About the Author Nathan Weiss is a researcher and analyst specializing in urban warfare, defensive geometry, and the structural logic of modern conflict. His work focuses on how cities shape combat outcomes through patterns of depth, mobility, and observation rather than chance or improvisation. Known for his clear, documentary‑style approach, Weiss examines how defensive systems fail under pressure and how those failures influence tactical, operational, and strategic decisions. Urban Geometry and the Marines in Fallujah reflects his commitment to understanding complexity through structure and to bringing clarity to environments defined by uncertainty.
