"Discussions of an emerging practice of 'gray zone' conflict have become increasingly common throughout the U.S. Army and the wider national security community, but the concept remains ill-defined and poorly understood. This monograph aims to contribute to the emerging dialogue about competition and rivalry in the gray zone by defining the term, comparing and contrasting it with related theories, and offering tentative hypotheses about this increasingly important form of state competition. The idea of operating gradually and somewhat covertly to remain below key thresholds of response is hardly new. Many approaches being used today -- such as support for proxy forces and insurgent militias -- have been employed for millennia. The monograph argues that the emergence of this more coherent and intentional form of gray zone conflict is best understood as the confluence of three factors. Understood in this context, gray zone strategies can be defined as a form of conflict that pursues political objectives through integrated campaigns; employs mostly nonmilitary or nonkinetic tools; strives to remain under key escalatory or red line thresholds to avoid outright conventional conflict; and moves gradually toward its objectives rather than seeking conclusive results in a relatively limited period of time. Having examined the scope and character of gray zone conflict, the monograph offers seven hypotheses about this emerging form of rivalry. Finally, the monograph offers recommendations for the United States and its friends and allies to deal with this challenge"--Publisher's web site.

National security threats facing the West are fundamentally changing. In this book, Elisabeth Braw offers the first sustained analysis of how new tactics in the gray zone between war and peace dangerously weaken liberal democracies. She discusses the breadth of gray-zone aggression and presents strategies for better defense against it.

China’s maritime “gray zone” operations represent a new challenge for the U.S. Navy and the sea services of our allies, partners, and friends in maritime East Asia. There, Beijing is waging what some Chinese sources term a “war without gunsmoke.” Already winning in important areas, China could gain far more if left unchecked. One of China’s greatest advantages thus far has been foreign difficulty in understanding the situation, let alone determining an effective response. With contributions from some of the world’s leading subject matter experts, this volume aims to close that gap by explaining the forces and doctrines driving China’s paranaval expansion, operating in the “gray zone” between war and peace. The book covers China’s major maritime forces beyond core gray-hulled Navy units, with particular focus on China’s second and third sea forces: the “white-hulled” Coast Guard and “blue-hulled” Maritime Militia. Increasingly, these paranaval forces, and the “gray zone” in which they typically operate, are on the frontlines of China’s seaward expansion.

One of the most surprising developments in Mexico's transition to democracy is the outbreak of criminal wars and large-scale criminal violence. Why did Mexican drug cartels go to war as the country transitioned away from one-party rule? And why have criminal wars proliferated as democracy has consolidated and elections have become more competitive subnationally? In Votes, Drugs, and Violence, Guillermo Trejo and Sandra Ley develop a political theory of criminal violence in weak democracies that elucidates how democratic politics and the fragmentation of power fundamentally shape cartels' incentives for war and peace. Drawing on in-depth case studies and statistical analysis spanning more than two decades and multiple levels of government, Trejo and Ley show that electoral competition and partisan conflict were key drivers of the outbreak of Mexico's crime wars, the intensification of violence, and the expansion of war and violence to the spheres of local politics and civil society.

The United States is entering a period of intensifying strategic competition with several rivals, most notably Russia and China. U.S. officials expect this competition to be played out primarily below the threshold of armed conflict, in what is sometimes termed the gray zone between peace and war. In this report, the authors examine how the United States might respond to Russian and Chinese efforts to seek strategic advantage through coercive actions in the gray zone, including military, diplomatic, informational, and economic tactics. The United States is ill prepared and poorly organized to compete in this space, yet the authors' findings suggest that the United States can begin to treat the ongoing gray zone competition as an opportunity more than a risk. Moreover, leaders in Europe and Asia view Russian and Chinese gray zone aggression as a meaningful threat and are receptive to U.S. assistance in mitigating it. In this report, the authors use insights from their extensive field research in affected countries, as well as general research into the literature on the gray zone phenomenon, to sketch out the elements of a strategic response to the gray zone challenge and develop a menu of response options for U.S. officials to consider.

Sponsored by the Army Capabilities Integration Center and in collaboration with the Joint Staff's Deputy Directorate for Global Operations (Strategic Multi-Layer Assessment Branch), this report examines the emergence of gray zone competition and conflict as important pacers for U.S. defense strategy. The authors argue that gray zone challenges are unique defense-relevant issues sharing three common characteristics-hybridity, menace to defense and military convention, and profound and paralyzing risk-confusion. This report and its authors offer an important opening venture into a vexing strategic question for senior defense and military leadership on the subject of gray zone threats. Namely, how can the American defense enterprise adjust to an era of relentless revisionist and rejectionist opposition to U.S. power? On the one hand, purposeful U.S. competitors pursue meaningful revision of the U.S.-led status quo through campaign-quality combinations of influence, intimidation, coercion, and aggression.
