Helios Defence Missiles

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.

A weapon with the Skyfire trait can target Flyers as normal instead of requiring a natural 6 to hit. In addition, when a model fires a weapon with the Skyfire trait as part of an Overwatch, subtract 1 from the result of the Hit rolls rather than 2.

Models with at least one weapon with the Skyfire trait may choose to fire on its Detachment's target or a Secondary Target; a Secondary Target is an eligible target (i.e., within range and line of sight of the firing model) different from the first chosen target. The Secondary Target must be a model with the Flyer special rule. All firing Skyfire weapons must target the same Flyer Detachment, unless another rule overrides this.

Hits scored by a weapon with the Anti-tank trait against an Infantry or Cavalry model treat their AP as 0, regardless of the weapon's base AP value.

A model firing a weapon with the Tracking trait at a Flyer can re-roll failed Hit rolls.
