Turret

Automated Turrets are automatic, unmanned machine guns which are capable of sensing and attacking targets that are hostile to the faction or organization to which they belong.

They are employed by both military organizations like the Enclave or Brotherhood of Steel, and civilian operations such as the Museum of History, though in the latter case their former operators have been long since gone. In one case, a Raider group near the Arlington Library has reprogrammed turrets to protect a camp and a drug lab.

Variants
Automated turrets can rest on the floor or hang from the ceiling. The ceiling turrets use bullet-based weaponry whereas the ground turrets are equipped with lasers. Both variants have unlimited ammo.

The following models exist: There are a few, stat-wise identical versions of each model in the game (with different Base IDs) for different factions.

Tactics

 * Turrets are generally controlled from a nearby terminal. Using your Science skill to hack the terminal will allow you to override the targeting parameters - which will make the turret target any character (not just the player) or shut it down completely. After being turned off the turret can be turned back on at the same terminal if so desired.
 * Shooting at the targeting module carries a high chance of the turret becoming frenzied, and attacking everyone. Any shot at the module also does increased damage.
 * The ceiling-based turrets have a blind spot directly below them, making it a key location for attack.
 * Some Enclave officers carry special keycards which can be stolen. Once stolen the turrets turn on them.

Appearance
Automated turrets can be found in many locations around the ruins of Washington, DC in Fallout 3, and in Alaska during Project Anchorage.
