Surveillance and Counter-Surveillance Techniques

What this domain tests

Tradecraft plus discipline: planning, movement, documentation, and knowing when to break off. Maine exam items favor judgment questions over gadget trivia.

Planning

  • Build a subject file: description, vehicle and plate, residence, work, known associates, routines, and restrictions.
  • Reconnoiter the start point so you do not arrive cold.
  • Confirm legal limits: no trespass, no entry onto posted property, no device attached to a vehicle without authority, no conduct that reads as stalking.
  • Kit: charged cameras with time stamping, log, fuel, change of outerwear, backup vehicle or driver.

Movement

  • Vehicle follows use leapfrog and hand-off so no car stays in the mirror; keep one or two cars between you and the subject.
  • At choke points, drop back and pick up again rather than closing distance.
  • Static surveillance at a known address beats a risky follow.
  • Foot surveillance keeps at least a block; never make eye contact or match pace.

Counter-surveillance

  • Subjects test for tails: sudden U-turns, stopping without reason, driving past their own turn.
  • Watch for the same vehicle appearing across days; vary cars and routes, and never post case details online.

Worked example

The subject pulls into a dead-end residential street. Reasoning: entering behind him guarantees detection and risks a confrontation on private property. Stop short, log the time and address, watch from a lawful position, and pick him up when he returns to the arterial.

Traps

  • Continuing after being made.
  • Tunnel vision on the subject vehicle and missing the meeting.
  • Reconstructing the log at day's end instead of in real time.

Key points

  • Reconnoiter before deployment.
  • Leapfrog and hand off to stay unseen.
  • Static coverage often beats a risky follow.
  • Break off when compromised and document why.
  • Log in real time with timestamps.
