Vulcan Mega-bolter

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.

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.

When making Hit rolls for a weapon with the Rapid Fire trait, any natural rolls of a 6 score 2 Hits instead of 1.

Hits caused by a weapon with the Shieldbane trait can be allocated to Void Shields, even if they normally could not be (e.g., because the weapon's AP is 0 or worse).
