The color red helps to preserve a persons 'night vision'. If white light were used and a soldier heard something and tried to look out into the darkness, he couldn't see much.
true but not totally true. red still makes most colors visible to the eye more-so than other colors and it has the least amount of ambient light so the soldier cant be detected while reading a map by the light reflecting off of it. red also doesnt travel as far of a distance than other colors so the enemy cant see it far away or even fairly close up. finally red is just the best color to use at night because you can still see ahead of you (not far) but someone else wouldn't see the light unless they accually saw the bulb itself, the ambient light (excess light emitted which is unused and not in the focused beam) cant be seen at all at night over a certain distance too.
hoped that helps
Are you referring to the colour of the flashlight bodies? They're olive drab to match the webbing which is worn, as the flashlights might be worn externally on the webbing. The colour itself is designed to blend in with vegetation... a shiny silver flashlight would reflect light and might compromise personnel in a tactical situation.
Flashlights exist so you can have a portable light source. You can use flashlights where there are no other types of lights. You can use them in emergencies, and you can use them in places where other types of lights would be awkward or hazardous.
People use flashlights when they are in need of a light source. If the power goes out at night, the use of a flashlight is essential to get around the house. Flashlights can also be used in emergency situations outside of the house.
They can.

LED bulbs tend to be very bright and use far less power to operate making them perfect for flashlights. Halogen bulbs are also very bright and used in flashlights.
Candles, torches etc

Streamlight flashlights are made for public safety officers such as firefighters, police officers and military personnel. They are brighter than a conventional flashlight and can cut through smoke, helping a firefighter to see in a burning building.

LED flashlights are effective. They use powerful white-light-emitting diodes, and are more efficient than incandescent lamps, in terms of battery usage.
