In Multidomain Operations: The Pursuit of Battlefield Dominance in the 21st Century, Amos Fox and Franz-Stefan Gady challenge one of modern war's most influential doctrines: MDO. Is it the right framework for 21st-century conflict-or a concept rushed into service without sufficient grounding? Through the lenses of origin, field application, academic critique, and international perspectives, the authors examine MDO's theoretical and practical shortcomings. They argue that MDO is a solution in search of a problem-strategically narrow, tactically vague, and ill-suited for America's allies. This book calls for a doctrinal reset: one that addresses precision strike overreach, rising attrition warfare, and the enduring need for land forces. With rigorous policy and PME recommendations, Fox and Gady offer a vital roadmap for rethinking military doctrine. Essential reading for defense leaders, scholars, and warfighters alike, this book reshapes how we must think about future battlefields.
