Sharpshooter's long-las

While an operative has a Conceal order, it can perform Shoot actions if this is the ranged weapon (or weapon profile) that is selected for the shooting attack(s).

Each time a friendly operative makes a shooting attack with this weapon, in the Roll Attack Dice step of that shooting attack, for each critical hit retained, inflict x mortal wounds on the target. x is the number after the weapon's MW, e.g. MW3.
