The Office of the Under Secretary of Defense (Personnel & Readiness), referred to throughout this report as P&R, is responsible for the total force management of all Department of Defense (DoD) components including the recruitment, readiness, and retention of personnel. Its work and policies are supported by a number of organizations both within DoD, including the Defense Manpower Data Center (DMDC), and externally, including the federally funded research and development centers (FFRDCs) that work for DoD. P&R must be able to answer questions for the Secretary of Defense such as how to recruit people with an aptitude for and interest in various specialties and along particular career tracks and how to assess on an ongoing basis service members' career satisfaction and their ability to meet new challenges. P&R must also address larger-scale questions, such as how the current realignment of forces to the Asia-Pacific area and other regions will affect recruitment, readiness, and retention. While DoD makes use of large-scale data and mathematical analysis in intelligence, surveillance, reconnaissance, and elsewhereâ€"exploiting techniques such as complex network analysis, machine learning, streaming social media analysis, and anomaly detectionâ€"these skills and capabilities have not been applied as well to the personnel and readiness enterprise. Strengthening Data Science Methods for Department of Defense Personnel and Readiness Missions offers and roadmap and implementation plan for the integration of data analysis in support of decisions within the purview of P&R.

This Congressionally-mandated report identifies areas for further cooperation with Russia and other states of the former Soviet Union under the Cooperative Threat Reduction (CTR) program of the Department of Defense in the specific area of prevention of proliferation of biological weapons. The report reviews relevant U.S. government programs, and particularly the CTR program, and identifies approaches for overcoming obstacles to cooperation and for increasing the long-term impact of the program. It recommends strong support for continuation of the CTR program.

This important report was issued by the Department of Defense in June 2019. The Indo-Pacific is the Department of Defense's priority theater. The United States is a Pacific nation; we are linked to our Indo-Pacific neighbors through unbreakable bonds of shared history, culture, commerce, and values. We have an enduring commitment to uphold a free and open Indo-Pacific in which all nations, large and small, are secure in their sovereignty and able to pursue economic growth consistent with accepted international rules, norms, and principles of fair competition. The continuity of our shared strategic vision is uninterrupted despite an increasingly complex security environment. Inter-state strategic competition, defined by geopolitical rivalry between free and repressive world order visions, is the primary concern for U.S. national security. In particular, the People's Republic of China, under the leadership of the Chinese Communist Party, seeks to reorder the region to its advantage by leveraging military modernization, influence operations, and predatory economics to coerce other nations. In contrast, the Department of Defense supports choices that promote long-term peace and prosperity for all in the Indo-Pacific. We will not accept policies or actions that threaten or undermine the rules-based international order - an order that benefits all nations. We are committed to defending and enhancing these shared values.China's economic, political, and military rise is one of the defining elements of the 21st century. Today, the Indo-Pacific increasingly is confronted with a more confident and assertive China that is willing to accept friction in the pursuit of a more expansive set of political, economic, and security interests. Perhaps no country has benefited more from the free and open regional and international system than China, which has witnessed the rise of hundreds of millions from poverty to growing prosperity and security. Yet while the Chinese people aspire to free markets, justice, and the rule of law, the People's Republic of China (PRC), under the leadership of the Chinese Communist Party (CCP), undermines the international system from within by exploiting its benefits while simultaneously eroding the values and principles of the rules-based order.This compilation includes a reproduction of the 2019 Worldwide Threat Assessment of the U.S. Intelligence Community. 1.
