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.
Barrage When firing a weapon with the Barrage trait, a model may target Detachments that it does not have line of sight to, as long as the target Detachment is in range and meets all other criteria for a valid target. Models firing against targets they cannot draw line of sight to suffer a -1 penalty to all Hit rolls.
Hits caused a Barrage weapon fired in this way can be allocated to any model in the target Detachment that is within range of the firing model. If some models from a Detachment are visible and some are not, the controlling player can choose to only target the visible models - if they do so, they do not suffer a -1 penalty but any Hits scored cannot be allocated to models outside of the firing model's line of sight.
If a Barrage weapon targets a Detachment that is Garrisoned within a Structure then all Detachments Garrisoned within it are targeted. Make Hit rolls against each Detachment Garrisoned within the Structure, equal to half the Dice value of the weapon (rounded up) - this reduction in Dice happens even if only one Detachment is Garrisoned within.
Barrage weapons cannot be fired as part of an Overwatch.
