Aerial Fire Support

Use this Stratagem in the enemy Charge phase
after a TEMPESTUS DROP FORCE
INFANTRY unit from your army is chosen as
the target of an enemy unit's charge. Pick a
TEMPESTUS DROP FROCE 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.
