Counterterrorism Operations

Counterterrorism operations are the actions a government takes to find, disrupt, and stop terrorist groups and plots. They include investigations, intelligence sharing, financial tracking, border and travel screening, and military action overseas. The FBI, the Department of Homeland Security, intelligence agencies, the Pentagon, and state and local police all take part.

People usually ask how these agencies divide the work, how the military's role differs from that of law enforcement, and how the government fights terrorism at home and abroad. They also ask how operations are coordinated and what limits apply to them.
