While playing your game of Warhammer, you'll occasionally discover exceptions to the general turn sequence laid out above, when things are worked out as they occur rather than in any strict order, or perhaps that both players will have to do something at the same time. Occasionally the actions of one player will trigger the sudden appearance of a particular troop type, or may activate some special rule or occurrence. When this happens, the exceptional rule will contain all the information you need to resolve it.
