POINT-BLANK OVERWATCH

Use this Stratagem when an enemy unit declares
a charge against a unit from your army. Instead
of firing Overwatch as soon as the enemy unit
declares its charge, the enemy unit makes its
charge roll as normal. If this is insufficient to
end a move within 1" of the target, no
Overwatch is fired at the charging unit.
Otherwise, all models in the charging unit are
considered to be within line of sight of all models
in the unit being charged, and within half range
of all of its ranged weapon
