The rule book states each additional attacking units firepower is half, rounded up. The player aid card states the sum of the inherent firepower of each attacking unit is halved.
So if you have two extra units firing with an inherent firepower of three is the additional firepower three, six halved, or is it four, three halved to one and a half rounded up to two done twice for two additional units?
Should be +3. You add the actual halves and then round up at the end.
