 In case of war, the "Guarda Fiscal" would pass for the authority of the Portuguese Armed Forces, forming combat units that would be used primarily in the border defense.The "Guarda Fiscal" was formed on September 17, 1885, based on the Barrier Guards detached from the former Royal Guard of the Police (ancestor of the present National Republican Guard) for the tax and customs service.In 1993, the "Guarda Fiscal" was dissolved as an independent corps, becoming the Fiscal Brigade of the National Republican Guard (GNR).
