An analysis of warfighting trends over a decade could be performed by considering the major crises, conflicts, and tensions that took place, or by tracking the evolving force structure and operating concepts of global competitors. Alternatively, one could compare foundational documents issued over that same timespan. In April of this year, the U.S. Navy, U.S Marine Corps, and U.S. Coast Guard (collectively, the U.S. Naval Service) jointly published the latest version of Naval Doctrine Publication 1: Naval Warfare, superseding the previous version released in 2010. The difference between the two documents is stark, and indicates a change over the last ten years in the way the United States views naval warfare – simultaneously reaching back to its historical roots, while also looking over the horizon to future conflicts.
