The GNR (Guarda Nacional Republicana) is Portugal's national gendarmerie—a military police force founded in 1911, with origins dating to 1801. With over 22,600 personnel, GNR patrols 94-96% of Portuguese territory, covering rural areas, medium towns, and highways. Members are military personnel subject to military law, responsible for public order, customs, coastal control, environmental protection (SEPNA), firefighting/rescue (GIPS), border control, and ceremonial guards. ​ GNR vs. PSP: The PSP (Polícia de Segurança Pública) is Portugal's civilian police force, covering major cities (Lisbon, Porto, Faro) and large urban areas—only 4% of territory but roughly half the population. PSP handles airport security, diplomatic protection, and private security regulation. Both share core missions (public order, crime prevention), but differ in nature: GNR is military with military training; PSP is civilian with police-focused training.
