Concussive Firepower effect when a Tank is Heavily Damaged question?

By player338749, in Tide of Iron

When any heavily damaged tank performs a regular concentrated fire attack by itself against a squad defending in a building is the concussive firepower bonus of the tank also halved? or not? Ex. If a heavily damaged Sherman fires against an infantry squad in a building would its final firepower value equal 5 (6+3=9, halved = "5")? or, would its final firepower value equal 6 (6 halved = 3, +3 = "6")?

You always add any bonuses and then half the firepower. Page 35 of the rule book, calculating modifiers tells you how to go about it.

That answers the question.
