Bombing by Average

@barnee

Unfortunately, I couldn’t find anything from Der Kuenstler. Here is the piece Gen Manstein was talking about:

https://www.historicalboardgaming.com/Atom-Bomb-3D-Printed-x5_p_3707.html

You got me thinking on how now to force attacker to take a bomber instead of a fig in SBR dogfights. Thinking if interceptor rolls a 1 it forces attacker to take a bomber casualty. This way don’t have to raise defense on a interceptor. Just thinking here.

May add this to land naval combats to

Okay, it sounds reasonable then. As Escorts primary purpose (from a game play perspective) is to take interceptor hits instead of bombers (the ability to shoot down interceptors seems incidental in comparison), I’m inclined to pair it with a rule that escorts can each protect one bomber, but any unprotected bombers take interceptor hits first. This way at least you have a reason for intercepting escorted bombers.

Good to see you back. Thanks for reply. I do have what your talking about on old map and my new map. Axis control Belgian Congo receive 4 icps. Other 3 is from USA.
We don’t have the atom bomb but allies get to start game with these 4 icps but axis can get it too. Just a small house rule anyway.

This mechanics can also be applied to ABs as Carolina is suggesting:

Air and Naval base damage
@Carolina:

Great topic - hi-lights how A&A is a little too basic.  ie. not all hits should be equal - really, when would AAA blow every plane out of the sky?

I would propose to change the AAA rule for bases and industry that AAA does not kill but affects the accuracy of the attacker.  Defending installation rules a 1d6 and this is subtracted from the attacker’s roll.  
1d6-1 for fighters and tacB
1d6-2 for bombers
Roll an AAA dice for each attacking aircraft.

@toblerone77:

What is so hard to understand?

Three STBs make a night raid. The defender rolls three dice and scores 3 hits by a miracle.
So 1.5 hits rounded up, it’s two hits, rounded down it’s one hit. The remaining attackers roll for damage and the total is halved to the nearest IPC worth of damage up or down.
If some one were to use the HR their group could decide.

Want simpler rolls for AA guns during a night raid? Easy use D12 dice and have them roll at 1. That equates .5 pips on a D6 die. Easy.

You got it man!!!  :-o  I completely forgot about this possibility of using D12.

I believe you already play with D12, so it won’t be difficult to introduce it in your game.

Day and night AAA will be distinct this way:
Day AAA, use 1 on D6 or “1” or “2” on D12.
For an average casualty of 2/12 * -12 IPCs = - 2 IPCs/StB run.

Night AAA, use “1” on D12.
For an average casualty of 1/12 * -12 IPCs = - 1 IPC/StB run.

One casualty roll is always better. And you get your half casualty average for Night B.

The last point remaining is on damage roll of 1 StB.
Day time SBR:
D6+2 (avg 5.5) * 5/6 = 27.5 IPCs/6 =      4.583 IPCs/StB - 2 IPCs = 2.583 IPCs/run 100%
D6 (avg 3.5) * 5/6 = 17.5 IPCs/6 =          2.917 IPCs/StB - 2 IPCs = 0.917 IPCs/run 35.5%

Night time SBR:
D6 (avg 3.5) * 11/12 = 38.5 IPCs/12 =    3.208 IPCs/ StB  - 1 IPC = 2.208 IPCs/ run  85%
D3+1 (avg 3) * 11/12 = 33 IPCs/12 =      2.750 IPCs/ StB   - 1 IPC = 1.75 IPCs/ run  68%
D6-1 (avg 2.5) * 11/12 = 27.5 IPCs/12 = 2.292 IPCs/ StB  - 1 IPC = 1.292 IPCs/ run 50%
D3 (avg 2) * 11/12 = 22 IPCs/12 =          1.833 IPCs/ StB  - 1 IPC = 0.833 IPCs/ run  32%

Last Tob77 version 4 out 6 doing 2 IPCs damage:
4/6 * 2 IPCs * 5/6 = 40 IPCs/36 =           1.111 IPCs/StB - 2 IPCs = -0.889 IPCs/run - 34%

