Sentry Bot (Fallout 3)

The sentry bot (military serial numbers SB-XXXX) is a military robot model made before the Great War. A different sentry bot model was used in military bases in California, while this one has been seen mainly in the Capital Wasteland. They have two arms that end with deadly weapons (a minigun or Gatling laser on the right arm, and a missile launcher on the left arm), and tripod legs with wheels.

They are programmed with an authoritative, professional military personality, in contrast to the "gung-ho" personality of the Mr. Gutsy model.

Sentry bots are the highest level robot NPCs in Fallout 3, and are much more powerful opponents than protectrons, robobrains, and Mr. Gutsy models.

Statistics
Sentry bots are extremely durable, possessing as much health as a deathclaw and greater damage resistance, in that unlike a deathclaw they do not have a "weak point" that can be targeted for additional damage. In fact, their heads are actually more durable than their torsos. Like all other robots, sentry bots are equipped with a combat inhibitor, and will go into a frenzy if it is disabled. This can be helpful in dispatching other enemies, since the sentry bots are among the most powerful foes in the game. Despite its seeming bulk, the sentry bot is unusually fast, but has a very slow turning rate which can be exploited.

Bugs

 * The unique "Presidential Metro sentinal unit" has a misspelled name, as it is supposed to be "sentinel" instead of "sentinal"
 * Occasionally when the Robotics Expert perk is used to shut down a sentry bot, it will glitch and repeatedly play the shut down and power up animations forever, though still be disabled and not move, attack the player, or appear as a mark on the compass.

Quotes
Sentry bots possess an authoritative array of speech programming, mainly expressing its current programming out loud, much like the protectron. However, sentry bots have a "deeper" voice, instilling fear in all.


 * "Warning. Non-combatants are advised to leave the area. Security sweep in progress."
 * "Alert. Hostile detected. Lethal force authorized for all units."
 * "Do not interfere with security operations."
 * "Have a nice day."
