Moral competence is important for soldiers who have to deal with complex moral dilemmas in practice. However, openly dealing with moral dilemmas and showing moral competence is not always easy within the culture of a military organization. In this article, based on analysis of experiences during a train the trainer course on military ethics, we will describe the tensions between military and personal values on the one hand and the challenges related to showing moral competence on the other hand. We will explain these tensions and challenges by elaborating on various aspects of the military organization, such as being a soldier, group bonding, uniformity, hierarchy, lack of privacy and masculinity. Furthermore, we will demonstrate how moral competence can be addressed and fostered during the training by introducing specific interventions.
