Helmet-Mounted Sight

A Helmet-Mounted Sight is a new Defictionalization. It is essentially a Heads Up Display that tells your fighter/chopper where you want the bullets or missiles to go. It has also been upgraded to show what friendly fighters are equipped with to provide Stat-O-Vision.

Examples of Helmet-Mounted Sight include:

Anime and Manga

The prototype VF-0 Valkyrie in Macross Zero does it one better: the helmet tracks the pilot's eyeballs in order to acquire targets for the mecha's head-mounted cannons. Presumably, this became a standard feature, but this is one of only two times we actually see how it works.
- The other time it appears on screen is a blink and you'll miss it moment with Ozma in Macross Frontier.

Deadshot, a Batman villain and a member of the Suicide Squad and the Secret Six has one of these.

Predator. The title creature's shoulder cannon moves in synch with its helmet.
- In Alien vs. Predator: Requiem, the Predator installs a second plasmacaster on the other shoulder, although both are controlled by the same sight.
Blue Thunder. The direction of the title helicopter's autocannon is controlled by its pilot's helmet.
Nicholas Cage's character in Fire Birds, a rookie Apache pilot, has trouble learning to use one of these, leading to some... innovative teaching methods on the part of his instructor.
In Half Past Dead, Steven Seagal's character explains to his friend (played by Ja Rule) how to operate a crashed helicopter's gun using the helmet. When the firefight breaks out, it comes in handy.

There was a third-party product for the NES which was a headset-mounted zapper gun.
Among the "aura" options in the costume designer for City of Heroes was a variety of targeting lasers emitted from devices worn on the head or face. If that's too outre, one of the details available for faces (that aren't inside helmets) is a targeting reticule that goes over one eye.
A VR game like this was at Segaworld in London's Trocadero c. 1999.

US helicopter gunships since the early 1980s have used the IHADSS system, which can not only aim a laser designator for the AGM114 laser-guided antitank missile, but also aim an autocannon in the powered turret under the helicopter's "chin"
First found on the MiG-29 "Fulcrum" and copied by the West after discovering how effective they were from ex-GDR examples of that plane, particularly in combination with the R-73/AA-11 heat-seeking missile.
- er, the Honeywell VTAS system entered service with the US Navy in the late 1970s
The F22 and F35 are/will be equipped with these. Several attack helicopters are equipped with them as well.
- Specifically these aircraft, along with several older U.S. fighters like the F-15, F-16, and F/A-18 will be made compatible with the new Joint Helmet-Mounted Cueing System, which when combined with the new AIM-9X model of the Sidewinder allows for some absolutely gratuitous stunts involving Roboteching.
