Chile has the world’s third-longest border, at 6,339 kilometers, which is primarily flanked by the Cordillera de los Andes, which has a mean elevation of 4,000 meters and a maximum elevation of 6,800 meters. As a result, accessing the edges of Chile is generally difficult. For instance, border control is difficult, and the deployment and/or preparation of army personnel to this environment requires a thorough understanding of the human body under these extremely harsh conditions.
