JDP 0-01 Fourth Edition: British Defence Doctrine

BDD provides the broad philosophy and principles underpinning the employment of the Armed Forces.  It is the basis from which all other subordinate national doctrine describes in more detail how operations are directed, mounted, commanded, executed, sustained and recovered.  This level of military doctrine is, for the most part, enduring.  This fourth edition refreshes the contemporary context and language, and also places additional emphasis on using force or the threat of it for coercion and its subordinate principle of deterrence; an important and fundamental tool of the military craft.  The comprehensive approach is re-titled an integrated approach, as this seeks to encourage collaborative working and co-operative enterprises with other government departments, wider agencies and other actors. 
BDD is divided into 2 parts;

Part 1 – Defence Context.  Chapter 1 explains the relationship between national interests, Defence policy and military strategy.  Chapter 2 expounds the nature of war, the principles and levels of warfare, and its evolving character.

Part 2 – Military Doctrine.  Chapter 3 describes the likely employment of the Armed Forces in pursuit of Defence policy aims and objectives while Chapter 4 explains the components of fighting power and the criticality of the operating context to its effective application.  Finally Chapter 5 describes the British approach to the conduct of military operations.
