A reticle is an icon, focused at infinity in a pilots Heads-up Display showing the predicted path of a missile, bomb or gunfire. When you lock on to a target, most show a large, red icon with range, roll, and steering information to your target. F-4G Wild Weasels added a green reticle, showing any threatening surface-to-air transmitter sites. When the red and green reticles match up, a dumb bomb release would destroy the transmitter.
