Skyfire A model which has this special rule, or that is firing a weapon with this special rule, fires using its normal Ballistic Skill when shooting at Flyers and Skimmers, but it can only fire Snap Shots against other targets.
Sunder Attacks with this special rule may re-roll failed Armour Penetration rolls against Vehicles and Buildings (both with Shooting Attacks and in close combat) and re-roll Glancing Hits, in an attempt to instead get a Penetrating Hit, but the second result must be kept.
One Use/One Shot A weapon or ability with this special rule can only be used once during the course of a battle. Once a weapon with the One Use or One Shot special rule has been used to attack, it is no longer counted as a weapon and may not be destroyed (for example, by rolls on the Vehicle Damage table) or repaired by any other rule or effect.
