Arc (Front/Rear) A weapon with the Arc (Front/Rear) trait may only target Detachments that are within the specified Arc, shown in brackets, of the firing model.
Bombing Run Weapons with the Bombing Run trait do not as normal. Instead, at any point during a model's move it may pause its movement to attack with any weapons it has that have the Bombing Run trait, following the normal firing sequence. A model firing a weapon with the Bombing Run trait can only target a Detachment or Structure within 3" of it. Each of a model's Bombing Run weapons can only be fired once per round. Models with the Flyer special rule cannot be chosen as targets by a weapon with the Bombing Run trait.
When firing a weapon with the Bombing Run trait, Hits are resolved as normal and can only be allocated against models within 3" of the firing model. If a Bombing Run weapon targets a Detachment that is Garrisoned within a Structure, or targets the Structure itself, then both the Structure and all Detachments within it are targeted. Make Hit rolls against the Structure equal to the Dice value of the weapon and make Hit rolls for each Detachment Garrisoned within the Structure equal to half the Dice value of the weapon (rounded up). Resolve firing against the Structure first. If a Structure is destroyed in this way, firing is resolve against any surviving Detachments after it collapses.
Once the model has resolved firing its weapons with the Bombing Run trait, it continues moving. A model with multiple weapons with the Bombing Run trait may pause its movement as many times as it wishes to in order to fire a weapon with this Trait that it has yet to fire with, so long as it declares all weapons that are firing each time it does so before rolling the dice. A weapon with the Bombing Run trait cannot be fired in the Combat phase - if not fired in the Movement phase, it cannot be fired that round.
A weapon with the Bombing Run trait can damage Structures.
Bunker Buster Hits scored against a Structure by a weapon with the Bunker Buster trait count their AP as double its normal value, e.g., an AP of -3 would become -6.
Weapons with the Bunker Buster trait can damage Structures.
Limited (X) Some weapons can only carry a limited amount of ammunition into battle or are difficult to resupply on the move. A weapon with the Limited trait can only be fired a number of times equal to the number shown in brackets; each time the weapon is fired, decrease that number by 1. When the number reaches 0, the weapon cannot be fired again for the remainder of the battle.
