Rules (5) Master of the Hunt If Kor'sarro Khan is your Warlord, friendly White Scars models that have the Bike unit type, or are embarked on a Rhino or Razorback, have the Scout special rule. In addition, if Kor'sarro Khan slays the enemy Warlord in a challenge, you immediately score D3 extra Victory Points And They Shall Know No Fear A unit that contains at least one model with this special rule automatically passes Fear and Regroup tests. When it Regroups, the unit does not make the 3" Regroup move, but can instead move, shoot (or Run) and declare charges normally in that turn. Furthermore, if a unit containing one or more models with this special rule is caught by a Sweeping Advance, they are not destroyed, but remain locked in combat instead. Furious Charge In a turn in which a model with this special rule charges into combat, it adds +1 to its Strength characteristic until the end of the Assault phase. A model that has made a disordered charge that turn receives no benefit from Furious Charge. Independent Character Independent characters can join other units. They cannot, however, join units that contain vehicles or Monstrous Creatures. They can join other Independent Characters, though, to form a powerful multi-character unit! Independent Characters pass Look Out, Sir rolls on a 2+. A unit that contains one or more Independent Characters does not need a double 1 to Regroup if reduced to below 25% of its starting numbres, but instead tests as if it had at least 25% remaining.
Full details in BRB. Rule too long to copy verbatim. Chapter Tactics When choosing an army, all models in the same Detachment or Formation must be drawn from the same Chapter. If a unit's datasheet contains a Chapter in brackets after the Chapter Tactics special rule - for example, "Chapter Tactics (Ultramarines)" - the unit must always be drawn from this Chapter, and therefore cannot be included in a Detachment or Formation with any units that are drawn from other Chapters. All models drawn from a given Chapter benefit from that Chapter's Special Rule. If a unit contains models drawn from two different Chapters, it counts as from neither Chapter, and thus benefits from neither Chapter Tactic.
