Arae-shrike

If there is a model with an arae-shrike on the battlefield when any enemy player declares a Deep Strike Assault or Flanking Assault, any roll to see if the Deep Strike Assault or Flanking Assault is ‘Disordered’ suffers a penalty of -1 (and is thus counted as Disordered on the roll of a ‘1’ or a ‘2’, unless other modifiers are also applied).
