The science of ammunition lethality is a field that seeks to define the point at which military ordnance takes life and produces death. By historicising lethality's epistemology, I reveal the intellectual fissures and scientific uncertainties that have been reified and embedded into contemporary conceptions of military power. This not only tells us something about the processes by which science is subordinated to war, but also offers a new lens from which to consider the way knowledge claims about battle are co-constructed and legitimated through military practices. As a result, this article places science back into a narrative that otherwise frames the ontology of war in terms of fighting.
