On the AN/PVS-14 monocular night vision device (MNVD), what component enables the operator to see azimuth readings in the monocular?

The correct answer is the compass, as it provides the crucial capability for the operator to determine azimuth readings while using the AN/PVS-14 monocular night vision device. Azimuth readings are essential for navigation and orientation in the field, and the inclusion of a compass in the device allows the user to ascertain their direction relative to the magnetic North.

This functionality is particularly beneficial for military operations where situational awareness and accurate navigation can significantly impact mission success. The compass integrated into the device provides real-time directional information, allowing users to maintain orientation during low-visibility conditions enabled by night vision technology.

In contrast, while gyroscopes and accelerometers are important components for other navigation and stabilization tasks, they do not directly provide azimuth readings. A rangefinder is primarily used to measure distances and does not contribute to directional orientation in the same way as a compass does. Thus, the compass is the essential component for enabling azimuth readings in the monocular night vision device.
