RETURN TO THE SHADOWS

Use in Movement phase, when GSC INFANTRY
unit is selected to move, or in Fight phase, after a
GSC INFANTRY unit has resolved all of its
attacks but before it makes a consolidation move.
If that unit is more than 6" away from any enemy
units, remove from battlefield. In the Reinforcements
step of your next Movement phase, set that unit
back up on the battlefield anywhere that is more
than 9" away from any enemy models. If battle
ends and unit not on battlefield, its destroyed.
