What is the risk of over-reliance on communications in C2 and how can it be mitigated?

• A. Over-reliance on comms improves resilience; mitigate by centralizing control.
• B. If comms fail, C2 degrades; mitigate by redundancy, alternate means, exercises, and fallback procedures.
• C. Risk is negligible with encryption.
• D. If comms fail, C2 improves speed and resilience.

Answer: (B)

Relying too much on communications creates a vulnerability window: if links fail, command and control deteriorates because leaders can’t issue timely guidance or share the situation with subordinates. In combat, that loss of connectivity can slow decision cycles, muddy situational awareness, and leave units operating without coordinated direction. The best way to handle this is to build resilience through multiple lanes of communication and solid fallback methods. Use redundancy across different channels and paths—radio, satellite, wired, secure and non-secure when appropriate—and ensure there are alternate means of reaching units, such as visual signals, couriers, or preplanned hand signals for near-term actions. Regular exercises that stress comms and command in degraded conditions help teams validate continuity and reveal gaps. Finally, establish fallback procedures that delegate authority and pre-authorize actions so teams can proceed under a loss of contact, maintaining momentum and intent even when the primary links are down.