AA gun hits halved rounded up version for 2 StBs:
D3+1(avg 3)*11/36=33 IPCs/36=      +0.917 IPCs/ 2StB
D3+1(avg 3)225/36=150 IPCs/36= +4.167 IPCs/ 2StB - 3.667= 1.417/2= 0.709 IPCs/ 1 StB run 27%
                                                                            or -1.834 IPCs/ 1 StB

AA gun hits halved rounded down version for 2 StBs:
D3+1(avg 3)*1/36=3 IPCs/36 =         +0.083 IPCs/2StBs
D3+1(avg 3)235/36= 210 IPCs/36= +5.833 IPCs/2StBs -0.333= 5.583/2= 2.792 IPCs/1 StB run 108%
                                                                             or -0.167 IPCs/ 1 StB

1 StB against AAA repulse @2:
D3+1 (avg 3) * 4/6 = 12 IPCs/6 =      2 IPCs/ StB   - 0 IPC = 2.00 IPCs/ run  77%

Rolling damage first 1 to 4 IPCs, 5 or 6 is a miss and get under AA fire @1:
1+2+3+4+0+0=10/6 IPCs =         + 1.67 IPCs - [(12 IPCs*2/36)= 4/6] .67 = 1 IPC/ run 39%

Night time bombing played as Convoy disruption on 1-3 damage (4-6= 0), no AA fired:
1+2+3+0+0+0=6/6=                     +1 IPC             - 0 IPC = 1 IPC damage/ run 39%

Just make it a NO for the US that it needs a cumulative die roll to obtain nukes

Certain things have to happen in order for the US to roll “Atomic Dice”

Allied control of Rome
No Axis controlled territories in Africa
The Axis cannot control US originally controlled territories in the Pacific (Guam, Midway, Hawaii, Johnston, Line, Philippines, Aleutian)
The Axis cannot control UK originally controlled territories in Europe (London, Scotland, Iceland, Gibraltar)
Anzac has to have collected IPC that round

Before Germany goes in that round, the US gets to roll a die for each of the following:
US Control of Rome
US Control of Hawaii
US Control of Caroline Islands
US Control of Marianas
US Control of Iwo Jima
US Control of Okinawa
US Control of Marshall Islands
France collected IPC that round
Allied Control of Egypt

You have to roll something like six sixes in order to obtain an atomic bomb.  Thats six sixes cumulatively.  Alternately, you can make it a cumulative total so something like you have to roll something like a die total of 40-50 cumulatively on the die roll(s) over multiple rounds.

Each nuke thereafter costs the US 1/3 of its IPC to purchase it (so probably something like 25-30 IPC at this point in the game).

The Nuke works just like a SBR however it can only be on the Nation’s Capital (Tokyo / Berlin).  If the StratB’s with the Nuke(s) get to the roll dice phase for damage to the Major IC, then the attack is successful.

A successful attack means that nation does not collect IPC that round.

From the German perspective:

Germany rolls a single die every round for the following objectives:

German Control for each VC it controls

So G1 would see Germany likely roll die for Berlin, Warsaw and Paris.

Germany would also be able to roll die if it controls London, Egypt, Leningrad, Stalingrad, and/or Moscow which allows for Germany to go in any direction to obtain extra die rolls.

Germany scores half (rounded down) its total die roll if the Axis does not control Paris and Rome.

Germany has to obtain the same objective as the US to obtain an Atomic Bomb (six sixes or something like 50 total showing on the dice cumulatively through all rolls).

I believe this puts the Atomic Bomb in play for Germany around turn 7-8 if it never loses Paris and owns London.  However Germany could only really play that Atomic bomb against Moscow if it sealioned G3 as its pretty darned difficult for it to launch a SBR against the US.  In effect it penalizes Moscow for sitting back and really doing nothing instead of pushing back against the Germans.

I like it. Simple and effective.
