@toblerone77:
I’m just going to say something here. Excluding your math Baron. The whole point of this rule was to open up a way for SBR against ICs with a loose historical basis. The loose historical depiction of night bombing was to give the attacker a less risky SBR but the penalty was less risk=less reward.
Given the basic concept, I think it is viable. I liked the idea of night fighters but thought it best to drop them. That’s my POV. An SBR that drops interceptors/escort could simulate this simply.
Personally I like the thought of using a combination of D6 and D12 dice. When using a D12 system D6 dice aren’t necessary. I know this but I like D6 dice and will continue to use them. I also intend to use D12 dice for custom units and rules in the future and also have other ideas in the works.
I encourage everyone to post as they like. Personally I like the idea of simply eliminating escorts and interceptors for night raids and reducing AA fire 1@D12. Damage totals are halved. That’s just what I like.
Everyone else, carry on.
About damage halved, you will use (1D6+2)/2 rounded up?
D3+1 (avg 3) * 11/12 = 33 IPCs/12 = 2.750 IPCs/ StB - 1 IPC = 1.75 IPCs/ run 68%
So, TacB damage (if allowed) will be D6/2, since regular is D6 ?
D3 (avg 2) * 11/12 = 22 IPCs/12 = 1.833 IPCs/ StB - 1 IPC = 0.833 IPCs/ run 32%
Ultimately, at a strength of 68% of OOB for StB Night-Bombing, this will be very attractive tactics I think.
Much more than using regular AAA@1 and 1D6 damage (only 35.5% of OOB SBR).
It will be almost two times more effective than using 1942.2 SBR as Night-bombing.
And keeping a real half-casualties rate is much clearly depicting the protective effect of Night-bombing than 1942.2 SBR.
Maybe it is still too much and can render OOB SBR obsolete unless attacker want to destroy some enemy’s Fighters.
The base of comparison: was an average of 2.583 IPC/run is a rare situation when the defender have no Fg interceptor to give a better cover for his IC.
A more usual and average situation is probably 1 StB doing SBR against 1 Fg interceptor.
Or any 1 StB : 1 Fg ratio.
(Because if either side can bring too much Fgs, there will be no SBR or no interception.
For example, 1 StB:2 Fgs ratio begins to be unappealing for the attacker:
Damage: + 4.85 casualties: - 5.056 = - 0.206 IPCs damage/StB run)
And it gives these results:
Damage: + 5.487 IPCs/StB
Casualties: - 3.672 =
+ 1.815 IPCs damage/StB run when 1:1
1:1 intercepted SBR, 1.815 vs Night bombing (d3+1), avg 3 for 1.75 IPCs/StB run gives 96%, almost even!!!.
1.815 vs (D6+2)/2, avg 2.75, for 1.521 IPCs/StB run, gives 84%
1.815 vs (d6-1), avg 2.5, for 1.292 IPCs/StB run, gives 71%.
1.815 vs (d3), avg 2, for 0.833 IPC/StB run, gives 46%.
1.815 vs (1942.2 SBR AAA@1/6, D6), avg 3.5, for 0.917 IPC/StB run, gives 51%.
I really think this other aspect should be considered since
Night SBR has no interception and provides a way to always overcome any number of Fgs put to protect an IC.
If the damage rate is too much, some players will find this frustrating being crippled by a fleet of Night StBs.
In addition, historically speaking, Night Bombing was less dangerous but also clearly less accurate than day-time.
(It seems that some Day light raids have 5% vs 1% casualty for Night, 5 times less, but 1 Night bomber out of 3 was finding target in the worst situation, like foggy night…)
So, what is the balance damage rate for an interesting but not too appealing either Night SBR?
Here the calculations:
OOB G1940: 1 StB A1 vs 1 Fg D1 doing interception
StB roll /Fg roll / AAA roll
116= 6/216 1 StB killed by Fg vs 1 Fg killed: 2.8%
151= 5/216 1 StB killed by AAA vs 1 Fg killed: 2.3%
155= 25/216 no casualty vs 1 Fg killed: 11.6%
516= 30/216 StB killed by Fg: 13.9%
551= 25/216 StB killed by AAA: 11.6%
555= 125/216 both survived: 57.8%
Results:
69.4% * ((1+2) +(6+2) IPCs)/2= + 5.5 IPCs) = 3.817 IPCs
16.7% killing Fg *+10 IPCs = + 1.67 IPC
30.6% StB killed *-12 IPCs = - 3.672 IPCs
Sum: 5.487 - 3.672 = + 1.815 IPCs damage/StB run
OOB G1940: 1 StB A1 doing SBR against 2 intercepting Fgs D1
StB roll / interceptors Fgs roll / AAA roll = odds casualties
1/611/366/6= 66/1296 1 StB killed by Fgs vs 1 Fg : 5.09%
1/625/361/6 = 25/1296 1 StB killed by AAA vs 1 Fg : 1.93%
1/625/365/6 = 125/1296 no casualty vs 1 Fg : 9.65%
5/611/366/6 = 330/1296 1 StB killed by Fgs vs no casualty : 25.46%
5/625/361/6 = 125/1296 1 StB killed by AAA vs no casualty : 9.65%
5/625/365/6 = 625/1296 no casualty at all : 48.22%
Results:
Bombard on IC: 57.87% * ((1+2) +(6+2) IPCs)/2= +5.5 IPCs) = 3.183 IPCs
Killing 1 Fg: 16.67% *+10 IPCs = + 1.667 IPCs
StB killed: 42.13%*-12 IPCs = - 5.056 IPCs
Sum: 4.85 - 5.056 = - 0.206 IPCs damage/StB run
