When additional accuracy is required, the observer should obtain an 8 digit grid target location.

• A. 6 digit grid
• B. 8 digit grid
• C. 4 digit grid
• D. 12 digit grid

Answer: (B)

Increasing grid precision increases how tightly you pin a target on the map. A four-digit grid places the target within a 1,000-meter square. Adding two more digits narrows that to a 100-meter square, and adding two more digits (for an eight-digit grid) narrows it further to about a 10-meter square. When you need greater accuracy, you use that eight-digit grid because it gives you roughly ten-meter precision, which is much more precise than the 100-meter or 1,000-meter levels. Using fewer digits is coarser and less exact, while more digits than eight are beyond the standard requirement in many FO scenarios, though they can be used in specialized cases.
