SHOCK AND AWE

Use this Stratagem in your Shooting phase, when
an ADEPTUS ASTARTES SHOCK GRENADES
or 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 attack's
hit roll.
