Sentry bots come in many different guises, distinguishable by their paint, which shows their affiliation: Enclave, Brotherhood Outcasts, United States Armed Forces.

U.S. Army
They can be encountered at Fort Constantine, the National Guard depot and occasionally wandering around the Wasteland.

Presidential metro Sentinal Unit
This unique sentry bot is encountered in Broken Steel at the end of the Presidential metro, near the metro to the Adams Air Force Base. It possesses the main fuse, which is needed to repair the nearby powerbox for the metro.
