Red filter:  
The Red filter is great for penetrating fog and smoke, and ideal for signaling. Red is also ideal when you want to preserve your night vision. Hunters use the red filter to avoid disturbing animals during pre-dawn hours -- animals see poorly in the red color spectrum. The filter is also useful for close range, non-tactical applications -- such as map reading -- as it reduces the intensity of light output. 

For military operations; a red beam will always light the path ahead without jeopardizing night vision or strategic position. A red beam also perfectly illuminates star maps & lenses without affecting night vision. It won't attract insects.
