Fleet This special rule is automatically lost by an independent character joining a unit that does not have this special rule, and vice versa.
There are many variants of this rule: Fleet of Foot, Fleet of Claw, even Fleet of Hoof. Title aside, all models with these abilities are treated similarly. In a turn in which models with this rule do not shoot or use a psychic power that replaces shooting, they can move an additional D6" in the Shooting phase, ignoring penalties for difficult terrain.
