The Unwilling and the Reluctant: Theoretical Perspectives on Disobedience in the Military and The Apathetic and the Defiant: Case Studies of Canadian Mutiny and Disobedience, 1812-1919 are the first two volumes in a series devoted to disobedience issues in the Canadian military. Now with The Insubordinate and the Noncompliant, the trilogy is complete. Military leadership has both formal and informal dimensions. The formal leadership of any organization must ensure that it minimizes the divergence between institutional aims and the actions of informal leaders. When this separation occurs, the result is sometimes mutiny. These incidents of insubordination and noncompliance represent a form of dialogue between military personnel and their leadership. The Insubordinate and the Noncompliant offers a perspective on the Canadian experience with military mutiny in the twentieth century in an effort to provide relevant lessons for today.
