lf the charged unit has missile weapons and the chargers are more than half their original charge move away, then troops can shoot at the chargers as they advance. For example, a unit of Knights with Move 7 can be shot at if they charge a unit of Archers that is more than 7" away, but cannot be shot at if it charges a unit 7" or less away. Work this out immediately before moving chargers - refer to the Shooting section for rules governing missile weapons.
Treat stand & shoot responses which fail to hit the enemy because chargers are too close, etc, as a hold response instead.
