Bombing by Average

This house rule was designed by myself independent of any other source and was made in the 1980s when I played A & A Classic and designed my own variant I term ‘Allies and Enemies’. The rule is as follows; During a develop weapons phase a player mat attempt to develop an atomic bomb. A player must pay 30 PFs for every die roll that is attempted. A roll of a 6 on a D6 roll gives the player nuclear capability (needless to say the die roll must be clearly random). Additionally, the second time (a subsequent turn) a player pays 30 PFs to attempt to develop an atomic bomb the die roll to be successful becomes a 5 or 6 on a D6 roll. For each subsequent attempt of 30 PFs the die roll to be successful decreases by one number so that on the sixth attempt research for an atomic bomb is automatically successful. On the turn that an Atomic bomb is successfully developed that player may buy them at the purchase units phase for 5 PFs for each Atomic Bomb. Atomic Bombs may only be delivered to the target space by Bomber aircraft ( 1 atomic bomb per bomber) or by a Rocket (if house rules allow). The effects of an Atomic Bomb are 1) destroys all units in the target space (either land or sea) and 2) permanently (for the rest of the game) reduces the PF value of the land space targeted by 1 PF (0 being the minimum value) for each Atomic bomb dropped.

Here are our Atomic weapons rules
Only Germany and USA may research them.
Must pay 5 IPC to research. Roll one die and on a result of 6 a technological breakthrough has occurred.
Then roll 2 dice to determine the technology discovered. We have multiple technologies for USA and Germany.

12 – Atomic weapons.
Atomic bombs cost 24 IPC to build. Only two may be built per turn. May not be built on same turn as breakthrough turn.

Move as infantry by land or sea. If loaded on a strategic bomber, it can move the current range of the bomber

Due to a lack of trained technicians and engineers, a nation may possess no more than 2 weapons at one time.
Due to the size and nature of the airburst associated with the nuclear warhead, no attack roll is required to score a successful hit.
No air defense, such as fighter scramble, is allowed due to the altitude of the strike plane and surprise of the attack. Only upgraded fighters may intercept. Long range aircraft or jet power technology must have been successfully researched to intercept an atomic strike.

An atomic weapon is treated as an AAA gun if the territory in which it is stored is attacked. 
No AAA guns are to be fired due to the altitude of the strike plane and surprise of the attack only normal built in AA gun defenses with an industrial facility can fire. Airbase and naval base do not fire AA.
Any industrial complex is attacked with 4 dice disabled to maximum value of 20 for major and 2 dice disabled to maximum value of 6 for minor complexes.
Any airbases or naval bases in the territory are attacked by one dice of value.
One dice is rolled and that number of units of defenders choice eliminated. AAA guns may be chosen.

If used on a naval assault:
The nuclear strike cannot be combined with surface vessels or additional aircraft.
Due to the altitude of the strike plane and surprise of the strike, aircraft on carriers and loaded troops on transports are considered to be cargo and provide no defense. The 5 hits are assessed and the attacking bomber returns to base. No 2nd attack is permitted.
Transports chosen last.

I will summarize 3 ways of doing G40 SBR with Fgs escort and interceptor which could be use as 3 different historical tactics by the attacker trying to whether reduce the enemy’s air power or the IC production while better protecting StBs.

First, is A) the Close-Escort Mission, which is done as OOB SBR.

Second, is B) the Offensive Counter-Air Mission, which gives Fgs A1 first strike and D1 but an opportunity to roll a second time against bombers in A-to-A dogfight.

Third, is C) the Night Bombing Mission, in which Fgs units cannot participate neither offense nor defense.

A) Close-Escort Mission, as OOB
Air-to-Air phase
All attacking planes (Fg,TcB, StB) inside roll A@1.
All defending Fgs roll D@1.
Remove casualties.

Bombing phase
Proceed to SBR over IC, NB or AB.
AAA fires @1 against StB and TcB
Then roll damage as OOB: StB D6+2, TcB D6.

B) the Offensive Counter-Air Mission, Fgs are actively chasing intercepting Fgs
Air-to-Air phase
First cycle:
All attacking Fgs can roll A@1. Remove casualties.
All other attacking planes (TcBs, StBs) roll A@1.
All defending Fgs roll D@1.
Remove casualties.

