We live in a digital world. This fact has significant consequences for warfare. Two technologies in particular, cyber and drones, feature in military and intelligence operations and in scholarship. In addition, a new vein of scholarship is examining how advances in artificial intelligence have the potential to shape the future of warfare. While scholars disagree about the consequences of these technologies for international politics, they tend to agree that their consequences are mediated by the ability of military organizations, whether state or nonstate actors, to use them effectively in relevant military scenarios and in the pursuit of political ends. Studying newer military technologies, with less empirical evidence than is available for technologies that have been around for decades, also generates methodological challenges for research.
