This essay traces the evolution and use of military scale models during the First World War. The application of such models by all belligerents is characterized by an enormous diversity in scale, context, construction method and purpose. Between the two extremes of a full scale replica of the Paris agglomeration and the tiny boxed miniature of a POW prison cell, a whole range of military models can be distinguished. On one hand, the model production can be considered part of a long tradition of military terrain modeling, as is evident in the examples of relief maps and training models. On the other hand, the rapidly changing technological and tactical developments during the Great War –such as strategic aerial bombing, camouflage and submarine warfare—require the creation of new types of scale models. During the last stages of the war, the encapsulation of the model as research object in a laboratory, looked at through optical devices and studied through model photography, demonstrates how this technological progress paves the way for a scientific approach towards warfare. The evolution of the models thus illustrates how war was waged on a variety of scales and that its theatre was far from limited to the battlefield itself
