Shock and Awe

Use this Stratagem in your Shooting phase,
when an LAND SPEEDER STORM unit from
your army is selected to shoot. Select one enemy
unit within 6" of that unit. Until the start of
your next turn:
- The selected unit cannot fire Overwatch or Set
to Defend
- Each time a model in the selected unit makes
an attack, subtract 1 from that attacks' hit roll.
