In a method of patrolling, the patrols radiate outward from the patrol base on a specific bearing for a specific distance, all turn in the same direction at right angles to the outward route and move for a specific distance, then turn again at right angles in the direction of the point of origin and return to the point of origin. Which is this method of patrolling ?

The Fan Method is a tactical reconnaissance patrolling technique used to systematically clear or scout an area around a central location, such as an Objective Rally Point (ORP) or a patrol base. According to standard military and paramilitary tactical manuals:

• Small patrols radiate outward from the base on specific bearings (azimuths).
• Upon reaching a certain distance, they turn 90 degrees (a right angle) and move for a specified distance to cover the lateral terrain.
• They then turn 90 degrees again to return directly to the point of origin.

This pattern ensures that the area is covered in overlapping, fan-shaped sectors, providing thorough reconnaissance. Other methods like the Box Method involve a single rectangular route, while Converging Routes involve multiple patrols meeting at a single forward point. The description provided in the question specifically defines the geometry of the Fan Method.
