A Military Guide to Terrorism in the Twenty-First Century
This document is intended as a resource to inform U.S. military personnel of the nature and characteristics of the terrorist threat in the current operational environment. Its purpose is to provide unit leaders, planners and commanders with a tool for understanding the nature of the terrorism and identifying the threat of terrorism to their units. It provides information for leaders to conduct realistic evaluations of risk and vulnerability to their units, and details probable circumstances in which U.S. military units can expect terrorist operations against them and likely motivations for such operations. This document is not intended to be a counter-terrorism "howto" manual, or to replace current training and intelligence products dealing with terrorism.
