Suppresive Fire

Use this Stratagem at the start of your Shooting
Phase. Pick an EMPORER'S WRATH
VEHICLE unit from your army. That unit
cannot shoot this phase.
Instead, it lays down suppresive fire; pick an
enemy INFANTRY unit that is within range
of at least one of its weapons. Until the start
of you next turn, that enemy cannot fire
Overwatch and halves its movement characteristic.
