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.
Weapons Array "Weapons with this Special Rule may make Shooting Attacks into multiple Firing Arcs."
When making a Shooting Attack with a Weapon that has this Special Rule, the Weapon may be used to attack once into all four Firing Arcs (Front, Left, Right and Rear). This does count as making multiple Shooting Attacks, but do not need to be made as Snap Shots.
