The Turret Core is an Aperture Science Personality Construct who is a recurring character in the Harry101UK animated Youtube series Meet The Cores. For all intents and purposes they are the Artifical Intelligence of a Sentry Turret placed into the body of a core, with several adjustments to the body to allow for combat. As demonstrated in Episode 2 of Meet The Cores, the Turret Core is able to open up it's chassis to reveal a set of twin Gatling guns, making it far more deadly than a regular.
