"Fleets that benefit from a +1 bonus to their Hit and Run attacks roll a 2-7 on a D6, meaning that they will never fail to inflict some critical damage on their target". BFG Basic (Advanced) Rules, pg 35

I've searched in vain and have not found a fleet, race, Assault Boat, Ship, or special troop-type that has this bonus. What am I missing here?

So just who does have a Hit and Run bonus?

Thanks,
