Which capability set does the Defense Threat Reduction Agency provide for technical reach-back?

• A. Cyber, Space, and Economic
• B. Medical and Public Health
• C. Aerospace and Defense Logistics
• D. Chem, Bio, Rad, and Nuc

Answer: (D)

The capability being tested is the ability to provide remote, expert support specifically for chemical, biological, radiological, and nuclear threats. DTRA’s technical reach-back means field teams can connect with specialists who can help identify materials, interpret sensors or lab results, assess exposure and risk, and guide protective measures, decontamination, and mitigation—all from centralized expertise in those CBRN domains. This focused reach-back support aligns with DTRA’s mission to counter and reduce CBRN threats, giving responders rapid access to the precise knowledge they need in those areas. Other domains like cyber, space, medical/public health, or logistics are outside this DTRA reach-back scope, as they involve different agencies and mission areas.
