The previous chapters advanced the empirical and theoretical understanding of moral, political and societal dimensions of military moral injury, and in doing so, contributed to an interdisciplinary conceptualization of moral injury and to theory on trauma and post-traumatic stress disorder – PTSD – in general. This chapter takes stock of the book’s key insights and brings them together into an interdisciplinary concept of moral injury. Also, it discusses how stories of moral injury make manifest moral tensions that military practice and its sociopolitical aspects pose to all soldiers, whether or not they develop moral injuries as a result of these tensions. Finally, it reflects on how such stories offer insight into basic vulnerabilities to moral injury that most people have in common, whether or not they are soldiers.
