5.2 Multiple Attacking Units wrote:
Only units in the same hex can fire simultaneously, and then only at the same target. One unit leads the fire and fires at its full FP. Each additional MMC adds 1/2 of its Firepower to the attack. Heroes add their full Firepower. Zero (0) Firepower units add nothing (unless they are firing a Support Weapon). Machine guns and flamethrowers add their entire Firepower. The total Firepower is summed; remaining fractions are rounded up and the combat is resolved as in the section on Fire Combat.
So, I would say scenario A.
