You should place the markers to a desired height that permits approaching military forces to view the markers at distances up to how many meters?

• A. 500 meters
• B. 200 meters
• C. 50 meters
• D. 100 meters

Answer: (B)

Understanding visibility distance comes down to line of sight. When a marker is raised, it sits higher above the ground and can be seen from farther away before terrain or obstacles block the view. In many field-training standards, a height that allows viewing up to about two hundred meters provides a practical balance: it gives enough early notice for approaching forces to spot the marker without making it so far that it becomes unreliable to discern under typical daylight conditions or terrain. If the marker were only visible at very short ranges, like fifty meters, there would be little warning or time for decision-making. Pushing the range to five hundred meters can be unreliable because terrain, weather, and the marker’s size and contrast affect visibility, and it increases the chance that the marker is detected by others sooner than intended. So, the distance up to two hundred meters is the best fit for ensuring visibility while maintaining reasonable operational considerations.
