In your game MedBomber 4 @2/12 carpet bombing is a real one each combat round.
Same odds as OOB 4/6, but it is 4 rolls @1. Acting like 4 infantry attacking.
I will try to crunch on this special roll.
4 Infs @1 means 4/6* up to 4 hits for 16 strength points (pipshit) while one regular bomber is
1 roll @4 means 4/6 up to 1 hit for 4 strength.
2 roll @4 means 8/6* up to 2 hits for 16 strength.
So, Med bombers are like twice stronger than OOB G40 StB, assuming same cost.
Because you have more rolls for same odds, you can reduce faster the enemy defending stack for the same attacker sustaining capacity.
To make them even with OOB, in D12, it needs 2 rolls @2/12 for 42 hits = **8 points of strength in D12s pipshit**
Or, mostly, 3 rolls @1/12 for or 3@1/123 hits = **9 points of strength in D12s pipshit**
But you only have 1 hit of sustaining power per bomber…
I think I’m slowly understanding this particular type of dice mechanic.
Comparing both Medium:
A 4d12s @2 ground only every round
A 2d12s @2 naval only every round
and Heavy bomber:
A 3d12s @3 ground only every round
A 2d12s @3 naval only every round
Keepings D12s pipshits
Medium Bomber
4 @2 means 8 pips up to 4 hits for 32 strength points or pips*hit
2 @2 means 4 pips* up to 2 hits for 8 pips*hits
1 @2 means 2 pips* up to 1 hit for 2 pips*hits
Heavy bomber:
3 @3 means 9 pips* up to 3 hits for 27 pips*hits
2 @3 means 6 pips* up to 2 hits for 12 pips*hits
1 @3 means 3 pips* up to 1 hit for 3 pips*hits
This means Medium bomber are more efficient at land units even if less accurate (smaller odds 8/12) than Heavy (9/12) and can be better to lower down enemy stack.
If I compare with YG 3@ 5/8 or 3@3/8.
5/8 means in D12s pips 7.5/12
3/8 means 4.5/12
StBs on land:
3 @7.5 means 22.5 pips* up to 3 hits for 67.5 pips*hits for 1 round only
StBs at sea:
3 @4.5 means 13.5 pips* up to 3 hits for 40.5 pips*hits for 1 round only
