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%
