How does Shift From Known Point locate a target?

How does Shift From Known Point locate a target?

• A. The observer uses a known point near the target and provides directional and distance offsets; the FDC computes the target position from the offsets.
• B. The observer sends an approximate target location and the FDC estimates.
• C. The observer uses a photograph to identify the target location.
• D. The target location is assumed from recent activity.

Answer: (A)

Shift From Known Point uses a reference point near the target to locate it. The observer identifies a known point that both the observer and the FDC can pinpoint on the map and in the field. From that point, the observer provides two offsets: a direction toward the target and a distance from the known point to the target. The FDC then uses the exact coordinates of the known point and applies those offsets to compute the target’s position on the map. This method works well because it doesn’t require the target’s exact location to be named or observed directly; instead, you anchor it to a familiar point and move along the specified direction and distance to pinpoint where the target lies. Other approaches that rely on approximate, photographic, or activity-based indications aren’t as reliable for precise plotting, whereas shifting from a known point gives a clear, computable location.
