The world is in a period of intense geopolitical competition, with the potential for conflict looming large. As potential adversaries field ever more powerful weapons systems designed to keep US forces at bay, the US military must find new ways to project power and defend our interests. This manual, the *Tentative Manual for Expeditionary Advanced Base Operations* (TM EABO), outlines a bold new concept for employing naval expeditionary forces, operating in a highly distributed, mobile, and low-signature manner to "stand in" and deny adversaries control of key maritime terrain. This second edition builds upon previous work, drawing on lessons learned from war games, exercises, and experiments to provide a comprehensive description of how naval forces will conduct EABO across the competition continuum. The document is a must-read for anyone interested in the future of naval warfare. It explores important topics such as: - The operational context of EABO - The planning and organizational considerations involved in conducting EABO - The critical role of intelligence in supporting EABO - The importance of information activities in creating and exploiting information advantages - The unique challenges and considerations of aviation operations in support of EABO - The essential role of logistics in sustaining EABO forces - The concept of operations for conducting littoral operations This manual is not just a theoretical exercise, but a practical guide for those seeking to understand and implement the EABO concept. It provides valuable insights into the future of naval operations and offers a roadmap for how the US military can effectively adapt to the changing security environment. This annotated edition illustrates the capabilities of the AI Lab for Book-Lovers to add context and ease-of-use to manuscripts.
