Which foot surveillance configuration is considered optimal?

• A. Three-Person (ABC Method): optimal number of surveillants
• B. One-Person: avoid this if possible
• C. Two-Person: Better than one surveillant
• D. Four-Person: Excessively many surveillants

Answer: (A)

Having enough personnel to maintain constant sight of the subject while staying discreet and mobile is the key idea. A three-person foot surveillance setup, often referred to as the ABC method, provides the best balance of coverage, stealth, and maneuverability. With three, one member maintains the lead and keeps the subject in view, a second remains close enough to sustain a solid sightline and relay information, and a third watches the surrounding environment for openings, side streets, or potential escape routes. This arrangement allows quick adjustments as the subject moves around corners, through crowds, or past obstacles without losing contact. If you try with just one, you’re highly vulnerable to losing contact the moment the subject is obscured by a doorway, vehicle, or crowd. With two, you gain some redundancy but can still miss a turn or be unable to cover multiple angles at once. With four or more, movement becomes cumbersome, it draws attention, and coordination suffers, diminishing stealth and speed. Three provides the optimal balance of staying on target, staying concealed, and adapting to changing conditions.
