Abstract: With the rapid advancement of the new global military revolution, the character of future warfare is undergoing profound transformations. The conflict in Ukraine has demonstrated that traditional tiered evacuation and treatment models are increasingly inadequate for meeting the demands of mass casualty care on future battlefields. There is an urgent need to establish a damage control medicine (DCM) technical system characterized by rapid response, precise intervention, and effective life-saving measures. Focusing on the treatment of lethal combat injuries, DCM adopts the core philosophy of "damage control—resuscitation priority—staged repair" to interrupt the "lethal triad" (or "death quartet"). This paper centers on the generative logic and core essence of the DCM technical system, systematically analyzing its necessity and technological underpinnings within the context of modern warfare. DCM represents not merely an extension of surgical techniques but a product of multidisciplinary integration. Looking ahead, DCM will leverage technologies such as big data, artificial intelligence, and telemedicine to construct an intelligent "human-machine collaborative" treatment system. This evolution will provide robust support for enhancing survival rates among wounded personnel and ensuring operational effectiveness.
