Vox-skull

Once per battle, at the start of any phase, you can select one enemy unit (excluding Monsters and Vehicles) within 12" of the bearer. That unit must take a Battle-shock test; if that test is failed, until the end of your next turn, that unit cannot have the Benefit of Cover.  Designer’s Note: Place a vox‑skull token next to the unit, removing it once this ability has been used.
