Ion Shield

When an Imperial Knight is deployed, and subsequently at the start of each of the opposing side's Shooting phases before any attacks are carried out, the player must declare which facing each Knight's ion shield is covering: front, left, right or rear. The Knight has a 4+ Invul Sv (3+ for Seneschal, 5+ for Knight Apparent) against all hits on that facing until the start of your opponent's next Shooting phase. May not be used against close combat attacks.
