Explain redundancy in C2 systems.

• A. Having multiple pathways, backups, and alternative means to maintain connectivity if one system fails.
• B. Relying on a single communication path to simplify operations.
• C. Eliminating backup systems to save resources.
• D. Only using redundant hardware with no software backups.

Answer: (B)

Redundancy in C2 systems means building resilience by providing multiple pathways, backups, and alternative means to stay connected even if one part of the system fails. In a command and control context, that continuity is critical because decisions must be informed and transmitted under a variety of conditions—jamming, damage, or outages can happen. So you design the network with diverse transmission paths (different frequencies or networks), independent backup systems, and alternative modes of communication so no single failure shuts down the flow of information or the commander’s ability to control operations.

This concept is best captured by describing having multiple pathways and backups to maintain connectivity when one link fails. The other ideas undermine resilience: relying on a single communication path invites a single point of failure; eliminating backups saves resources but weakens continuity; using only hardware redundancy without software backups leaves gaps in recoverability and adaptability.
