There is growing evidence that simultaneous to the Revolution in Military Affairs (RMA), a less obvious, but equally profound, Revolution in Military Logistics (RML) has occurred that shapes and underpins western military effectiveness. However, there has been no conceptualisation of this RML nor its wider effect on Western force structures. This article addresses this gap in the security literature. Using an interdisciplinary literature review and case studies, it makes two central contributions: first, it details how western military logistics systems and practises have transformed following post-Fordist principles in the last two decades. In doing so, second, it contributes a major new conceptual framework to the military logistics and security studies literature. Finally, the implications of these processes for military effectiveness are examined, with the conclusion asserting that the cumulative effect of this post-Fordist RML has potentially increased western militaries’ strategic vulnerability.
