Place a minimum of ___ markers ___ to _____ meters apart.

• A. minimum of 3 markers 10 to 100 meters apart
• B. minimum of 2 markers 5 to 50 meters apart
• C. minimum of 4 markers 20 to 60 meters apart
• D. minimum of 5 markers 100 to 200 meters apart

Answer: (A)

Setting markers along a reconnaissance route requires enough points to define the line and provide a reliable backup. Using a minimum of three markers creates a simple sequence you can follow and verify—the start, a middle point, and an end point help ensure you’ve connected the route correctly and reduce the chance of losing the trail if one marker is disturbed.

Spacing those markers 10 to 100 meters apart balances visibility with efficiency. If markers are placed too close, you waste resources and clutter the area; if they’re too far apart, someone could miss the next marker, especially in rough terrain or dense cover. Ten meters keeps markers easily spotted from the previous one, while a hundred meters ensures you cover a useful distance without sacrificing detectability.

Other options either require too many or too few markers, or specify distance ranges that fall outside practical visibility in typical field conditions. The minimum three markers with the 10 to 100 meter spacing best fits reliable route marking with reasonable effort.
