hi,
since i started this one in the german forum and black legion transferred it to taccom i comment here as well.
i think it's much more easy just to refer to small arms and assault weapons category.
for game mechanisms (and per rules).
assault weapons generate the units cc value. small arms generate the units ff value exclusively.
Quote:
Assault weapons. The effect of these weapons is included in a unit’s Close Combat value and so they can only be used during an assault. For example, Assault Marines with chainswords have the effect of these weapons included in their Close Combat value of 3+.
The term ‘small arms’ covers a dizzying array of short-range weapons used by units in the 41st Millennium. Examples include lasguns, bolters and Ork shootas. The effect of these weapons is included in a unit’s Firefight value and can only be used during an assault. For example, Tactical Marines with boltguns have the effect of these weapons included in their Firefight value of 4+.
this means:
a skimmer may force an enemy in b2b to use its ff value. if this is the case and the ff value is used it relates exclusively to small arms (and the corresponding ff value). no assault weapons may be used since they would relate to the cc value.
the powerfist is an assault weapon.
summary from the german forum and my two cents.
thanks
