Shock Ram "A Vehicle with this Special Rule inflicts more damage when it moves thought enemy Units."
When the Model with this Special Rule and the Vehicle Type moves through an enemy Unit, the number of Hits inflicted is increased from D6 to D6+3. Furthermore, if the Reactive Player declares a Death or Glory Reacting with a Vehicle that has this Special Rule as the target, then the Vehicle with this Special Rule gains a 6+ Invulnerable save against all Hits inflicted as part of that Reaction.
Auto-Repair (X) "A Model with this Special Rule has a bonus to Repair Tests to remove Statuses."
If the Active Player makes a Repair Test in the Statuses Sub-Phase of the End Phase for a Model with the Vehicle Type with this Special Rule, they ignore the usual Target Number of 6. Instead, the value of X attached to the variant of this Special Rule is used as the Target Number for that Repair Test. For example, a Model with the Auto-repair (4+) Special Rule would pass any Repair Tests made for it on the result of a 4 or higher.
