Which term describes sensors arranged to eliminate seams in the defense by providing continuous coverage?

• A. Overlapping Fires
• B. Keep-Out Range
• C. Resilience
• D. Overlapping Coverage

Answer: (D)

This is about creating a continuous sensing envelope around the defended area by overlapping the sensors’ detection fields. When the coverage zones of individual sensors intersect, there are no gaps or seams where a target could pass unseen. That overlap also adds redundancy—if one sensor is momentarily degraded or misses something, neighboring sensors still monitor the area, maintaining continuous awareness. The other terms don’t describe this arrangement: overlapping fires refers to weapon fire coverage, not sensor coverage; keep-out range is a boundary for where friendly forces can operate; resilience is about the overall ability to withstand and recover from disruption, not specifically how sensors are arranged to cover gaps. So, overlapping coverage precisely captures the idea of continuous, seam-free surveillance.
