For landmines activated by heat, which two fuzing types are listed?

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

Answer: (A)

The key idea is understanding how fuzes are activated in mines and which types are associated with heat-activated designs. For mines described as activated by heat, the fuzing options listed include a mechanical tilt-rod sensor and an electronic/influence sensor. The tilt-rod type responds to a change in orientation or disturbance of the mine, while an influence fuze uses sensors to detect environmental changes such as heat signatures before initiating. The other options represent different initiation methods—pressure fuzes respond to weight on a surface, pull fuzes use a tripwire, and command detonators require a remote signal—and are not the heat-activated types described in this context. Thus, tilt-rod and influence are the two fuzing types listed for heat-activated mines.
