Assault Launchers

Select one AA ASSAULT LAUNCHERS unit from your army and one enemy unit (excluding VEHICLE or MONSTER units) within 9" of that unit. That enemy unit can either brace or duck for cover.
If that unit braces, it suffers D3 mortal wounds.
If that unit ducks for cover, then until the end of the turn, subtract 1 from the Attacks characteristic of models in that unit, and that unit cannot fire Overwatch or Set to Defend.
