What precaution should be taken when using night vision goggles during combat?

Using night vision goggles in combat scenarios presents several challenges and hazards, and understanding their limitations is critical for ensuring the safety and effectiveness of the user. Avoiding the use of night vision goggles in laser-prone areas is particularly important because lasers can permanently damage the sensors inside the goggles, rendering them useless and potentially impairing the user's vision.

When these goggles are exposed to high-intensity lasers, the bright light can overload the intensifier tubes and cause a phenomenon known as "blooming," where the image becomes distorted and unusable. In extreme cases, exposure can cause irreversible damage, which is why all personnel using night vision devices must be aware of their surroundings and the potential presence of lasers.

Each of the other options, while relevant in a broader context of safety and operational preparedness, do not directly address the critical risk associated with laser use. It's important for combat medics and other personnel utilizing night vision equipment to be trained and informed about the specific risks posed by lasers to maximize both their effectiveness and safety during operations.