Second cycle:
Then, defending Fgs roll D@1 a second time inside the A-to-A phase.
And all hits in this second cycle are allocated first to bombers, if any. Remove casualties.
All surviving attacking Fgs can now roll A@1 in this second cycle. Remove casualties.

Bombing phase
Proceed to SBR over IC, NB or AB.
AAA fires @1 against StB and TcB
Then roll damage as OOB: StB D6+2, TcB D6.

C) the Night Bombing Mission

Night Bombing phase
Proceed directly to SBR over IC, NB or AB.

AAA fires @1/D12 against StB and TcB or
@Baron:

“Historical” light projector “search and spot” in the night sky:
Each StB/TcB is spotted on a 3 or less.

Then roll to A@1 on spotted StB with AA gun: on “1” roll a spotted StB/TcB is destroyed.
(Work as the usual in-built AAA in IC.)

All surviving StBs bombard roll for damage: (1D6+2)/2 rounded down against IC.

All surviving TcBs bombard roll for damage (1D6)/2 rounded down, minimum 1 IPC, against IC.

@Baron:

Trying to depict the two escorting fighters tactics with an additional HR inside the actual G40 OOB SBR escort and interception rules, I come to this:
It would be an attacker’s choice whether he chooses the close-escort mission or an Offensive Counter-Air mission.

Close-escort mission:
When playing as OOB SBR (all @1), it is like Fgs are providing close-escort to bombers.

Offensive Counter-Air mission version A:
Air-to-Air combat phase in SBR with Fgs actively chasing intercepting Fgs :
All attacking Fgs can roll A@1. Remove casualties.
All other planes (TcBs, StBs and defending Fgs) roll A/D @1. Remove casualties.
Then, defending Fgs roll D@1 a second cycle inside the A-to-A phase.
And all hits in this second cycle are allocated to bombers. Remove casualties.

Proceed to SBR over IC, NB or AB.
AAA fires against StB and TcB.
Then roll damage as OOB.

I think it is a way to simulate the two tactics at a Strategical level game.
It can give a better historical feel and variation of attacking SBR strategy, at least on this point, than just the actual OOB.
Attacking Fighters get a preemptive strike, and any hit is also a way of protecting bombers,
while defending Fgs get special treatment on the second cycle: a second chance to make a hit @1 on bombers specifically.

In addition, maybe the comparison can provide us a way to explain why Fgs are not better than bombers and stay A/D @1:

the escorts are restricted in their role, they have limited ability to score hits, however, by staying close to the bombers they make it more likely that they will be taken as a casualty, the losing player gets to decide their losses.

If on the other hand, the escorts are allowed to pursue interceptors, they are more effective at shooting them down, but in that case, they are not as effective at protecting the bombers, therefore, the interceptors get to choose their hits.

On one part, we can say that for escorting Fgs providing cover impaired all of them, moving at a slower pace and keeping an eye on bombers.
On the other part, defending interceptors are also somewhat impaired by the defensive formation of Bombers and Fgs, so they didn’t get any advantage of the “flying over homeland territory” would normally provide against less manoeuvrable target.
So, after all, Fgs get A1D1 while the rest of TcBs and StBs just getting A1 but D0.
(And based upon IPC cost, it is just enough to say a Fg unit is slightly better than the rest.)

In summary, about Offensive Counter-Air mission :
The first cycle is a regular for defending planes, because they have to scramble and can be caught off guard by attacking Fgs. They get the superiority once in the air.

The first cycle of SBR interception phase is as OOB, except for attacking Fgs.
The second cycle is for surviving defending Fgs which get an advantage since there is no close-escort Fgs for Bombers.

In addition, this can provide a distinctive ability toward Fgs vs TcBs.

This HR was only a way to depict in game term this historical tactics, but if there is already a way to rationalize it inside OOB rules, feel free to develop it, so it can add a layer of historical depiction and feeling toward Fighter unit.

EDIT:
Here is another way of depicting this Offensive Counter Air-Mission version B:

What could happened historically?
A typical example from the Battle of Britain:
A flight of Ju88, He111 and Do17 Bombers sent in to bomb British ABs with a group of 109’s in support.
A group of Spitfires and Hurricanes comes up to intercept.
The 109s jump the interceptors.
The interceptors try to blow by the escorts and get at the bombers.

