What are the levels of MOPP?

• A. MOPP 1, 2, 3, 4, 5
• B. MOPP 0, 1, 2, 3, 4
• C. MOPP A, B, C, D
• D. MOPP X, Y, Z

Answer: (B)

The levels of MOPP, which stands for Mission Oriented Protective Posture, are correctly identified as MOPP 0, 1, 2, 3, and 4. This system is utilized by military personnel to provide a framework for how to don personal protective equipment (PPE) based on the threat level of chemical, biological, radiological, and nuclear (CBRN) hazards.

In MOPP 0, personnel are in a normal posture without any PPE on, indicating a low threat level. As the threat increases, the level of MOPP escalates, requiring the addition of protective gear. MOPP 1 involves having the protective mask readily available, MOPP 2 requires the uniform to be fully sealed, MOPP 3 adds in the use of additional protective gear such as gloves, and MOPP 4 represents the highest level of readiness where full protective clothing is worn at all times.

The other choices do not correctly reflect the established MOPP levels, as they either include nonexistent categories or use different designations that are not officially recognized in military protocol. Understanding the proper MOPP levels is crucial for operations in environments where there are potential CBRN threats, ensuring
