Modern conflicts once again move towards interstate wars that requires extensive logistical capabilities that enables offensive military operations with conventional forces. As force composition and technical systems becomes more complex, logistical flexibility becomes an attribute necessary to supply high tempo campaigns. The study conducts a comparative case study that investigates the logistical flexibility’s effect on logistical vacuum in past operations. The result display that logistical flexibility is an important factor for successfully supplying offensive military operations at the operational level and the mitigation of the logistic vacuum. The study combines and evaluates logistical factors on the macro and micro level to measure the logistical vacuum present and how it occurs in some cases and is avoided in others. The work contributes to the knowledge of logistical flexibility and how it could affect future force structure and appearance of logistics.
