What roles do C2 nodes play in a networked C2 system?

• A. Nodes perform data collection and execution control only.
• B. Nodes act solely as relays for messages.
• C. Nodes generate all orders independently without human input.
• D. Nodes perform data collection, processing, decision support, communication relay, and execution control, enabling command-to-action loops.

Answer: (D)

The concept being tested is that C2 nodes are multi-function components that support the entire command-to-action loop. They don’t just gather data or just relay messages; they collect data from assets and sensors, process and correlate it to provide situational awareness and decision support, relay communications across the network, and perform execution control by issuing commands to targets and ensuring those commands are carried out in the intended sequence and timing. This integrated capability enables a continuous loop from sensing to decision to action. The other options are narrower or misleading: restricting roles to data collection and execution control omits processing and decision support and relay functions; describing nodes as merely relays ignores sensing and execution control; and claiming orders are generated independently without human input ignores the human-in-the-loop nature of typical command-and-control operations and the need for oversight and validation in most scenarios.
