Military medicine in transparent large-scale combat operations: rethinking medical timelines as operational planning variables

Large-scale combat operations (LSCO) are increasingly shaped by persistent surveillance, precision strike capability, electronic warfare, contested mobility and repeated attacks on healthcare personnel and facilities. These conditions challenge a core assumption of military medical planning: that casualties can be moved rapidly and predictably through a linear evacuation chain. This article asks how commanders and medical planners should treat medical timelines when evacuation, protection, logistics and information are themselves contested. Drawing on a directed qualitative content analysis of doctrinal, empirical, institutional and clinical sources, it identifies three linked mechanisms: evacuation becomes a contested operational activity rather than a predictable transport function; clinical responsibility shifts forward across an extended continuum of care and survivability depends on interdependence among mobility, protection, logistics, command-and-control, information and clinical capability. The implication is not that rapid evacuation has become obsolete, but that fixed evacuation timelines are brittle planning assumptions in transparent LSCO—a battlespace in which persistent, multi-domain surveillance makes concealment, massing and uncontested evacuation difficult. Military medicine should therefore be planned as a coupled operational capability that shapes course of action development, command risk assessment, wargaming and force generation. The policy challenge is to design medical systems that preserve combat power when movement, visibility, capacity and information are contested.
