Here´s another one: If attacking an adjacent hex with a flamethrower squad, this squad gains +2 firepower. In an assault attack, the assaulting unit gains +2 firepower if it has flamethrower specialisation. Does this mean you gain +4 firepower, if you perform an assault with a flamethrower unit (+2 because it attacks from an adjancent hex and + another 2 because it is an assault)?

Just +2. The assault rules basicaly have their own calculation method.

Agreed, that's the way we play it.
