Undivided - Warp-borne Stalker

During deployment, you can set up this model in the warp instead of setting it up on the battlefield (if this model is a WAR DOG-CLASS model, any other models in its unit are set up as if they were a separate unit). If you do so, then during the Reinforcements step of one of your Movement phases, you can set up this unit anywhere on the battlefield that is more than 9" away from any enemy models.

Once per battle, at the start of your Movement phase, you can remove this model from the battlefield and then, during the Reinforcements step of your next Movement phase, you can set this unit back up on the battlefield, anywhere that is more than 9" away from any enemy models. if the battle ends and this unit is not on the battlefield, it is destroyed.
