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.
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.
