When performing an assault:
1) Do fatigued flamethrower units in barbed wire still contribute the +2FP and -5 cover even though their firepower is zero (from being halved twice)?
2) Do units on op fire contribute their FP to an assault?
Does a unit with a specialization add the FP bonus before or after halving it (if they decided to move and fire, for example)?
" Flamethrower Assaults: For each attacking squad that has the flamethrower specialization, the attack gains +2 firepower. "
The above quote was from page 33 of the rules, which implies, for assaults, at least, that the bonus is added after any halving that might be taking place.
