ENCIRCLE THE PREY

Use this Stratagem at the end of your turn. Select
one BURROWERS unit or unit that can FLY
from your army. Remove that unit from the
battlefield. In the Reinforcements step of your
next Movement phase, you can set that unit back
up anywhere on the battlefield anywhere that is
more than 9" away from any enemy models.
If the battle ends and that unit is not on the
battlefield, it is destroyed. A unit cannot be
selected for this Stratagem if it was set up on
the battlefield this turn.
