Designated Quarry

At the start of the battle, once both armies have set up all their models, including any units with the Infiltrator special rule, a single enemy unit with the Gargantuan, Super-heavy, Knight or Titan Unit Sub-type may be chosen by the player that controls any models with this special rule - this enemy unit is considered the 'Designated Quarry'. When any friendly models with this special rule are used to make a Shooting Attack against the enemy unit their controlling player has selected as the Designated Quarry, all failed To Wound rolls of '1' may be re-rolled. If the enemy unit selected as the Designated Quarry has an Armour Value, add +1 to any results rolled on the Vehicle Damage chart as a result of Shooting Attacks made by models with this special rule.
