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.
Heavy Barrage Weapons with the Heavy Barrage trait follow all the rules for Barrage weapons. In addition, weapons with the Heavy Barrage trait can damage Structures. If targeting a Structure with one or more Detachments Garrisoned inside it, the controlling player makes Hit rolls against the Structure equal to the Dice value of the weapon and makes Hit rolls against 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 resolved against surviving Detachments after it collapses.
