Military applications of technologies for enhancing or producing vision play a key role in composing contemporary security, as such technologies are deployed to make security sense of everyday sociality, of battlefields, and of much in between these extremes. In this article, I set out to recompose militarised techno-vision through the public detritus left by its heterogenous development, use, and appropriation. I argue that as an heterogenous and amalgamated object, military techno-vision can be composed by speaking the stories of its leftovers, and that this composition is characterised by and in turn characterises a longstanding dilemma between fact and vision – between the ambiguity that is constitutive of the human practices of visual perception and image-making, and the desire for machines that can produce visual ‘actionable intelligence’ that can underpin security decisions. Discourses, practices, and regimes of visibility are deployed alongside technologies to occlude the ambiguity of technological vision and sustain the imaginary of technologically altered vision as neutral production of military or security facts.
