Sentry Droid

Basic security droids are in common use by corporations and militaries alike. Bipedal in shape, these robots will typically carry a pulse rifle and patrol a designated area. They have enough basic programming to challenge intruders, but only within set pre-programmed parameters. Some militaries use these droids as cannon-fodder and disposable infantry, and they are a common sight in occupied areas where curfews and other restrictions are enforced.
