Aerial Fire Support

Use this Stratagem in the enemy Charge phase
after a TEMPESTUS INFANTRY
unit from your army is chosen as the target of an
enemy unit’s charge. Pick a VALKYRIE
from your army within 6" of the unit being
charged. That VALKYRIE can fire Overwatch
at the charging unit even if it is not the target
of the charge, and when doing so,
will hit the enemy on hit rolls of
4+, regardless of modifiers.
