What should effective command and control do?

• A. Swift, appropriate, decisive, harmonious, and secure action.
• B. Prolonged deliberation before each move.
• C. Isolated action without coordination.
• D. Rely exclusively on automated systems.

Answer: (A)

Effective command and control aims to produce action that is swift, appropriate, decisive, harmonious, and secure. In the dynamic environment Marines operate in, C2 must drive decisions and movements that keep tempo, maintain unity of effort, and protect information and assets.

Swift action keeps pace with changing conditions and preserves the initiative, so operations don’t stall waiting on lengthy review. Appropriate action ensures responses match the threat and risk, avoiding overreaction or underreaction. Decisive direction provides clear intent and guidance, reducing ambiguity for units across the force. Harmonious action synchronizes activities across maneuver, fires, intelligence, logistics, and support, ensuring the right things happen in the right order and at the right time. Secure action protects operations from disruption or adversary interference, including safeguarding communications, networks, and sensitive data.

The other options fail to meet these demands: slowing the process leads to missed opportunities and a loss of tempo; acting in isolation breaks coordination and unity of effort; and relying only on automated systems ignores human judgment, adaptability, and resilience needed in complex environments.
