What is NOT one of the four types of patrol techniques?

The correct option highlights that "Regular" is not considered one of the four types of patrol techniques. Patrol techniques are designed to ensure effective monitoring and response to various situations, and they typically include fixed, conspicuous, and irregular methods.

Fixed patrols involve stationary monitoring of a specific area, allowing for a focused observation of that location. Conspicuous patrols refer to measures taken to be visible to deter potential criminal activity, thereby enhancing safety through visibility. Irregular patrols indicate a non-structured, variable approach to monitoring that can adapt to different circumstances or unpredictability in a situation.

Regular, however, implies a consistent, unchanging method that lacks the adaptability and dynamic nature of the recognized types of patrol techniques. The use of the term "Regular" may falsely suggest a systematic approach, but it does not fit within the established categories used in security practices. Understanding the specific definitions of these techniques helps security personnel effectively manage and interact with the environment they are tasked to protect.
