The "Tercer Cuerpo" (Third Army Corps) was a military unit of the Argentine Army, established during the late 20th century. It played a significant role during the Dirty War, a period of state terrorism in Argentina from 1976 to 1983, where the government targeted suspected dissidents. The corps was primarily responsible for operations in the Buenos Aires region and was involved in various human rights violations. The Tercer Cuerpo was known for its involvement in clandestine detention centers, where many individuals were illegally held and tortured. Its actions contributed to the disappearance of thousands of people, leading to ongoing debates about accountability and justice in Argentina. The legacy of the Tercer Cuerpo remains a critical aspect of the country's history.
