A charge can sometimes trigger extra movement from the enemy. For example, Goblin Fanatics will leap out of their units as soon as enemy approach within 8'. This happens out of the normal sequence: the charge is halted as soon as the chargers move within 8" and the Goblin Fanatics are moved and any damage they cause is worked out straight away. It is up to the player to say that he has out of sequence movements or actions to perform at the appropriate moment.
