During each leg of the survey pattern, dismounted reconnaissance personnel should detect CBRN hazards at ________ to ________ meter intervals.

The interval of 100 to 200 meters for detecting CBRN hazards during dismounted reconnaissance is based on the effectiveness of detection devices and safety considerations. This range allows personnel to maintain a safe distance while ensuring comprehensive coverage of the area being surveyed.

At 100 meters, personnel can effectively utilize their detection sensors to identify potential hazards while minimizing the risk of exposure to harmful agents. Extending the interval to 200 meters provides an additional buffer, allowing them to capture data from a wider area without jeopardizing their safety. This balance is critical in CBRN operations where threats can be pervasive and safety is paramount.

The wider range also facilitates a more thorough assessment of the environment, increasing the likelihood of detecting low-concentration agents or substances that might not be immediately apparent.
