Which option lists all four CBRN passive defense elements?

• A. Shape, Sense, Shield
• B. Shape, Sense, Shield, Sustain
• C. Shape, Sense, Shield, Sustain, Reconnaissance
• D. Shape, Shield, Sustain, Detect

Answer: (B)

In passive defense against CBRN threats, four elements define the essential protective posture: Shape, Sense, Shield, and Sustain. Shape means arranging the environment to reduce exposure and vulnerability—planning layouts, enforcing access control, and dispersing personnel and assets to limit how contamination can affect the force. Sense is the ability to detect and monitor CBRN activity early—using detectors, indicators, patrols, and warning systems so you know when and where a threat is present. Shield covers the protective measures that physically barrier or reduce the dose to people and equipment—shelters, filtration and air protection, personal protective equipment, and decontamination capabilities. Sustain focuses on keeping operations going and recovering after exposure—logistics, medical support, decontamination, and replenishment of supplies to maintain readiness. This four-element set matches the recognized framework, so it’s the best fit. Other options either omit one of these elements, add something not part of the standard passive-defense list (like Reconnaissance), or use a different term (such as Detect) that doesn’t align with the established wording.
