These were mostly established by the United States in the several countries it had protective status over (e.g. Philippine Constabulary , United States Constabulary in West Germany after World War Two, Nicaraguan National Guard , Panama National Guard). These forces also performed military functions by maintaining "mobile forces" of organised units. In Europe such forces are called Gendarmerie s or (in Italy ) Carabinieri .
