Why do ‘tactical’ flashlights use red lenses?

I’ve heard it was because red light waves don’t travel that far, but I can see the red light on an airplane wing that’s miles away.

I was adding to the other posters. A tactical flashlight is meant for situations where you want to see without being seen. It gives enough light for you to read a map by, but allows you to get closer to an opponent without him seeing you do it.
