For landmines activated by chemical means, which fuzing type is listed?

• A. Tilt rod
• B. Influence
• C. Cmd Det
• D. Pressure

Answer: (D)

The key idea is how landmine fuzes are triggered. Fuzes are designed to respond to a specific stimulus: mechanical pressure, tilt/motion, proximity/electrical influence, or remote command. When a mine is said to be activated by chemical means, the triggering mechanism is still a physical response rather than remote or purely electrical sensing. Among the options, a pressure fuze best matches this idea because it actuates the detonation when a certain load or force is applied to the mine, which can be the result of a chemical reaction inside or around the fuze that translates into a pressure change. Tilt rod and pressure are both mechanical, but tilt rod relies on angular movement, not chemical action. Influence fuzes detect changes in magnetic or electric fields, and command detonators are remotely triggered. Therefore, pressure is the most appropriate fuzing type associated with chemical-activation concepts.
