Remember these? Introduced originally in the Vietnam days, this is a lighter replica of the original US Military Issued MX991s that comes with 5 Lens Filters - one clear filter installed and a blue, orange, green and red filter included in the base.
This was the classic military flashlight used in Vietnam, and has since been labeled as one of the most "war-like" flashlights in the U.S. Military. Take note, the red and blue lights preserve night vision and the blue is less visible to night vision devices that work near infrared. Also, it can help to ID friendlies...trust us, we know.
