Gendarmerie A gendarmerie or gendarmery ( or ) is in principle a military force charged with police duties among civilian populations . Members of such a force are typically called " gendarmes " . These units are also associated with other descriptions , such as " maréchaussée " ( marshalry ) or Guard or Constabulary . The Shorter Oxford English Dictionary describes gendarme as " a soldier who is employed on police duties " and a " gendarmery , - erie " as " gendarmes as a body " . Sometimes forces that are no longer military still use the title for historic reasons , in the same manner as many other units use obsolete military titles ( cf . " hussar s " , " cuirassier s " etc . ) but these are not strictly gendarmeries . The system of militarily organized police departments enlarged upon Europe since the Napoleonic era as well as in many former French colonies and mandated territories . Etymology . The word " gendarme " comes from Old French " gens d ' armes " , meaning men - at - arms . Historically , during the Late Medieval to the Early Modern period , the term referred to a heavily armoured cavalryman of noble birth , primarily serving in the French army ( see Gendarme ( historical ) ) . The word gained policing connotations only after the French Revolution when the Maréchaussée of the Ancien Régime was renamed the Gendarmerie . In the United Kingdom , there is a body called Her Majesty ' s Bodyguard of the Honourable Corps of Gentlemen at Arms . " Gentlemen at Arms " is a near etymological equivalent to the term " gendarme " . This body , however , is purely ceremonial and is not considered a gendarmerie . Historically the spelling in English is " gendarmery " , but the French spelling " gendarmerie " is now more common . The Oxford English Dictionary ( OED ) still uses " gendarmery " as the principal spelling while Merriam - Webster uses " gendarmerie " as the principal spelling . Title and status . These forces are normally titled “ gendarmerie ” , but gendarmeries may bear other titles , for instance the " Carabinieri " in Italy , the " Guarda Nacional Republicana " in Portugal or the " Guardia Civil " in Spain . As a result of their duties within the civilian population , gendarmeries are sometimes described as " para - military " rather than " military " forces ( especially in the English - speaking world where policing is rarely associated with military forces ) although this description rarely corresponds to their official status and capabilities . Gendarmes are often deployed in military situations , sometimes in their own country , and often in humanitarian deployments abroad . A gendarmerie may come under the authority of a ministry of defence ( " e . g . " , Italy ) , a ministry of the interior ( " e . g . " , Romania ) , or even both at once ( " e . g . " Chile , France , Spain and Portugal ) . Generally there is some coordination between a ministry of defence and a ministry of the interior over the use of gendarmes . Some forces which are no longer considered military retain the title “ gendarmerie ” for reasons of tradition . For instance , the French language title of the Royal Canadian Mounted Police is " Gendarmerie royale du Canada " ( GRC ) ( " i . e . " , Royal Gendarmerie of Canada ) because it was traditionally a military force ( although separate from the Canadian Army ) and because until the 1960s it retained an honorific status as a regiment of dragoons . The Argentine Gendarmerie is a military force ( in terms of training , identity and public perception , and it was involved in combat in the Falklands War ) , but for legal purposes is a " security force " , not an " armed force " , because this is necessary under Argentine law in order to allow jurisdiction over the civilian population . Since every country uses institutional terms such as “ gendarmerie ” as it wishes , there are cases in which the term may become confusing . For instance , in the French - speaking Cantons of Switzerland the “ gendarmeries ” are the uniformed civil police ( see : Gendarmerie ( Switzerland ) ) . In Chile , the word “ gendarmerie ” refers for historic reasons to the prison service ( the " Chilean Gendarmerie " ) , while the actual gendarmerie force is called the " carabineros " . In some cases , a police service ' s military links are ambiguous and it can be unclear whether a force should be defined as a gendarmerie or not ( e . g . Mexico ' s Federal Police , Brazil ' s Military Police , or the former South African Police until 1994 ) . Services such as the Italian Guardia di Finanza would rarely be defined as gendarmeries since the service is both of ambiguous military status and does not have general policing duties in the civilian population . In Russia , the Internal Troops are military units with quasi - police duties . Role and services . In comparison to civilian police forces , gendarmeries may provide a more disciplined force whose military capabilities ( " e . g . " , armored group in France with armored personnel carriers ) make them more capable of dealing with armed groups and with all types of violence . On the other hand , the necessity of a more stringent selection process for military service , especially in terms of physical prowess and health , restricts the pool of potential recruits in comparison to those a civilian police force could select from . In countries where the gendarmerie and civilian police co - exist there may be rivalries and tensions between the forces . This was one of the reasons cited for the decision to disband the Belgian Gendarmerie , absorbing its functions into those of a new national police force . In France , the gendarmerie 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 . French influence . The use of military organisations to police civilian populations is common to many time periods and cultures . Although it cannot be considered a French concept , the French gendarmerie has been the most influential model of such an organisation . Many countries that were once under French influence have a gendarmerie . For instance , Belgium , Luxembourg and Austria had gendarmeries through Napoleonic influence , but all these gendarmeries have merged with the civil police , in 2001 , 2002 and 2005 respectively . Many former French colonies , especially in Africa , also have gendarmeries . A common gendarmerie symbol is a flaming grenade , which was first used as a gendarmerie symbol by the French . Role in modern conflicts . Gendarmes play an important role re - establishing law and order in conflict areas , a task which is suited to their purpose , training and capabilities . Gendarmeries are widely used in peacekeeping operations , for instance in the former Yugoslavia , in Ivory Coast , sometimes via the European Gendarmerie Force . Gendarmerie forces .
