Sentry gun
From Wikipedia, the free encyclopedia
A sentry gun is a gun that is automatically aimed and fired at targets that are detected by sensors. The earliest functioning sentry gun was the Phalanx CIWS, a radar-guided gatling gun platform that defended ships from missiles. In 2006, Samsung Group announced a 5.56 mm robot machine gun to guard the Korean DMZ (Samsung SGR-A1).

[edit] Military use
The earliest functioning sentry gun was the Phalanx close-in weapons system (CIWS), a radar-guided gatling gun platform that defends ships from missiles. There is a land-based version of the Phalanx CIWS, also used for missile defense. Similar to the Phalanx is the Goalkeeper CIWS, a more powerful version with the same purpose. According to the United States Navy:
Phalanx is the only deployed close-in weapon system capable of autonomously performing its own search, detect, evaluation, track, engage and kill assessment functions[1]
These guns perform sentry duty against missiles, but are not in line with the fictional versions of the sentry gun that are used primarily against humans in books, movies, and video games.
[edit] In Popular Culture
In Infinity Ward's popular game, Modern Warfare 2 you are able to recieve a Sentry Gun from an aerial drop, and it will kill anything within a 180 degree radius. It was depicted as a rather small and easily disabled mobile version of a Sentry Gun in the game.
Sentry guns are also featured in the video game Team Fortress 2, as objects which can be built and upgraded by the Engineer class.
