Batallón de Inteligencia 601
# Batallón de Inteligencia 601

The Batallón de Inteligencia 601 (Spanish for "601 Intelligence Battalion") was a special military intelligence service of the Argentine Army whose structure was set up in the late 1970s, active in the Dirty War and Operation Condor, and disbanded in 2000. Its personnel infiltrated and collected information on guerrilla groups and human rights organisations; and coordinated killings, kidnappings and other abuses.

The Batallón was under the orders of Guillermo Suárez Mason and ultimately reported to junta leader Leopoldo Galtieri. The unit took part in Luis García Meza Tejada's Cocaine Coup in Bolivia in 1980 and trained Contra units in Lepaterique base in Honduras in the 1980s. It also trained members of the Honduran Battalion 316.
