Which of the following increases the effectiveness of NVGs in the field?

Regular maintenance and adjustments significantly enhance the effectiveness of night vision goggles (NVGs) in the field. NVGs require fine-tuning to ensure optimal performance, including alignment of optics and calibration of the intensifier tube. Dust, dirt, or any damage can lead to reduced image clarity or even malfunction during critical missions. Consistent upkeep helps users maintain a clear and sharp field of view, ensuring that the device operates as intended under various environmental conditions, which is essential for tactical operations.

While using NVGs in absolute darkness might seem beneficial, these devices rely on ambient light, such as moonlight or starlight, and absolute darkness can limit their effectiveness. Pairing NVGs with advanced combat gear can enhance operational capability, but does not directly improve the function of the NVGs themselves. Relying solely on audio cues can be a tactic used in conjunction with NVGs, but it doesn’t contribute to the performance of the goggles.
