Which defense agency provides command-and-control and information-sharing capabilities?

• A. DIA, the Defense Intelligence Agency
• B. DLA, the Defense Logistics Agency
• C. DISA, the Defense Information Systems Agency
• D. DHA, the Defense Health Agency

Answer: (C)

Command-and-control and information-sharing depend on a secure, reliable communications and IT backbone that connects every part of the force so leaders can see the same situation and coordinate actions in real time. The Defense Information Systems Agency is responsible for building, operating, and defending the DoD Information Network and delivering the IT and communications services that enable joint command-and-control and information sharing across the department. This includes interoperable networks, secure messaging, and collaboration tools that ties together diverse units and services.

The other agencies have different primary roles: the Defense Intelligence Agency focuses on intelligence analysis and collection, the Defense Logistics Agency handles supply and logistics, and the Defense Health Agency provides medical services. These areas don’t centrally provide the DoD’s command-and-control and information-sharing capabilities.
