Warhammer 40k how do you work out tank damage?

Answer 1

Simple: Str+d6 vs AV After rolling against your ballistic skill and hitting the tank, take the strength of the weapon being fired at the tank and add the result of a single dice roll (sometimes a weapon will allow you to roll additional dice) to the strength of the weapon. Compare this number to the armor value of the tank facing the model that fired the weapon. If the damage roll (as described above) is less than the armor value of the tank, the shot has no effect. If the damage roll is equal to the armor value of the tank, you score a glancing hit. Roll a single dice (d6) and refer to the Vehicle Damage Table in the reference section of the Warhammer 40k rule book, and subtract 2 from the dice roll (to a minimum of 1). Apply that result to the tank. If the damage roll is more than the armor value of the tank, simply roll a d6 and refer to the Vehicle Damage Table and apply the result of the dice roll to the vehicle (no subtraction). Note that special rules (such as skimmers moving fast, cover, or smoke launchers) may alter these results.
