Examines several case studies of sustained campaigns of urban terrorism perpetrated by various domestic groups in the countries of India, Pakistan and Sri Lanka. Military operations in urban areas are among the most complex challenges confronting the U.S. Army. Compared to a number of other nations, the Army has relatively less experience operating in this environment. To that end, this monograph analyzes sustained campaigns of urban terrorism in Sri Lanka, India, and Pakistan, identifying key innovations of the militant organizations. It also details the three states' responses to the threats, noting successful as well as unsuccessful efforts.
