Rules (7) Master of Battle All units with Chapter Tactics (Red Scorpions) in the same detachment as Carab Culln may use his Leadership value for determining the effects of all Pinning tests and Morale checks. Against All Odds Commander Culln and any squad he joins may re-roll all attacks made in close combat when outnumbered in an assault. Whilst alive he also grants himself and his squad the Counter-attack and Stubborn special rules. 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. 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. 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. Counter-attack If a unit contains at least one model with this special rule, and that unit is charged, every model with the Counter-attack special rule in the unit gets +1 Attack until the end of the phase.
If, when charged, the unit was already locked in combat, the Counter-attack special rule has no effect. Stubborn When a unit that contains at least one model with this special rule takes Morale checks or Pinning tests, they ignore any negative Leadership modifiers. If a unit is both Fearless and Stubborn, it uses the rules for Fearless instead.
