Argentine Army Aviation The Argentine Army Aviation ( Spanish : Comando de Aviación Ejército Argentino , AvEjer ) is the army aviation branch of the Argentine Army . Their members have the same rank insignia and titles as the rest of the Army . Along with its primary role of supporting Army operations , the Army Aviation is highly involved in humanitarian aid missions , emergency relief , medical evacuations and forest firefighting . Army aircraft with tactical camouflage have adopted high - visibility yellow markings " Ejército " ( Spanish for " Army " ) in order to encourage the national press to stop referring to them as belonging to the air force . History . Military aviation in Argentina traces back to the Paraguayan War when on 8 July 1867 , Staff Sargeant Roberto A . Chodasiewicz used an Observation balloon during the battle of Humaitá . Since then , the army was the main driving force behind national aeronautical development . The use of enthusiastic students who relied on the selfless support of civil institutions and airclubs , saw the creation of the Military Aviation School at El Palomar in 1912 . The establishment of the Army Aviation Service saw a great expansion of Argentine air power in the 1912 – 1945 period . The creation of the first aviation units and foundation of Fabrica Militar de Aviones lead to the creation of the Argentine Air Force in 1945 , which the Army had given most of its aircraft and installations . The Army retained a number of Cessna and SNJ - 4 aircraft for observation and training purposes . Army SNJ aircraft attacked government troops in Buenes Aires during the 1955 Revolución Libertadora , one of which was lost to an Argentine Air Force Gloster Meteor . In 1956 , Army Aviation was re - established within the Army and began a major expansion , incorporating new types of aircraft and opening new bases around the country . In 1965 , using a Cessna U - 17 they performed their first expedition to the South Pole . During the 1970s the service consolidated itself as an important branch of the Army receiving aircraft such as the Aeritalia G . 222 transport which caused no little differences with the Air Force . The expansion plans continued in early 1980s with the incorporation of the Boeing CH - 47 Chinook heavy - lift helicopter . The dictatorship that took power in 1976 increased tensions with Chile which reached their highest point during the 1978 Operation Soberanía where the Army Aviation performed major deployments . Falklands War . In 1982 , the " Military Junta " invaded the Falklands Islands ( ) triggering a ten - week long war against the United Kingdom . The Argentine Army Aviation deployed CH - 47 Chinook s , Agusta A109 , SA330 Puma s and UH - 1H s to the islands , where they performed 796 general support flights under harsh operating conditions . Their helicopters were also extensively used in Patagonia and the Army also took over police MBB Bo 105 s during the conflict . Six Army aviation members died in the war . Present Day . After the war , the Aerospatiale Super Puma was incorporated , mainly for Antarctica support duties operating from Navy ' s icebreaker ARA " Almirante Irizar " . In 1998 , Argentina was granted Major Non - NATO ally status by United States President Bill Clinton and the Army Aviation began an expansive program that included the reception of OV - 1 Mohawk s and surplus UH - 1H from the US Army . The US also authorized the delivery of 12 AH - 1F Cobra gunships but the operation was halted by the Argentine Government . In the 1990s , the Aviation Army began its Unmanned aerial vehicle program , the Lipan series . In 2007 , the Ministry of Defense evaluated the Chinese Changhe Z - 11 ( Argentine index AE - 350 ) and 40 are to be built . Also in 2007 , the Army unveiled the indigenous Cicaré CH - 14 Aguilucho scout prototype . A major update program is currently underway refitting the Hueys to the Huey II variant . On March 2010 it was announced the purchase of five Bell 206 for the Joint armed forces school Pilots training and recruitment . Argentine Army gets its pilots from two main sources . One are the officers graduated from the Military Academy , who volunteer for the Army Aviator Course . This course lasts one year and takes place at either the Air Force Academy , in Cordoba ( for fixed wing aircraft ) , or the Army Aviation School ( for helicopters ) , in Campo de Mayo , outside Buenos Aires . Since 2009 , these two schools are the only training center for pilots from the three Armed Services . The other source are civilian pilots who , after a ten month course at the Military Academy , join the Army Aviation as 2nd lieutenants . While Academy - graduated officers are called " Army Aviators " and those coming from civilian life are " Army Pilots " , there ' s no specific technical differences between them . However , " Army Pilots " can only reach the rank of colonel . Also , " Army Aviators " retain their original branch ( i . e . Infantry , Cavalry , Artillery , Engineers , Signals or Ordnance ) and can be posted to their branch ' s units in case of need . " Army Pilots " , instead , can only serve in Army Aviation units or related positions , as they have no other capability . Structure / Air bases . The main airbase is located at Campo de Mayo where all the training and maintenance is done The service has also permanent forward location bases assigned to both division and brigade HQ levels . Aircraft inventory . In addition to army aviation , a small air fleet is maintained by the border guard Gendarmeria Nacional Argentina . References .
