This chapter challenges simplistic views and aims to show that nationalism plays a marginal role in the combat zone. It argues that in most cases, the warrior ethos is not linked directly to nationalist ideas and practices. Instead, the majority of combatants fight from a sense of moral obligation and emotional attachment to their micro-level groups. However, this is not to say that nationalism is irrelevant in the context of violent conflicts. On the contrary, the chapter aims to show how nationalist ideas and practices permeate the organisational and ideological scaffolds of the wider social world. It argues that nationalism is primarily generated and reproduced in civilian institutions and other domains of civilian life.
