Melta (X) "This Special Rule increases the amount of Damage against Vehicles when Shooting Attacks are made withing a specific range."
If at least one Model in a Unit with the Vehicle Type that is targeted by a Shooting Attack made by a Model using a Weapon with this Special Rule is within a range equal to or less than the value specified by X, that attack has the Armourbane Special Rule and the Damage of Penetrating Hits caused by that attack is doubled.
Heavy (X) "Weapons with the Heavy (X) Special Rule gain +1 to a Characteristic when Stationary."
When making a Shooting Attack with a Weapon that has the Heavy (X) Special Rule, a modifier of +1 is added to a Characteristic if the Model with that Weapon is part of a Unit that remained Stationary in the Controlling Player’s previous Movement Phase. If the Characteristic listed is AP, then instead it improves the AP by one Step. The value of X in the specific variant of the Heavy (X) Special Rule determines which Characteristic gains the +1 modifier.
