What are the 5 levels of MOPP?

• A. 0: no threat; 1: suspected threat; 2: possible threat; 3: probably threat; 4: imminent threat
• B. 0: no threat; 1: possible threat; 2: probable threat; 3: definite threat; 4: extreme threat
• C. 0: safe; 1: alert; 2: caution; 3: danger; 4: extreme danger
• D. 1: no threat; 2: mild threat; 3: moderate threat; 4: severe threat; 5: catastrophic threat

Answer: (A)

The idea being tested is how a threat level is mapped to protective posture. This set of levels uses a clear, progressive scale from no threat up to imminent threat, which is exactly how protective actions are escalated in a CBRN context. The best choice presents: 0 means no threat, 1 means suspected threat, 2 means possible threat, 3 means probable threat, and 4 means imminent threat. That sequence provides a logical rise in concern that guides when and how to increase readiness and protective measures. The other options mix in descriptors that aren’t consistent with how this five-step scale is used, such as nonstandard terms or starting points that don’t fit a linear progression from no threat to imminent threat. This makes them less accurate for describing how MOPP-related decisions are driven by threat credibility.
