Division 14, also known as D-14, was a specialized Starfleet division that handled mysterious science- or medical-related problems afflicting its personnel.
Division 14 maintained a spa on Endicronimas V known as "The Farm" to give the best care possible to its patients. The Osler was used to transport patients to the facility.
In 2380, following a transporter accident that rendered him out of phase, Ensign Brad Boimler of the USS Cerritos was to receive treatment from this division. Once he arrived on Endicronimas V, however, his condition resolved itself, without requiring any treatment. (LD: "Much Ado About Boimler")
