[Solved] FIRING A JUST COMMITTED ARTILLERY BATTERY
If the battery is unlimbered during the Artillery & Skirmishing Phase, and it has a valid target, it *will* fire (5.1). The act of unlimbering does not cost any movement (QRG – Movement, 4.2.1). Limbered artillery may not fire (5.1). Unlimbered artillery may not move (3.8.7, 4.2.1).
