A type of sight used on weapons that features a small, clear, screen (Usually about 2" x 2") with a holographic projection of a red dot or red cross, most comonly made by the company eotech. Reflex Sights usually mount on RIS rails, and assist in target acquisition in close combat situations.
The Ranger's Reflex sight allowed him to get a faster yet accurate shot across on the terrorist who was using an old fashioned Ironsight.
