The NBCI operates from the Dublin Metropolitan Region (DMR) Headquarters of the Gardaí in Harcourt St, Dublin 2. NBCI officers are mostly experienced detectives, who have been promoted to the unit from other investigative units, and the majority have spent time as local/regional detectives. All officers within the NBCI are armed. The unit receives funding for specialist equipment (such as investigative tools, weapons and vehicles) which other areas of the force does not possess, and therefore more serious crimes and crimes of a sensitive nature are investigated by the NBCI.
