Additionally, as of a September 1976, the Defense Intelligence Agency reported that US intelligence services were quite aware of the infrastructure and goals of Operation Condor. They realized that "Operation Condor" was the code name given for intelligence collection on "leftists", Communists, Peronists or Marxists in the Southern Cone Area. The intelligence services were aware that it was security cooperation among several South American countries' intelligence services (such as Argentina, Paraguay, Uruguay, and Bolivia) with Chile as the epicenter of the operation. The DIA noted that Argentina, Uruguay, and Chile were already fervently conducting operations, mainly in Argentina, against leftist targets. Members of SIDE were also operating with Uruguayan military Intelligence officers in an operation carried out against the Uruguayan terrorist organization, the OPR-33. The report also noted that a large volume of U.S. currency was seized during the combined operation.
