What is a recommended practice concerning supplemental lighting during night operations?

Using red or green lights during night operations is advisable because these colors are less disruptive to night vision. Human eyes are more sensitive to green light, which allows for better visibility while maintaining some level of night adaptation. Red light, on the other hand, is typically used because it helps preserve the eyes' sensitivity to darkness, making it easier for personnel to see in low-light conditions without losing their night vision.

This approach provides a balance between visibility and the ability to operate effectively in darkness, ensuring that eyes remain adapted to low-light environments. During night operations, maintaining optimal night vision is crucial for safety, stealth, and situational awareness, and using red or green supplemental lighting aligns with these needs. This practice enhances operational effectiveness while minimizing the risk of being detected by others.
