Say that I am in melee with enemy A. Enemy B is farther away, but within my range. Can I attack B?
The only rules I see are about Ranged Weapons in
Ranged Weapons in Close Combat
No ranged weapon larger than a pistol may be fired at adjacent foes engaged in melee. Larger weapons may be used as clubs, however. Pistols can befired in close combat, but since the defender is actively fighting back, the TN for the Shooting roll is his Parry rather than the standard TN of 4.
However, this doesn't address being in melee and wanting to fire outside of melee. Is this possible?
