Which target location method uses a known point as a reference and then shifts?

• A. Shift from Known Point
• B. Grid
• C. Polar
• D. Elevation Only

Answer: (A)

Shift from Known Point centers on anchoring the target location to a reference feature whose position you already know, then applying a measured offset to reach the target. You identify a known point on the map, confirm its coordinates, and from there move by a specified shift—an offset in direction and distance (or grid offsets)—to place the target. This approach is ideal when the target isn’t easily observed from your position, so you rely on a nearby known point and a defined shift to determine where the target lies. The other methods don’t describe this exact process: grid uses direct grid coordinates, polar uses a bearing and range from a known point to triangulate, and elevation only relies on vertical angle information without applying a shift from a reference point.
