A battery whose morale is shaken or worse may not fire. Damaged batteries are silenced if they also have any morale hits. Artillery may not fire through or over friendly units, including skirmishers. All standard artillery fire conducted during the Artillery Phase is considered simultaneous. Batteries which suffer damage within the same phase will not have their damage effects applied until it's end.
Prolonged artillery is excepted.
The battery may not fire that phase and must remain completely stationary. Place a saved fire marker with the battery to represent the prepared status of the battery. The next time that the battery fires, the fire points expended are doubled, and the saved fire status is lost. Each artillery battery may only accumulate a maximum of one saved fire marker at any one time. Saved fire markers may not be stockpiled or traded among batteries.
