"Within the NWL [Navy Warfare Library], doctrine refers to overarching guidance that allows collections of Navy units to operate effectively as a Navy force. Doctrine therefore refers to both fundamental principles and operational-level guidance. This operational-level doctrine is distinct from the tactics, techniques, and procedures (TTP) used to guide the specific operation of platforms and systems. Doctrine is issued in top-level JPs, NDPs, and NWPs. Navy doctrine forms a bridge between the naval component of our nation's military strategy and ur TTP. A commander, however, cannot operate solely under the guidance of broad strategy. Neither can the commander make appropriate mission decisions if guided only by TTP. Doctrine guides our actions toward well-defined goals and provides the basis for mutual understanding within and among the Services and the national policymakers. It ensures our familiarity and efficiency in the execution of procedures and tactics". (Navy, Navy Warfare Library, 2005, 1-1)
