This report from the CSIS International Security Program analyzes the U.S. military forces in FY 2020, their composition, new initiatives, long-term trends, and challenges, as the United States attempts to align its forces with a strategy of long-term great power competition.

CSIS senior adviser Mark Cancian annually produces a series of white papers on U.S. military forces, including their composition, new initiatives, long-term trends, and challenges. This report is a compilation of these papers and takes a deep look at each of the military services, the new Space Force, special operations forces, DOD civilians, and contractors in the FY 2021 budget. This report further includes a foreword regarding how the Biden administration might approach decisions facing the military forces, drawing on insights from the individual chapters.

This timely study examines the Defense Department’s FY 2017 budget proposal for the size and shape of military forces; what that proposal means for cost, strategy, and risk; and challenges the proposal faces in implementation. The study covers all four military services plus government civilians, contractors, and department-wide initiatives.

A RAND study analyzed Chinese and U.S. military capabilities in two scenarios (Taiwan and the Spratly Islands) from 1996 to 2017, finding that trends in most, but not all, areas run strongly against the United States. While U.S. aggregate power remains greater than China’s, distance and geography affect outcomes. China is capable of challenging U.S. military dominance on its immediate periphery—and its reach is likely to grow in the years ahead.

In 1950, when he commissioned the first edition of The Armed Forces Officer, Secretary of Defense George C. Marshall told its author, S.L.A. Marshall, that "American military officers, of whatever service, should share common ground ethically and morally." In this new edition, the authors methodically explore that common ground, reflecting on the basics of the Profession of Arms, and the officer's special place and distinctive obligations within that profession and especially to the Constitution.

The U.S. military has been continuously engaged in foreign conflicts for over two decades. The strains that these deployments, the associated increases in operational tempo, and the general challenges of military life affect not only service members but also the people who depend on them and who support them as they support the nation â€" their families. Family members provide support to service members while they serve or when they have difficulties; family problems can interfere with the ability of service members to deploy or remain in theater; and family members are central influences on whether members continue to serve. In addition, rising family diversity and complexity will likely increase the difficulty of creating military policies, programs and practices that adequately support families in the performance of military duties. Strengthening the Military Family Readiness System for a Changing American Society examines the challenges and opportunities facing military families and what is known about effective strategies for supporting and protecting military children and families, as well as lessons to be learned from these experiences. This report offers recommendations regarding what is needed to strengthen the support system for military families.
