Warrior Code is a social policy in Civilization V. It is part of the Honor tree. Introducing a Warrior Code in a society causes a profound change in the people's relationship with their military. They see the benefits of a well-disciplined army, complying with strict moral and military laws, and this increases the recruitment volunteering rate in most infantry units. At the same time, military leaders become very popular and tend to arise faster than normal. One of them even appears spontaneously as the people acclaim their new social order!
