Federal Bureau of Investigation (FBI)


The FBI’s Weapons of Mass Destruction Directorate, or WMDD, builds a
cohesive and coordinated approach to incidents involving nuclear,
radiological, biological, or chemical weapons—with an overriding focus on

To do its job, the WMDD proactively seeks out and relies upon intelligence to
drive preparedness, countermeasures, and investigations designed to keep
threats from becoming reality. It also taps into the tactical and technical
expertise of other FBI operational and support divisions, embedding personnel
in these components as needed and coordinating investigations and
initiatives. Throughout these efforts, the WMDD supports the broader work of
the U.S. government as a leading partner and active contributor to policy
The FBI Laboratory uses cutting-edge science to solve cases and prevent acts
of crime and terror. It is a full-service operation, with some 500 scientific
experts and special agents working in a state-of-the-art facility in rural
Virginia, traveling the world over on assignment and providing forensic
exams, technical support, expert witness testimony, and advanced training to
Bureau personnel and partners around the globe.

The FBI Weapons of Mass Destruction Directorate (WMDD) leads the FBI’s
efforts to deny state and non-state sponsored adversaries access to WMD
materials and technologies, to detect and disrupt the use of WMD, and to
respond to WMD threats and incidents.

The WMDD coordinates the FBI’s WMD program through a multifaceted approach
that addresses all areas of the WMD incident spectrum from prevention through
response. It provides leadership, guidance, and expertise to the U.S.
government on WMD issues and influencing the development of interagency
policy, plans, and strategy. At the same time, WMDD is responsible for
coordinating WMD operational efforts through the FBI’s field-based WMD
coordinators and counterproliferation coordinators. To best address the many
requirements of the mission, the FBI approaches the WMD issue in terms of
four major functional categories: preparedness, countermeasures,
investigations/operations, and intelligence.

The FBI Laboratory has as its mission to apply scientific capabilities and
technical services to the collection, processing, and exploitation of
evidence for the FBI and other duly constituted law enforcement and
intelligence agencies in support of investigative and intelligence
priorities.  The Laboratory has specialized units that respond to incidents
and collect or facilitate the collection of evidence in the field. The
Evidence Response Team Unit supports Evidence Response Teams in all 56 FBI
field offices. The Explosives Unit specializes in evidence involving
explosive and incendiary devices, and the Hazardous Materials Response Unit
provides support at scenes involving chemical, biological, radiological, and
nuclear materials. The Photographic Operations and Imaging Services Unit and
the Special Projects Unit document the scene and collect data for such uses
as crime scene reconstruction, courtroom exhibits and testimony, and forensic
facial imaging.
