Three-agent foot surveillance technique for tracking is known as which method?

• A. Detections Chain
• B. Surveillance Triangle
• C. Tracking Triad
• D. ABC Method

Answer: (D)

Three-agent foot surveillance trains observers to work as a tightly coordinated team, using three distinct roles labeled A, B, and C. The lead observer (A) keeps the target in close view, the second (B) shadows from a different angle to prevent gaps in coverage, and the third (C) stays back, ready to relay information, maintain communication, or take over if contact is lost. This arrangement creates redundancy and flexibility, so the group can track a moving target through turns, crowds, and obstacles without breaking contact or revealing watchers. The ABC Method is named to reflect this three-role setup—the positions are treated as a sequence or trio that together maintains continuous observation and rapid information handoff. That makes it the best answer for describing a three-agent foot surveillance technique for tracking. Other terms describe related ideas (different formations or concepts in surveillance), but they don’t reference the standardized three-agent labeling used here, so they aren’t the specific method described in this context.
