The vehicle can fire one more weapon than
would normally be permitted. In addition, this weapon can
be fired at a different target unit to any other weapons,
subject to the normal rules for shooting. Therefore, a
vehicle that has moved at combat speed can fire two
weapons, and a vehicle that has either moved at cruising
speed, or has suffered a ʻCrew Stunnedʼ or ʻCrew Shakenʼ
result can fire a single weapon.
