The US Army and Social Change offers historical context for ongoing, contemporary debates over the proper relationship of the US military to social change and social issues. Contributors look beyond the debate over whether the Army should be a site of social experimentation to argue that it always has and likely always will be. Examining specific cases from the twentieth century, the essays in The US Army and Social Change analyze army responses to critical questions about who should serve, what roles individuals and groups should play, and what rights each deserves—always in the context of the US Army's mission of national defense.
