Cache of Demolition Charges

In the Shooting phase, one model embarked upon a vehicle equipped with Demolition Charges can choose to throw one instead of firing its normal weapon. However, each time a vehicle equipped with Demolition Charges suffers a penetrating hit, roll a dice. On the roll of a 1, the vehicle suffers a further Strength 8 AP2 hit after any initial damage has been resolved. Note: vehicles equipped with this upgrade ignore the 'one shot' rule on the weapon.
