The Security Nexus paper examines how civilian and support personnel within the U.S. Department of Defense (DOD) can contribute to Secretary of Defense Peter Hegseth’s renewed emphasis on military lethality. The paper highlights the critical role of non-warfighters—including resource managers, logisticians, academics, economists, and cybersecurity professionals—in optimizing processes, streamlining decision-making, and supporting operational forces. It emphasizes that lethality is not solely about combat but also about strategy, logistics, innovation, and partnerships.
