Fire Overwatch

TARGET: One (non-TITANIC) eligible to shoot
unit from your army that is within 24" of that
enemy unit.
If that enemy unit is visible to your unit, your
unit can shoot that enemy unit as if it were
your Shooting phase. Each time a model in your
unit makes a ranged attack, an unmodified Hit
roll of 6 is required to score a hit.
You can only use this Stratagem once per turn.
