 * The United States Southern Command (USSOUTHCOM), built a "Humanitarian Relief Base" at the Resistencia Airport in Chaco Province, since 2012. According to USA "The USSC is responsible for providing contingency planning, operations, and security for Central America, South America and the Caribbean. It is a joint command comprised of more than 1,200 military and civilian personnel. Its mandate is to operate a Humanitarian and Disaster Relief programme, which develops civilian infrastructure necessary for economic and social reforms aimed at improving the living conditions of impoverished regions."
 * According to USA officials "there is no deployment of any US civilian or military personnel and no connection with the development or operation of the facility by US personnel. It is entirely Argentine," and "the centre consists of only one permanent structure to be manned by 75 staff."
 * To the USA goverment "The major area of concern is what the US has described as the spread of Hezbollah and narco-terrorism in the region. They have equated this with increasing Iranian activity in the area." So this base allows for optimal potential intervention/observation abilities in the Triple Border Area.
