Formation: Bladewing Assault Brotherhood

Once per game, in your Movement phase, you can declare that this Formation will disengage.  Each unit from this Formation that is on the battlefield is removed from play, even if it is locked in close combat, and placed into Ongoing Reserve

If any units from this Formation are in Reserve or Ongoing Reserve, they will arrive at the same time - if you need to make Reserve Rolls, make a single roll for all units from this Formation.  When the Formation arrives from Reserve, draw a straight line from a point on any table edge to a point on the opposite table edge.  Each unit from this Formation must attempt to Deep Strike onto a point on this line.  And can re-roll the scatter dice when Deep Striking.
