The Social Network Analysis Reachback Capability is a currently being used to support U.S. forces in Afghanistan. SNARC is used to provide answers to specific questions from the International Security Assistance Forces in Afghanistan about the country’s social networks. SNARC is used to analyze survey data about public opinion in Afghanistan, such as the level of trust the population has in the local government. It also looks at what factors contribute to specific activities, such as roadside bomb attacks directed against coalition forces, or the drug trade. SNARC grew out of the Defense Department’s Human Social Cultural Behavioral Modeling program, which has supported Carnegie Mellon and other universities involved in social network analysis.
