card allow the unit to advance if the target is retreated or eliminated?
.No, (page 11 Taking Ground)When an ordered Infantry unit in Close Assault combat eliminates the enemy unit or forces it to retreat, it may Take Ground by advancing into the vacated hex. The key word here is ordered. Only the player taking his turn (ordered units) may take ground during his turn. The ambush card is a reaction play when an opponent declares a Close Assault, and therefore the unit may not take ground even if the opposition is eliminated or retreats.Q.
