Violent nonstate actors must have the resources to carry out their activities. Disrupting their financing plays a critical role in degrading these groups. It is not, however, always obvious which tools are effective and which would be counterproductive. This report presents five cases describing how five groups financed their activities, the effectiveness of various tools to disrupt that financing, and how the Army can contribute to the effort.

The authors analyze the prospect that Iran will further invest in Yemen's Houthis and develop them into an enduring proxy group. The authors examine the Houthi movement's history, the Houthis' current relations with Iran, Iran's history of proxy development, and the trajectory of the Houthi-Iran relationship, and then pose scenarios for the future. The report should be of interest to a wide audience in the foreign policy and defense community.

The foreign policy and defense communities have intensively debated the efficacy of low-cost and small-footprint military options for crises such as those in Afghanistan, Iraq, Libya, Somalia, Syria, and Yemen. This report provides a statistical analysis of hundreds of cases, supplemented by case studies, to evaluate the strategic effects of each option across a range of irregular warfare operations and in a range of operational environments.

The first textbook to bring together the linguistics of both BSL and ASL, this accessible book provides a uniquely international and comparative introduction to the structure and use of signed languages. Presupposing no prior knowledge, it covers all levels of linguistic structure: phonetics/phonology, morphology, the lexicon, syntax, semantics and discourse. Photographic illustrations of BSL and ASL signs feature throughout every chapter, and are linked to over 150 online videos, making this a clear and immersive resource for anyone interested in sign language linguistics. End of chapter exercises, questions for discussion and annotated further reading suggestions allow students to fully engage with the material they have read, and to extend their learning independently.

This report presents analysis and characterization of climate change's second-order impacts on three systems that are critical for human survival and security--water, food, and energy--in the U.S. Central Command's (CENTCOM's) area of responsibility. Recommendations for CENTCOM account for the role in which the U.S. Department of Defense can contribute expertise, tools, and resources to address the climate and conflict risk associated with these systems.

Yemen's civil war entered its sixth year in 2021. This report describes the challenges facing efforts to achieve an enduring peace in Yemen and outlines constructive steps the international community can take to achieve an enduring peace.

The United States has sought to combat security threats in Africa principally by supporting partner governments, and security sector assistance (SSA) has been one of the primary tools it has used. A RAND Corporation study used statistical models to evaluate the impact that U.S.-provided SSA has had on political violence in Africa--in particular, the incidence of civil wars and insurgencies, terrorist attacks, and state repression.
