Which manual provides guidance on amphibious warfare doctrine?

The guidance on amphibious warfare doctrine is primarily found in Joint Publication 3-02. This publication serves as a comprehensive guide that integrates various military branches' operations and emphasizes joint planning and execution of amphibious operations. It covers the principles, policies, and techniques necessary for conducting successful amphibious assaults and operations from the sea, ensuring a coherent approach between the Army, Navy, and Marine Corps.

While the Naval Operations Concept and Marine Corps Warfighting Publication provide useful information on broader operational concepts and marine tactics respectively, they do not focus explicitly on amphibious warfare doctrine like Joint Publication 3-02 does. Operational Maneuver from the Sea, while relevant, is a concept that supports amphibious operations but does not replace the comprehensive guidelines found in Joint Publication 3-02. This context reinforces the importance of the Joint Publication as a primary source for amphibious warfare doctrine.
