The intention of this paper is to examine two broad themes which are relevant to military doctrine in general as a cohesive body of military thinking. The first will explore the problem of defining 'military doctrine' and its purpose. Having a common understanding of what is meant by 'military doctrine' is something of fundamental importance if doctrine is to have any utility to its users. The second will consider the inherent tensions in doctrine when trying to formulate it, disseminate it or apply it. How these inherent tensions or 'contradictions' are resolved shapes the efficacy of the military doctrine and reflects the character of its users.

Introduction -- Defining doctrine -- Inherent tensions in doctrine -- Initiative or conformity? -- Utility at all levels of war? -- Flexibility -- Past, present or future? -- Conclusions.
