Technical Operations Group
Deploying the most sophisticated technologies available, the Technical
Operations Group (TOG) provides investigative and intelligence support for
the USMS and USMS-led fugitive task forces. TOG also provides
assistance when requested by other federal, state, and local law
enforcement agencies to solve complex criminal investigations or crimes of
violence. In recent years, TOG has been delegated as the lead
investigative element in technical surveillance for many high profile
investigations including Rafael Resendez-Ramirez (the Railway Killer),
the escapee known as the Texas Seven, and the Beltway Snipers.
Electronic Surveillance Branch
The Electronic Surveillance Branch (ESB)
provides covert investigative and intelligence support for Marshal's
Service's major case and 15 Most Wanted fugitive investigations.
ESB personnel, in addition to investigative operations, help prepare court
orders, serve as expert witnesses in the field of electronic surveillance,
and train law enforcement personnel from the United States and the
international law enforcement community in the use of electronic
surveillance.
Air Surveillance Branch
The TOG Air Surveillance Branch provides
aerial surveillance, electronic tracking, and other aerial platforms
functions in support of Marshals Service operations. TOG aircraft
provide vital intelligence during the investigation and arrest of some of
the country's most dangerous fugitives.
Tactical Support Branch
The Tactical Support
Branch encompasses Operational Wireless Communications Support (OWCS),
non-judicial Technical Surveillance Counter Measures (TSCM), and
non-cellular radio frequency direction finding. Tactical Support also
provides support for video and audio surveillance, alarms, and other
electronic surveillance measures as they relate to Enforcement Operations,
Force Protection, Protective Operations, Judicial Security, and other
special operations and events. Tactical Support works closely with other
federal, state, and local agencies, as well as the private sector, to
develop and deploy electronic measures to better support the diverse
missions of the United States Marshals Service.
Analysis and
Intelligence Group
The
Analysis and Intelligence Directorate (A&I) purpose is to provide
intelligence and investigative support to all TOG components, USMS
districts, and divisions. In addition, A&I is the primary liaison to the
U.S. Intelligence Community.
