Building the capacity of Afghan special operations forces (SOF) is a key goal of the United States and its coalition partners. This report summarizes key partnering practices and presents findings from SOF partnership case studies in Afghanistan, Iraq, and Colombia. The goal is to identify best practices to benefit the development of Afghan SOF, as well as for special operations partnerships beyond Afghanistan.

Through an analysis of transnational criminal networks originating in South America, this report presents operational characteristics of these networks, strategic alliances they have established, and the multiple threats that they pose to U.S. interests and to the stability of the countries where they operate. It also identifies U.S. government policies and programs to counter these networks and examines the military’s role in that context.

Looking to the 2030–2040 time frame, U.S. policy and military strategy will need to strike a balance among maintaining a cooperative relationship with China, deterring Chinese aggression in regional disputes, and preparing for the possibility that China could become more assertive. The U.S. Army will have an important role to play in preparing for these developments and for protecting and furthering U.S. interests in the region.

This RAND report examines the U.S. Army role in Southeast Asia. Under current benign conditions, efforts should focus on supporting defense reform, addressing transnational threats, and balancing China. If the outlook deteriorates, the United States should increase security cooperation, conclude new regional basing agreements, expand disaster assistance, and create policies to encourage risk-averse Chinese behavior.
