Which form of survey has the R&S element moving along a line that is orientate 45 degrees from the start line?

• A. Zig Zag
• B. Star
• C. Box
• D. Boundary

Answer: (A)

In this type of survey, the arrangement of movement patterns shapes how the reconnaissance and surveillance element sweeps the area relative to the starting line. A zig-zag pattern has the team move along back-and-forth legs that cross the start line at oblique angles, creating a diagonal sweep. That diagonal line of observation, typically around 45 degrees to the start line, lets you scan terrain on both sides as you advance, maximizing coverage and reducing blind spots.

Star, box, and boundary patterns organize movement and coverage differently: a star radiates outward from a center point, a box traces a rectangular perimeter, and a boundary follows the edge of the area. None of these configurations establish a single observation line consistently oriented at 45 degrees to the start line in the same way as a zig-zag pattern, which is why zig-zag is the best fit for the described orientation.
