As the Army found itself caught up in debates about a ‘kinder, gentler military’, Army leaders reacted by emphasising cultural change. Part of this cultural shift came from the bottom up, as commanders in elite combat units showed a new interest in the psychology of killing and brought in consultants to lecture their instructors on how to more effectively inculcate a willingness to kill. Much of it came from the top, though. General Eric Shinseki controversially mandated that all soldiers would wear black berets as their working headdress to symbolise a new Army culture, and he commissioned a study on the ‘warrior ethos’ and begin to enshrine that ethos into Army doctrine and training. This warrior ethos – the idea that all soldiers are de facto heroic and potential Rangers – had the goal of democratizing notions of soldiering within the Army. However, not only did the warrior ethos require all soldiers to psychologically orientate themselves towards combat, but one of the unintended consequences of the decision may have been to help to put the American soldier a little higher on the pedestal of public opinion and inadvertently widen the gap between soldier and citizen.

The Introduction sketches out the key themes of the book, offers a justification for focusing on the identity of the American soldier as a key issue in the Army’s post–Cold War transformation and introduces the reader to literature on ‘warrior culture’. Just as Army leaders and ordinary soldiers often meant very different things when they spoke about warriors, so contemporary historians, anthropologists and classicists have used the term in various ways. Thus, the latter part of the Introduction spends some time examining how the term has evolved and been deployed in different contexts.
