Which reconnaissance task involves determining the concentration or amount of CBRN agent?

• A. Quantify
• B. Detect
• C. Identify
• D. Collect

Answer: (A)

The concept being tested is quantification: the ability to determine how much of a CBRN agent is present, not just whether it exists. In reconnaissance, this means obtaining a numeric measure of concentration or total amount, such as the agent’s concentration in the air (ppm or mg/m^3) or the level of surface contamination (mg/kg or similar units). This quantitative result is essential for assessing severity, exposure risk, and informing protective actions and remediation. Other tasks focus on different goals. Detecting answers the question of presence—is the agent there at all? Identify determines what the agent is—its exact chemical or biological identity. Collect involves gathering samples for later laboratory analysis. While all are important steps in a response, only quantification provides the actual amount or concentration measurement.
