Ordnance (X) "Weapons with the Ordnance (X) Special Rule double the value of a Characteristic when Stationary"
When making a Shooting Attack with a Weapon that has the Ordnance (X) Special Rule, a modifier of x2 is applied 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 that Characteristic is AP, then the AP is instead changed to AP 2). The value of X in the specific variant of the Ordnance (X) Special Rule determines which Characteristics gains the x2 Modifier.
Armourbane "A Weapon with the Armourbane Special Rule counts Glancing Hits as Penetrating Hits."
When making Armour Penetration tests for an attack with this Special Rule, a result that is equal to, or greater than, the target Armour Value inflicts a Penetrating Hit. A Weapon with this Special Rule can never inflict a Glancing Hit, and any Rule that would force them to do so instead inflicts a Penetrating Hit.
