Automated Sentry Detachments with this special rule are ignored for the purposes of calculating a Formation's Break Point.
Automated Sentry Detachments are not issued with an Order. Instead, when a Detachment with the Automated Sentry special rule is activated during the Movement phase it may fire. If there are no viable targets, then it is activated and may fire in the Advancing Fire phase of the Combat phase instead.
When firing with a model with the Automated Sentry special rule, the controlling player does not choose targets in the normal manner. Instead, it fires any weapons with the Anti-tank trait at the closest eligible enemy Detachment containing Walkers, Vehicles, Super-heavy Vehicles, Knights or Titans and any weapon with the Light trait at the closest eligible enemy Infantry or Cavalry Detachment. If a weapon has the Skyfire trait, the controlling player may choose to target the nearest Detachment with the Flyer special rule instead.
An Automated Sentry model fires any other weapon at the closest eligible enemy Detachment.
Automated Sentry Detachments can fire when Engaged & Pinned. When selecting targets, they ignore any Detachment which is Engaged & Pinned, including any Detachment they are Engaged & Pinned with.
