Kustom Kombi-Weapon

Nominate a target when the weapon is fired, and roll a D6 and an Artillery dice. Multiply the score on the D6 by 10: the result is the range of the attack in inches.
If the target is in range then it is automatically hit.
The number on the Artillery dice is the Strength of the attack.
Half the Artillery dice roll to determine the save modifier.
Any vehicle hit by the kombi-weapon will take a single hit with an armour penetration equal to the Strength of the attack plus a D6

If you roll a misfire on the Artillery dice, roll a D6:
1-3: Blows up - the mode using the weapon is killed
4-6: Misfire - May not fire this turn but may be used next turn as normal
