In France, the gendarmerie is in charge of rural areas and small towns (typically less than 10,000 inhabitants) which represent 95% of the territory and close to 50% of the population. Besides its territorial organization, it has crowd and riot control units (the "Gendarmerie Mobile", along with some corresponding units in the civilian police), counter-terrorism and hostage rescue (GIGN, again along with some corresponding units in the civilian police), maritime surveillance, police at sea and coast guard ("Gendarmerie maritime"), control and security at airports and air traffic police ("Gendarmerie des transports aériens"), official buildings guard, honorary services and protection of the President ("Garde Républicaine"), mountain rescue ("Peloton de Gendarmerie de Haute Montagne") and security of nuclear weapons sites.
