of Guatemala's dismal human rights record. CIA support continued uninterrupted despite congressional constraints on military assistance to Guatemala. The full scale of these concealed programs remains largely unknown. Shortly after the Laugerud regime renounced aid in 1977, the CIA reportedly sent a large shipment of arms to Guatemala from Puerto Rico by way of a proprietary airline service the Flying Tiger - a sister organization of Air America. This shipment included machine guns, grenades, mortars and other lethal military supplies. 1980s In 1981 the new administration of Ronald Reagan approved a $2 million covert CIA program for Guatemala. A classified NSA document published in The New York Times on 7 April 1983 confirmed that a decision was made in April 1982 - shortly after the coup against General Romeo Lucas Garcia - to allocate an additional $2.5 million for CIA operations within Guatemala. These programs were part of a larger program of CIA operations in Central America justified by the need of "arms interdiction". This was the same rationale given by the administration for providing $19.5 million to the Contra program in 1981. This "arms interdiction program" used Argentine military personnel as opposed to American personnel directly. The New York Times journalist Leslie Gelb explained that "Argentina would be responsible, with funds from North American intelligence, of attacking the flux of equipment which was transiting Nicaragua to El Salvador and Guatemala". In actuality, the primary function of Argentine personnel in Guatemala and elsewhere in Central America was in a military advisory role. The involvement of Argentine intelligence forces in Guatemala and elsewhere occurred within the context of Operation Charly, a US-backed or US-led program in which Argentine personnel functioned as auxiliaries for the American personnel in Central America. The CIA and Argentine advisors cooperated closely in Guatemala, El Salvador, Honduras and in training the Nicaraguan FDN, especially during 1981-82. Argentina's involvement with the Guatemalan security services allegedly included direct involvement in running death squads. In 1999 the remains of two specific Guatemala citizens were found in a mass grave. The remains were discovered to be Guatemala's diary death squad victims, Amancio Samuel Villatoro and Sergio Saúl Linares Morales who went missing in 1984. Both men were abducted on separate incidents but were never seen by their families again. As a result of accords signed with the Argentine government in October 1981, over two hundred Guatemalan officers received training in Argentina
