This monograph investigates the nature of the resistance within the United States Army to the inclusion of homosexuals into the wider force and the preparation necessary at the macro level for potential social change should Congress repeal US Code Title 10, Subtitle G, 654 (also known as, "Don't Ask, Don't Tell"). Understanding the historical nature of masculinity, manliness, and the ideals of the citizen-soldier coupled with keen observation of the actions taken by the armed forces of the United Kingdom, Canada, and Australia during their respective transitions to the acceptance of homosexuals in their armed forces, enables the United States Army to develop effective courses of action in order to prepare for the social challenges it will face. Effective leadership, implementation of guiding principles for transition and an adapted Code of Social Conduct are paramount to ensuring fair and equitable management of social change for both heterosexual and homosexual soldiers alike."
