What survey technique is used when a recon and surveillance element enter a contaminated area?

• A. Near side - Far Side
• B. Zone Recon
• C. Star
• D. Box

Answer: (A)

The technique focuses on entering a contaminated area in two stages from the safer, near edge toward the farther, more illuminated area. By starting at the near side, the recon and surveillance team can observe boundary conditions, verify contamination levels, and establish decontamination procedures before pushing deeper. This phased approach minimizes risk to personnel and provides reliable data on how far the contamination extends, which is essential for planning further movement and safe egress. Other patterns are general search or zone coverage methods that don’t address the specific sequence needed for entering a contaminated zone. Zone Recon methodically covers an area in defined sectors, but it doesn’t prescribe the near-to-far entry sequence for initial contamination assessment. Star and Box patterns are movement schemes used for surface searches around a central point or along defined perimeters, not for progressive entry into contaminated terrain.
