The weapon enables its wielder to fire several shots at a time, rather than a single shot. The number of shots the weapon can fire is stated in brackets. Such weapons can either fire once without penalty, or as many times as indicated in the bracket with a -1 To Hit penalty (in addition to any other modifiers To Hit). War Machines with this rule do not suffer -1 To Hit for firing Multiple Shots.
All models in the unit (excluding characters) must fire either single or Multiple Shots.
