Made for the FBI Chicago’s Special Operations Group, this patch contains the term “Cave Dwellers” because the original office of the SOG was located in the basement of the FBI Field Office there and had no windows. Many of the agents said they felt like they were “stuck in a cave” Hence, they started to refer to themselves as “Cave Dwellers” and chose the Batman theme in reference to the Bat Cave.
