Core values are the heart and soul of U.S. military Services and their cultures. Military organizational, strategic, operational, and tactical strength lies in the degree to which the Services’ systems, processes, and behaviors of personnel align with their stated core values, the collective practice of which creates organizational culture. Yet even with the emphasis on core values such as respect and selfless service, the Department of Defense (DOD) continues to experience toxic and counterproductive behaviors that sabotage culture and values, as well as performance, productivity, force protection, health, readiness, and actions of personnel.1 Although DOD has not conducted comprehensive research on toxic behavior, there is extensive private-sector research regarding the impact, cost, tolerance, enabling, and reduction of toxicity. This article applies private-sector research to assess DOD policies and practices and to recommend courses of action. Although the implications and cost of toxicity are beyond the scope of this article, a brief discussion is relevant for demonstrating its significance. Private-sector research has identified relationships between toxic behaviors and adverse effects on mental and physical health (including suicide, stress-related illness, and post-traumatic stress), increasing demands on an already overburdened healthcare system; job satisfaction and commitment; individual and collective performance (cognition and collaboration); employee turnover; and the creation of an organizational culture that tolerates other inappropriate behaviors including sexual harassment and discrimination.2 In addition to the impact on direct targets of toxicity, research has identified the transmission of adverse effects to bystanders and family members.3
