In a complete game turn, both players get a player turn, each divided into the Movement, Magic, Shooting and Close Combat phases, as shown in the Turn Summary.
One game turn will therefore comprise two player turns, each with its own Movement, Magic, Shooting and Close Combat phases. Whenever a rule refers to a 'turn', whether in this book, a Warhammer army book or an expansion, it means 'player turn', otherwise it will specifically state 'game turn'.
