Aggressive Adaptation

Use this Stratagem in the Fight phase, when
an enemy unit is destroyed as a result of an attack made by a model from your army. Until the end of the battle,
improve the Armour Penetration characteristic of melee weapons that models
in that model’s unit are equipped with by 1
(e.g. AP 0 becomes AP -1). Each unit can only be affected by this Stratagem once per battle.
