Sepulchral Stalkers

Instead of setting up a unit of Sepulchral Stalkers on the battlefield, you can place them to one side and say that they are set up beneath the ground. In any of your movement phases, you can set the unit up on the battlefield more than 9" from any enemy models. This is the unit’s move for that movement phase. The Sepulchral Stalkers can burrow back underground in any of your future movement phases. If they do, remove the unit from the battlefield – it can return in a later turn as described above.
