Irregulars "A Unit composed of Models with this Special Rule can still score Objectives when Pinned, Stunned or
Suppressed, and is automatically destroyed when it Falls Back into contact with a Battlefield Edge."
A Unit which is entirely composed of Models with this Special Rule (but not the Cavalry Type) is still eligible to
Control or Contest an Objective Marker if it is affected by the Pinned, Stunned or Suppressed Tactical Status (in any combination), but only scores 1 Victory Point for that Objective Marker when affected by these Statuses, regardless of its value and any other Special Rules such as Line (X). While affected by any Tactical Status, Models in this Unit do not add the value of any variant of the Line (X) Special Rule they may have to their Tactical Strength when deciding if they can contest an Objective.
Additionally, when a Model from a Unit containing any Models with this Special Rule moves into Base Contact with any point on the Battlefield Edge as part of a Fall Back Move, all Models in that Unit are automatically removed as Casualties.
