This thesis aims to describe American Military Chaplains’ thoughts and concerns on secularism and religious pluralism in the Millennial generation. The goal is to analyze how a potential change in this generation affects the chaplain’s role. The method is in-depth semi-structured interviews with three chaplains from different service branches. The main finding is that they detect a substantial decrease in religiousness, which follows overall trends in society. Their experience is not that pluralism is gaining substantial ground, rather it is that a large portion of the troops are indifferent to religion. Even so, they do not experience a decrease in interest or need for their services, since counselling is an increasing part of their workload. The ambiguity of their role is mostly perceived as a challenge to balance their religious task with non-religious counselling/coaching and practical duties as an officer.
