Which item is considered a component of decisive action involving national disaster response and civil support?

• A. Retrograde
• B. Tempo
• C. Defense Support to Civil Authorities (DSCA)
• D. Attack

Answer: (C)

The main idea here is that during national disaster response and civil support, the military has a formal way to assist civilian authorities. Defense Support to Civil Authorities is that mechanism. It describes how the Department of Defense can provide resources and capabilities—such as search and rescue, medical support, logistics, evacuation, and securing critical infrastructure—to help civilian agencies manage and respond to emergencies, under appropriate authority and coordination with state and local partners.

This makes it the best choice because it directly addresses civil support and disaster response, showing a clear, authorized way military assets contribute to decisive action in emergencies. The other terms describe different military concepts: retrograde is about withdrawing or redeploying forces, tempo concerns the speed and rhythm of operations, and attack refers to offensive action. None of those specifically capture the civil-support role described here.
