Atlacatl Battalion Training: U.S. Curriculum, Human Rights, and Rules of Engagement Declassification

SUMMARY

The Atlacatl Battalion was an elite Salvadoran military unit trained by the United States during the Salvadoran Civil War (1979-1992). The unit became notorious for alleged human rights abuses, including its involvement in the El Mozote massacre in December 1981. The U.S. government provided significant military aid and training to the Salvadoran armed forces, including the Atlacatl Battalion, with training reportedly taking place at Fort Bragg and by U.S. Special Forces. Critics allege that despite U.S. involvement, the training either failed to prevent or inadvertently contributed to human rights violations by the battalion.

This dossier investigates whether declassified U.S. government documents explicitly detail the curriculum, human rights screening processes, and rules of engagement provided during the Atlacatl Battalion's training. Researchers often seek such documentation to understand the extent of U.S. knowledge and responsibility regarding the unit's actions. While numerous declassification repositories exist, the direct availability of specific training manuals, human rights protocols, or engagement rules for this particular unit remains an open question.
