Intelligence and Special Operations Forces (SOF) play critical roles in combating terrorist threats. To be sure, both intelligence and SOF have been instrumental in addressing all major threats to US national security for the past several decades, but since 9/11 both have increased in importance to U.S. policy makers as they address America's new enemies; transnational, non-state actors with global reach and who are seeking access to weapons of mass destruction. The Intelligence and Special Operations Forces in Counterterrorism Workshop describes both intelligence and SOF capabilities and actions in countering terrorist operations and activities. With regards to intelligence the workshop discusses the "intelligence cycle," the full gamut of intelligence gathering disciplines will be discussed. However, signals, technical, and human intelligence gathering will be emphasized. With regards to special operations forces (SOF), all special operations-type units are introduced emphasizing their counterterrorism capabilities and operations. The workshop heavily relies on case studies and guest lecturers to reflect the challenges and opportunities facing the intelligence and special operations communities, both individually and collectively in America's counterterrorism efforts.
