AUSPEX SCAN

Use this Stratagem at the end of the Reinforcement
step of your opponent's Movement phase. Select
one ADEPTUS ASTARTES INFANTRY unit
from your army that is not within Engagement
Range of any enemy units. That unit can shoot as
if it were your Shooting phase, but its models can
only target a single eligible enemy unit that was
set up as Reinforcements this turn and that is
within 12" of their unit when doing so.
