Many militaries envision a technologically advanced future with a strong innovative capability and therefore invest in so-called innovation hubs focused on experimenting with new modes of operation with drones and (semi-)autonomous vehicles. However, there appears to be a discrepancy between these military visions and soldiers’ lived experiences on the ground. This article presents an ethnographic study of one innovation hub: the Robots and Autonomous Systems unit of the Dutch Army. Examining this unit through an analytical framework of sociotechnical imaginaries and expectations, we first outline how “innovation” and “military” imaginaries are integrated so that technological innovation is presented as necessary, desirable, and inevitable for military futures. Second, we explore soldiers’ experiences of military innovation, identifying friction between the strategic and operational levels. At the strategic level, soldiers experience meaning and purpose in their work whereas, at the operational level, soldiers’ expectations, practices, and experiences do not align with the “innovative military future” imaginary, resulting in disillusionment. With this empirical study, we contribute to a better understanding of how large-scale visions of technological “progress” play out in military practice.
