I'm not sure exactly how this works after going over the rules a few times...

Is the firepower of an infantry unit affected by the number of figures on the base or not? I'm not sure if one is supposed to add the firepower rating of each unit together or if it is just a flat 1 regardless of the strength of the unit remaining (such as a flat 1 for regular infantry). Can someone shed some light on how the firepower of an infantry attack should be determined? Thanks.

Infantry firepower is the sum of each models firepower. 1 infantry is one FP, 2 infantry is two, and so forth.

Thanks - I finally found it in the rulebook too
