Research and recent nationwide media coverage have asserted that sexual harassment and assault (SH/SA) in the military is a serious problem that has yet to be adequately addressed and remedied. The Defense Manpower Data Center (DMDC) produced the 2006 and 2010 Workplace and Gender Relations Surveys of Active Duty Members (WGRA), a governmental survey that examined workplace SH/SA. This dissertation investigates how gender, race, rank, and branch of military service were associated with SH/SA. It also examines organizational tolerance of sexual harassment and assault (OTSH) by the perception of the military's reporting barriers and their ability to stop SH/SA, the dissemination of knowledge, the pertinence of SH/SA training, and whether SH/SA has been more or less of a problem within the prior four years of each survey. The 2006 WGRA had an analytic sample size of 30,633, and the 2010 WGRA had an analytic sample size of 30,362. Proportions, logistic regression, and hierarchical multiple regression analysis of SH/SA indexes were utilized to examine whether differences in experiences of SH/SA existed by gender, race, rank, and service. Multivariate analyses and logistic regression were utilized to study perceptions of OTSH and the military's response to SH/SA. Results revealed that being female, a minority, in a lower rank, and in the Army, Marines and Navy ("the Terrible Three") is associated with higher risk of SH/SA victimization. These groups therefore have less favorable perceptions of the efficacy of the military's ability to ameliorate this problem with its policies and training.
