Critical Incident Response Group


The Critical Incident Response Group (CIRG) facilitates the FBI's rapid response to, and the management of, crisis incidents. CIRG was established in 1994 to integrate tactical and investigative resources and expertise for critical incidents which necessitate an immediate response from law enforcement authorities. CIRG will deploy investigative specialists to respond to terrorist activities, hostage takings, child abductions and other high-risk repetitive violent crimes. Other major incidents include prison riots, bombings, air and train crashes, and natural disasters.

Each of the three major areas of CIRG -- the Operations Support Branch, the Tactical Support Branch, and the National Center for the Analysis of Violent Crime -- furnishes distinctive operational assistance and training to FBI field offices as well as state, local and international law enforcement agencies. CIRG personnel are on call around the clock, seven days a week, to respond to crisis incidents.
