destroy the unit attempting to raid. I think that would be way easier than separating this whole “convoy” process out across multiple turns in the game round, which is what the current G40 system does.

I will assume my most preferred type of 5 IPCs Sub against 6 IPCs DD:

HR SUBMARINE A2 first strike D1 M2 C5 IPCs,
first strike even when enemy’s DD present, no first strike roll on defense (ever)
blocked by DD on 1:1 basis Stealth Move and
on 1:1 basis Sub’s Submerged for first round only.
Any plane can hit unsubmerged Submarine during combat round without any Destroyer presence.
(If a Sub submerge during first strike phase, plane can not hit Sub.)
Submarine cannot hit submarine nor aircrafts.

Convoy Raid Damage: 1 Dice keep all 1 to 3 results AND add 1 IPC

Immediately remove IPCs from enemy’s power.
Add 1 chip under National Control Marker in Convoy SZ per IPC damage (as reminder).

DESTROYER A2 D2 M2 C6 IPCs,
blocks on a 1:1 basis Submarine’s Stealth Move, CM and NCM, and Submerge, first round only.

I would also delete Bordeaux Convoy SZ 105.

1. Any Convoy SZ is to be identify with owner’s Control Marker.
   All Convoy SZs worth 4 IPCs and are bordering at least 1 TT or have an island group in it.
   These TTs can worth 0 IPC to many IPCs, this doesn’t change the 4 IPCs Convoy SZ basis.

Shared Convoy Sea Zone:
lf at least 1 territory bordering the Convoy SZ belong to an enemy’s Power, this Convoy SZ maximum is split in two 2 IPCs which can be both raided by the other side. So, some Convoy SZs could have two National Control Markers, one from Allied Power and one from an Axis power.

If multiple Powers from the same side share a common Convoy SZ, damages are split between these Powers, as they wish. (Same as multiples casualties in a TT or SZ.)

During Phase 3: Conduct Combat
Combat Sequence
1. Strategic and tactical bombing raids AND/OR Convoy Disruption

2. During Combat move phase, each Submarine can choose whether to make a regular combat attack (Step 3. General combat)
   OR
   to do Convoy Raid in a given Convoy SZ (Step 1. S&TBR AND/OR Convoy Disruption).
   It is only Submarine units which get this option, even if Convoy SZ is enemy controlled by warships.

Other warships and aircrafts (Destroyer, Cruiser, Carrier, Battleship) can only do such Convoy Raid if there is no enemy’s surface Warships in Convoy SZ. (Step 1. S&TBR AND/OR Convoy Disruption)

3. The Convoy Raid damage roll is determined that way: 1 roll 1D6 per Sub and keep only 1 to 3 results, and add 1 IPC to the result.
   (Odds: 2+3+4+1+1+1= 12/6 = avg 2 IPCs.)
   (@2 first strike = up to 3 damage roll)

It gives the amount of IPCs which will be lost immediately by Convoy SZ’s owner.
Never more than 4 IPCs per Convoy SZ for the whole game round.

You put in the SZ one Country Control Marker chip under the Convoy’s SZ owner National Control Marker for each IPC damage on Convoy to keep track of the entire game round results against this Power.

Other Combat units get only 1 single dice to roll, and get Convoy damage if they get their attack number or lower:
Surface warships:
Destroyer Attack @2 Damage on 1-2. (odds: 3/6 = avg 0.5 IPC)
Cruiser Attack @3 Damage on 1-3. (odds: 6/6 = avg 1 IPC)
Battleship Attack @4 Damage on 1-4. (odds: 10/6 = avg 1.67 IPC)
Carrier Attack @0

Aircrafts:
All empty Convoy SZs are treated the same as a Tactical Raid target.

Fighter have no attack on Convoy SZ.

Tactical Bomber (12 IPCs HR) takes a Tactical Bombing Raid 1D6 damage as usual but must first submit to preemptive AA defense @1.
(Odds: 18/6= avg 3 - 2 = +1 IPC. Regular AA)
(Odds: 18/6x 5/6 = 15/6 = 2.5 - 2 = +0.5 IPC. Preemptive AA)
(OOB G40 TBR D6: +2.917 - 2 = +0.917 IPC damage/TBR)

Strategic Bomber makes a Tactical Bombing Raid 1D6+2 damage as usual but must first submit to preemptive AA defense @1.
(Odds 23/6= avg 3.833 -2 = +1.833 IPCs. Regular AA)
(Odds 23/6 x 5/6 = 115/36 = 3.194 -2 = +1.194 IPCs Preemptive AA)
(OOB G40 SBR D6+2: +4.583 - 2 = +2.583 IPCs damage/SBR)

(This is played as an IC’s AAA. Many Cargo Ships were equipped with AA guns and were more able to defend themselves than against Submarines attack.)
In addition, the 4 IPCs cap in Convoy SZ makes such Tactical Bombing Raid sub-optimized compared to SBR and TBR on IC, Air Base and Naval Base, as you can compare above.

