Secret Anti-Communist Army
The Secret Anti-Communist Army (Spanish: Ejército Secreto Anticomunista, ESA) was a front organization that operated in Guatemala and El Salvador during the Guatemalan Civil War. Like other earlier organizations, such as the MANO and the CADEG, the ESA existed as a front for a covert program of selective assassination by the Guatemalan security services.
