'And They Shall Know No Fear'

Space Wolves automatically regroup as they fall back, even if the squad is reduced to less than 50% by casualties. If the enemy advance into them the Space Wolves are not destroyed and the advancement of the enemy unit is treated as a new assault (enemy striking: +1A the following turn) in the same way as a sweeping advance. If the enemy do not advance into them the Space Wolves are free to move, shoot and assault normally in their following turn.
