Which organization provides technical reach-back for CBRN threats in the chemical, biological, radiological, and nuclear domains?

• A. National Security Agency
• B. Defense Threat Reduction Agency
• C. Centers for Disease Control and Prevention
• D. FEMA

Answer: (B)

Technical reach-back for CBRN threats means having a dedicated channel to obtain specialized scientific and engineering guidance during incidents or planning. The Defense Threat Reduction Agency provides this kind of support as the DoD’s primary agency for countering weapons of mass destruction. It brings integrated technical expertise across chemical, biological, radiological, and nuclear domains, covering threat assessment, modeling, laboratory analysis, risk assessment, and decision support for protective and response options. In practice, DTRA acts as the expert backstop that military and other partners can consult to navigate complex CBRN scenarios. Other agencies don’t fulfill this cross-domain technical reach-back role. The National Security Agency concentrates on signals intelligence and cyber operations rather than CBRN technical guidance. The Centers for Disease Control and Prevention focuses on public health and medical countermeasures within civilian health, not the broad CBRN technical reach-back for weapons-related threats. FEMA handles domestic emergency management and disaster response, but it does not provide the specialized CBRN technical reach-back function across the chemical, biological, radiological, and nuclear spectrum.
