Infoslave Skull

Use this Stratagem immediately after your
opponent sets up a unit that is arriving on
the battlefield as reinforcements within 12"
of one of your Ad Mech INFANTRY units.
Your unit can immediately shoot at that enemy
unit as if it were the Shooting phase, but you
must subtract 1 from all the resulting hit rolls.
Mono-task infoslave skulls make ideal lookouts
to watch against the sudden deployment of enemy
troops.