**Do you think this alternate National Convoy Disruption for Global 1940 can be a workable balance system?

Do you see it as a sufficient incentive for Submarines Commander to prefer raiding over regular combat?**

For Global 1940 alternate Convoy Disruption House Rule.

I will assume my most preferred type of 5 IPCs Sub against 6 IPCs DD:

HR SUBMARINE A2 first strike D1 M2 C5 IPCs,
first strike even when enemy’s DD present, no first strike roll on defense (ever)
blocked by DD on 1:1 basis Stealth Move and
on 1:1 basis Sub’s Submerged for first round only.
Any plane can hit unsubmerged Submarine during combat round without any Destroyer presence.
(If a Sub submerge during first strike phase, plane can not hit Sub.)
Submarine cannot hit submarine nor aircrafts.

Convoy Raid Damage: 1 Dice keep all 1 to 3 results AND add 1 IPC

Immediately remove IPCs from enemy’s Power hands.
Add 1 chip under National Control Marker in Convoy SZ per IPC damage (as reminder).

DESTROYER A2 D2 M2 C6 IPCs,
blocks on a 1:1 basis Submarine’s Stealth Move, CM and NCM, and Submerge, first round only.

Aircrafts:
All empty Convoy SZs are treated the same as a Tactical Raid target.

Fighter have no attack on Convoy SZ.

Tactical Bomber (12 IPCs HR) takes a Tactical Bombing Raid 1D6 damage as usual but must first submit to preemptive AA defense @1.
(Odds: 18/6= avg 3 - 2 = +1 IPC. Regular AA)
(Odds: 18/6x 5/6 = 15/6 = 2.5 - 2 = +0.5 IPC. Preemptive AA)
(OOB G40 TBR D6: +2.917 - 2 = +0.917 IPC damage/TBR)

Strategic Bomber makes a Tactical Bombing Raid 1D6+2 damage as usual but must first submit to preemptive AA defense @1.
(Odds 23/6= avg 3.833 -2 = +1.833 IPCs. Regular AA)
(Odds 23/6 x 5/6 = 115/36 = 3.194 -2 = +1.194 IPCs Preemptive AA)
(OOB G40 SBR D6+2: +4.583 - 2 = +2.583 IPCs damage/SBR)

(This is played as an IC’s AAA. Many Cargo Ships were equipped with AA guns and were more able to defend themselves than against Submarines attack.)
In addition, the 4 IPCs cap in Convoy SZ makes such Tactical Bombing Raid sub-optimized compared to SBR and TBR on IC, Air Base and Naval Base, as you can compare above.

Giving a preemptive AA @1 against TcBs and StBs trying to Disrupt a Convoy works as a simpler mechanics based on SBR and TcBR.

However, from a more realistic POV (there is no AA batteries floating on the ocean surface around merchants ships), it is also acceptable to give a regular AA @1 against StBs and TcBs on Convoy raid if such transport unit with a similar AA defense is used.
Both defenses, against raiding Convoy SZ and attacking unescorted Transports with Aircrafts, would imply similar mechanic.

TRANSPORT
8 IPCs A0 D0 regAA1 M2, 1 hit, taken as casualty according to owner’s choice.
Carry 2 units, 1 Inf + 1 any ground unit
No defense against warships,
Beginning on the second combat round, 1 Transport can escape from Naval Battle in the same SZ at each end of combat round, if there is no enemy’s aircraft.
Simply remove TP from battle board and place it in the SZ on the map.
Regular AA @1 against up to 1 plane, whichever the lesser.
Can unload in a Sub infested SZ if escorted by surface warships.

And odds for regular AA defense are not that high neither.

Tactical Bomber (12 IPCs HR) makes a Tactical Bombing Raid 1D6 damage as usual but must submit to regular AA defense @1.
Odds: 18/6= avg 3 - 2 = +1 IPC damage/TcBR vs regular AA
compared to
OOB G40 TcBR D6: +2.917 - 2 = +0.917 IPC damage/TcBR

Strategic Bomber makes a Tactical Bombing Raid 1D6+2 damage as usual but must submit to regular AA defense @1.
Odds 23/6= avg 3.833 -2 = +1.833 IPCs damage /TcBR vs regular AA
compared to
OOB G40 SBR D6+2: +4.583 - 2 = +2.583 IPCs damage/SBR

Here’s one with some changes. Returned Aleutians, Midway, Fiji and Samoa to 0 and HI to 1. Boosted West India back to 2. Iwo, Formosa and Okinawa don’t get the 1 PU NO boost.

Done about a half dozen tests with different DOW dates. The J1 still seems hard to save India. Might try getting rid of the Island NO and just give them all 1 at the start. IDK if that would discourage the J1 attack at all or not. I think India probably just needs a few more dudes. Don’t want it to be impossible but not a sure thing either. Oztea seems to have a pretty good balance on his.

Anyway here’s the new one. The previous ones are still available on the other posts.
