In recent years, IDA’s research has focused increasingly on support for ongoing military operations. Our analysts have deployed to war zones to help U.S. commands assess and formulate approaches to countering insurgents and to maintain stability. At home, IDA researchers have examined a wide variety of related issues, such as improving U.S. capabilities to detect improvised explosive devices (IEDs). Other studies have been aimed at understanding emerging security challenges, building partner capacity, and examining threat financing and potential counters. This edition of Research Notes highlights some of these efforts.
