Numerous factors are known to impact human decision-making: fatigue, stress, fear, sleep deprivation, organizational culture, ethics, and even substances consumed, among others. Making decisions within the context of a military operation poses exceptional challenges. Time constraints are consistently tight, and military personnel often contend with physical and mental exhaustion, along with substantial stress and fear. Our proactive strategies for addressing these hurdles predominantly revolve around educating military personnel, incorporating both theoretical training and immersive simulations that may include different types of (...) war games, role playing and VR applications that mimic real-world challenges. However, can we extend our efforts further to ensure that military personnel surmount difficulties and consistently make morally and legally sound decisions amidst exceptional situations? Moreover, where does trust lie: in the insights of a comrade, a commanding officer, or the guidance provided by sophisticated algorithms and Artificial Intelligence (AI) systems? Could AI potentially outperform human guidance when it comes to elevating the ethical and legal discernment of military personnel amid the intensity of combat situations? (shrink)

A recent empirical study has argued that experts in the ethics or the law of war cannot reach reasonable convergence on dilemmas regarding the number of civilian casualties who may be killed as a side effect of attacks on legitimate military targets. This article explores the philosophical implications of that study. We argue that the wide disagreement between experts on what in bello proportionality means in practice casts serious doubt on their ability to provide practical real-life guidance. We then suggest (...) viewing in bello proportionality through the prism of virtue ethics. (shrink)

Until recently most militaries tended to see moral issues through the lens of rules and regulations. Today, however, many armed forces consider teaching virtues to be an important complement to imposing rules and codes from above. A closer look reveals that it is mainly established military virtues such as honour, courage and loyalty that dominate both the lists of virtues and values of most militaries and the growing body of literature on military virtues. Although there is evidently still a role (...) for these traditional martial virtues, it is equally evident that they are not particularly relevant to, for instance, military personnel operating drones. This chapter looks into the ethics of unmanned warfare from the perspective of military virtues and military ethics education, and addresses the question of what we need to solve that just-mentioned misalignment: 1) a new set of virtues; 2) a different interpretation of the existing virtues; or 3) a different approach altogether, that is, an alternative to teaching virtues? That we have to think about such questions is at least partly because unmanned systems bring risk asymmetry in war to a new level, making warlike virtues such as physical courage by and large obsolete. The last section of this chapter therefore addresses the question: to what extent does the possibility of riskless warfare makes drone use ‘virtue-less’? (shrink)
