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)

The concept being tested is arranging sensors so their coverage overlaps enough to remove gaps along the defense line. Overlapping coverage means each sensor’s detection area extends into its neighbors so there are no seams where a gap could exist. This creates continuous surveillance across the entire perimeter and improves reliability because if one sensor has a temporary issue, adjacent sensors still cover the area. The other terms don’t describe this sensor-coverage geometry: overlapping fires refers to weapons fires covering the same ground, not sensor fields; keep-out range is a safety/operational distance boundary; resilience is about the system’s ability to withstand and recover from disruption. So, overlapping coverage is the correct way to describe sensors arranged to provide seamless, continuous coverage.
