For me, a “light bomber” would a fighter equipped as a dive bomber/fighter bomber. For this, I use the “Luftwaffe Dive Bomber” NA (both standard and Larry Harris Tournament Rules) and simply make it standard. When enemy fighters aren’t present, a fighter may act as a dive bomber. It attacks on a 5 in 1st round, or can strategic bomb for half a dice value.
Med bomb OOB
Heavy Bomber 4-2-6-15
I don’t agree that a bigger plane would…or maybe it would have better range? Okay, say a HB has a base range of 8, does long range make it 10? That’s too much for me. That’s like a Cold War Age nuclear bomber.
Anyway, hits on best out of 2 dice, strategic bombing damage is highest dice +1.
