SUPPRESSION FIRE

Use this Stratagem in your Shooting phase,
when a WHIRLWIND model from your
army is selected to shoot. Until the end of the
phase, each time that model makes an attack
with a weapon that has the Blast ability, if a
hit is scored for that attack, then until the start
of your next turn the target cannot fire Over-
watch or Set to Defend, and cannot be selected
to fight until all eligible units from your army
have done so.
