Which of the following is NOT a level of decontamination?

• A. Initial
• B. Thorough
• C. Operational
• D. Immediate

Answer: (A)

Decontamination in military operations is categorized into three formal levels: Immediate decontamination at the point of exposure to quickly remove contamination from skin and gear; Operational decontamination conducted as personnel and equipment move through contaminated areas to reduce contamination to safe levels for movement and mission continuity; and Thorough decontamination as a complete, controlled process at a dedicated facility to remove residual contamination from people and equipment. The term you’re asking about isn’t part of this official framework; it describes an early action rather than a defined level. So, Initial isn’t a recognized decontamination level, while Immediate, Operational, and Thorough are.
