Which statement best describes redundant communications in combat networks?

• A. Single path reliability
• B. Encrypted channel only
• C. Multiple independent channels
• D. Manual signaling backups

Answer: (C)

Redundancy in combat networks means having multiple independent channels to keep communications flowing even if one path is disrupted. The core idea is independence and diversity: different media, routes, and frequencies that don’t share the same vulnerabilities. With multiple independent channels, a single failure—like damage to a line, a jam on one frequency, or a congested link—won’t knock out the entire network, so essential information can still get through.

This is why multiple independent channels is the best description. Simply relying on a single path creates a single point of failure. An encrypted channel focuses on confidentiality, not availability, so it doesn’t inherently provide redundancy. Manual signaling backups are slower, less scalable, and cannot sustain high-tempo operations the way automatic, diverse channels do.
