Sentry Bot (Fallout 3)

These Sentry Bots are 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 and a missile launcher), and three legs that end with wheels. The sentrybot is well armored and is capable of taking more than one direct rocket without being destroyed. One quick way to get past these metal hulks is to throw a pulse grenade at them which temporarily disables the robot. With this window of opportuinity, unload on the robot without fear of reprisal.