Escorts are flying in ahead of the Bombers and meet the interceptors before the wing of Bombers.

Escorts and Interceptors fight one round.
Escorts and interceptors roll on A/D@1. Remove casualties.
Then, escorting and intercepting Fgs and Bombers all roll on A/D@1. Remove casualties, but Bombers are taken as casualties.
Then, AAA fire, remove casualties.
Proceed to bombing damage.

very true.

As A&A makes no rule for collapsed defenses,  an atomic bomb drop, under any other conditions, against an enemy of any potency, would still suffer teh same flak and interceptor attacks as any other strategic bombing.

@Uncrustable:

I think you should play some games of G40 on here before making these assumptions.
I do, and I see many SBR involving fighters.
Germany sometimes will send 5 or more bombers on Moscow alone, where Moscow has 2-3 fighters to scramble. Odds are better that Russia will lose a fighter before Germany loses a bomber in the air combat. And  Il trade a German bomber for a Russian fighter, Russia can’t afford it.
I also see many games where G2 Germany sends 2 bombers 2-4 tac bombers and 2-4 fighters to London where there are sometimes up to 5 fighters that can scramble.
Italy will also heroically send its lone bomber to London in an attempt to disable the airbase on London before Germany’s turn.

Even with interceptors SBR is a touch too powerful in G40.
This is mainly because bombers are getting +2, meaning 1 bomber auto disables bases and minor facilities once past AA and interceptors.

I would propose taking away bombers +2, while halving tacbombers damage.
Bombers SBR at 1D6
Tacbombers SBR at 1D6 /2. Rounded up.

Now I better see why you wanted to give defending interceptor D2 instead of D1.

Attacker have the advantage of picking which units will go SBR and to concentrate firepower on a single IC.

The defenders are overwhelmed by the sheer number.
In addition, on defense you have often more than just only 1 IC to protect, and you cannot keep all the Fgs in the same territory, have to split them usually.
D2 interceptors can counterweight the advantage of attacker and hindrance of defense a bit.

Reducing attacking bombers to only 1@1  for the whole group is also a way to preserved the defending fighters against destruction by a large number of StBs. But we both know, that is not A&A standard rules, each unit usually get 1 roll…

…unless you treat StBs/TcBs the same way as AAA!!!. :-o
So each defending Fgs can never have more rolled against them than 1A@1, if there is at least the same number of StB/TcBs vs Fgs.

It can be rationalized to get an historical accuracy somehow in the way:
intercepting fighters are not able to attack all groups of StBs/TcBs flying over the territory but only one unit (flight group) at a time.
When interceptors fly around StBs they are under an intense and concentrated AA fire coming from the flying fortress. But all others group of StBs are not chasing actively Interceptors, they are just flying toward the IC/AB/NB target.
So if interceptors are overwhelmed by the StBs/TcBs, it will be in essence 1:1 combat.
1 TcBs A1 vs 1 Fg D2, all other additionnal StBs/TcBs cannot shoot anymore.
In fact, all intercepting Fgs are already busy, other StBs/TcBs have pure and simple an open road toward IC or NB/AB.

What do you think of this one?
When StBs/TcBs attack fighters on SBR air combat, they get A@1 for each StB/TcB or intercepting Fgs wichever is less.

Escorting fighter attack as usual, 1 unit get 1 roll.
Based on 1942.2, I will keep @1 First Strike
Based on G40 rule, if Interceptor has D1, then A1.

(I really wonder why I haven’t think about it, even back in the old thread about StB spam strategy. :?)

I like it, but I think 10 turns is too late, as one side or the other will have achieved a clear victory by that point (even if the game isn’t over). I think mid-to-late game, maybe around turn 7 would be a better time to introduce the bomb. I also think that the bomb should cost 40 IPCs, must be carried in a strategic bomber, and can be shot down. Finally, I think the bomb should do max damage to all facilities, and if used to attack units, it should automatically wipe all of them out. The bombs should only be producible in a major IC.

i like this idea. this idea could work well with using it as a tech such as stategic targeting. or added to heavy bomber tech. this will also could come in handy if HBG starts making light, meduim and heavy bombers

I am gonna post a new version of mine using KISS. I think it is too complicated.

but i will do that in a new thread :-D
