Light AT Hits scored by a weapon with the Light AT trait against a Vehicle, Super-heavy Vehicle, Knight or Titan model treat their AP as 0, regardless of the weapon's base AP value. This can prevent Hits from a weapon with the Light AT trait from being allocated to Void Shields.
Co-axial Some weapons are directly attached to another weapon and will be listed on the Detachment's datasheet as Co-axial. Weapons with this Trait can only target the same Detachment as the weapon it is Co-axial to, even if a special rule allows a model to fire different weapons at different targets.
