USAS, an acronym for United States Army School of the Americas, is commonly known for being an institution for training military officers and soldiers in South and Central America. However, there are several synonyms that can represent this acronym. One of them is the Western Hemisphere Institute for Security Cooperation (WHINSEC), which is the institution's current name. Additionally, the School of Inter-American Affairs (SIIA), and the School of the Americas (SOA), were its previous names. These synonyms represent the same training hub where military personnel from various Latin American countries were trained in combat operations, often with human rights controversies. By using different names over time, the institution has aimed to decrease the negative connotation associated with its use.
