The '''Counterterrorism Division''' ('''CTD''') is a division of the [[FBI National Security Branch|National Security Branch]] of the [[Federal Bureau of Investigation]]. CTD investigates [[Terrorism in the United States|terrorist]] threats inside the United States, provides information on terrorists outside the country, and tracks known terrorists worldwide. In the wake of the [[September 11 attacks]] in 2001, CTD's funding and manpower have significantly increased. 

The Division employs counterterrorism field operations organized into squads, the number of which varies according to the amount and diversity of activity in the [[List of FBI Field Offices|local field office's]] jurisdiction. Larger field offices, such as [[Los Angeles]], maintain counterterrorism squads for each major terrorist group, as well as for domestic terrorism and terrorist financing, while smaller field offices combined such responsibilities across two to three squads.
