Which single fuzing type is listed as applicable across several activation types (blast, heat, and chemical)?

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

Answer: (C)

Activation scenarios like blast, heat, and chemical processes all create measurable pressure changes. A pressure fuze is designed to respond to those pressure increases, so it can be triggered by a blast wave, by the pressure from heat-induced gas expansion, or by gas generated during a chemical reaction. That versatility—responding to pressure changes across different activation types—makes it the best choice for being listed as applicable across several activation methods. Tilt-rod fuzes depend on physical orientation and tilt, not pressure from environmental conditions. Pull fuzes require a deliberate manual action, so they aren’t inherently tied to blast, heat, or chemical triggers. Command-detonation fuzes are activated remotely by an electrical command rather than by the surrounding conditions themselves.
