MASSED FIREARMS

Use this Stratagem in your Shooting phase,
when a GENESTEALER CULTS CROSSFIRE
unit from your army that contains 6 or more
models is selected to shoot. Until the end of the
phase, each time a model in that unit makes a
ranged attack, if all the models in that unit target
one enemy unit that has a crossfire marker,
an unmodified hit roll of 6 automatically wounds
the target.
