Presently, there are HMRTs
in 27 of the FBI's 56 field offices, plus an added three satellite HMRTs
in the Anchorage, Honolulu, and San Juan Field Offices.
As a result, the JTTF opened a WMD investigation, and the HMRU and HMRT members from the Norfolk Field Office searched for materials associated with the production of ricin.
The more than 350 response personnel currently assigned to the HMRTs require response equipment, medical monitoring, and specialized training.
During the search process, HMRU and EU provided the scientific and technical oversight to assess and evaluate all of the hazardous and explosive materials, and the WFO HMRT
conducted all search tactics based on the continual scientific and technical assessment by HMRU and EU.
