Ripper Swarms

During deployment, you can set up a unit of Ripper Swarms underground instead of on the battlefield. At the end of any of your Movement phases, they can tunnel up to the battlefield - set them up anywhere that is more than 9" from any enemy models.

Unless a unit with this ability is within 24" of any friendly Synapse unit, you must subtract 1 from any hit rolls made for it when shooting any target other than the nearest visible enemy unit, and you must subtract 2 from its charge roll if it declares a charge against any unit other than the nearest enemy unit.
