Tank Shock

WHEN: Your Charge phase.
TARGET: One VEHICLE unit from your army.
EFFECT: Until the end of the phase, after your
unit ends a Charge move, select one enemy unit
within Engagement Range of it, then select one
melee weapon your unit is equipped with. Roll a
number of D6 equal to that weapon's Str.
If that Str characteristic is greater than that enemy
unit's Toughness characteristic, roll two
additional D6. For each 5+, that enemy unit
suffers 1 mortal wound (max of 6 mortal wounds).
