Protecting Argentina’s 9,300-kilometer border with Chile, Bolivia, Paraguay, Brazil and Uruguay requires significant attention from the Gendarmería Nacional Argentina (GNA), the country's 70,000-person border guard force located in the capital city of Buenos Aires. The GNA, as well as their border force colleagues in neighboring countries, must also grapple with cross-border crime that take advantage of the close ties among the region’s economies. According to Interpol, illicit markets in these border regions may be worth tens of billions of dollars.
