The aim of this paper is to examine the usefulness of the somewhat related notions of integrity, moral courage, and Innere Führung (the leadership concept used by the German military) as a means of making military personnel behave ethically. Of these three notions, integrity is mentioned most often within military organizations, and the largest part of what follows is therefore devoted to a description of what integrity is, and what the drawbacks of this notion are for the military. This will lead us to conclude that integrity in its most common meaning is too vague and subjective to be of much use to the military. It is because of these drawbacks that this paper looks into moral courage and Innere Führung as possible alternatives for integrity
