At what MOPP level is General Quarters (GQ) activated?

General Quarters (GQ) is activated at MOPP level 3. At this level, personnel are prepared to respond to a chemical, biological, or radiological (CBR) threat and are equipped with the necessary protective gear, including masks and overgarments. The activation of GQ indicates that the situation is escalating to a point where heightened readiness is essential.

At MOPP level 3, while personnel are not completely sealed within their protective equipment, they must be prepared to don masks quickly and are required to remain vigilant. This level of readiness ensures that the crew can effectively combat threats while maintaining operational effectiveness. MOPP levels 1 and 2 do not involve the same degree of readiness required for GQ activation, as they focus more on initial assessments and precautionary measures rather than immediate action in a heightened alert status. MOPP level 4 requires complete protective gear and is typically used in more extreme situations after GQ has already been established.
