For years of military operations in Iraq and Afghanistan, US Army forces, along with their joint and coalition counterparts, benefits from a logistics enterprise that ensured every supply need was met. That enterprise—extending from installations at home, through sea and air lines, and all the way to small units in contact—operated largely without disruption by enemy forces. A major war with a peer adversary, however, will present a very different scenario, in which logistics activities will be contested across the strategic, operational, and tactical levels of war. To discuss the challenges that will entail and explore what can be done now to improve the resilience and reliability of US and allied logistics systems, John Amble is joined on this episode by Ron Ti. A retired Australian Army officer with extensive practical experience, he earned a PhD researching combat logistics on the modern battlefield and is the author of a forthcoming book on the subject.
