From the Preface: "The Operational Law Handbook is a 'how to' guide for judge advocates practicing national security law. It provides references and describes tactics and techniques for the practice of national security law. The Handbook is not a substitute for official references. Like national security law itself, the Handbook is a focused collection of diverse legal and practical information. It is not intended to provide 'the school solution' to a particular problem, but to help judge advocates recognize, analyze, and resolve problems they will encounter in the operational context. 'The Handbook is NOT an official representation of U.S. policy regarding the binding application of various sources of law, and should not be used as such.' However, it may reference source documents. [...] Simply put, the Handbook is made for the Soldiers, Marines, Sailors, Airmen, and Coast Guardsmen of the military Judge Advocate Generals' Corps who serve alongside their clients in the national security context. Accordingly, the Operational Law Handbook is compatible with current joint and combined doctrine."
