This document discusses the need for the US Army to develop capabilities for operating in the "human domain" as it did previously for the air, land, maritime, space, and cyber domains. It draws parallels between the development of AirLand Battle doctrine in the 1980s in response to the Soviet military threat and the current need to develop new strategies, organizations, training, and equipment for dealing with irregular and hybrid enemies. The document argues that success in modern "wars among the people" requires understanding and influencing populations, so the Army must develop human domain competencies alongside traditional land warfare skills. It also stresses the importance of building global partnerships and networks of allied forces to help address security challenges in a time of fiscal constraints.
