What is the difference between grid and polar target locations?

• A. A grid gives a square/rectangular location via coordinates; polar uses bearing and range from a known point
• B. Grid uses bearing and range; polar uses coordinates
• C. Grid is for air; polar is for ground
• D. Grid is old; polar is new

Answer: (A)

Grid locations pinpoint a point on the map using square coordinates, giving a precise address on the map itself. Polar locations describe where something is by giving a bearing (direction) from a known reference point and a distance to the target. In practice, grid coordinates are a map-based address you read off the grid, while polar is a direction and distance from a specific point. You can convert between them if you know the reference point and the map’s scale, but the form of the information is different: grid is two numbers tied to the map’s grid system, polar is a bearing and range from a point.
