An N5 sentry droid functioned in the Karthon Chop Fields, a junkyard where New Republic prisoners were mandated to work, serving the New Republic. In approximately 9 ABY, the N5 sentry droid came up to Migs Mayfeld, a prisoner, while he was working, and commanded him to salute because New Republic Marshal Cara Dune was present. Dune took custody of Mayfeld, and the security droid agreed, telling the prisoner to go with her. Mayfeld didn't understand what was happening, so the droid repeated the command, and warned him that he had to comply within three seconds. The prisoner gave in, and went with Dune to her starship.
The N5 sentry droid showed up in "Chapter 15: The Believer," the seventh episode of The Mandalorian's second season, a television show that was made available on December 11, 2020 on Disney+. Donald Mills played the droid.
