CAPTAIN model only. Once per battle, at the start of your Shooting phase, you can select one point on the battlefield and place a marker on that point. At the start of your next Shooting phase, place another marker on the battlefield within 12" of the centre of the first marker, then draw a straight line between the centre of each of these markers. Roll one D6 for each unit that line passes over or through: on a 3+, that unit suffers D3 mortal wounds. Both markers are then removed.
