Gauss When firing a weapon with this special rule, a To Wound roll of a 6 wounds automatically, regardless of the target's Toughness. Against vehicles and buildings, an Armour Penetration roll of a 6 that does not cause a penetrating hit automatically causes a glancing hit.
Skyfire A model with this special rule, or that is firing a weapon with this special rule, fires using its normal Ballistic Skill when shooting at Flyers, Flying Monstrous Creatures and Skimmers, but it can only fire Snap Shots against other targets.
Interceptor At the end of the enemy Movement phase, a weapon with the Interceptor special rule can be fired at any one unit that has arrived from Reserve within its range and line of sight. If this rule is used, the weapon cannot be fired in the next turn, but the firing model can shoot a different weapon if it has one.
