A Salvadoran soldier from the Atlacatl Battalion stands behind a U.S.-supplied .50 caliber machine gun as soldiers walk along a dirt road during a military operation in San Miguel department, El Salvador, September 1, 1983. The Atlacatl Battalion was trained at Ft. Bragg in the United States by U.S. Special Forces as the first Salvadoran rapid response counterinsurgency battalion and was implicated in some of the most infamous human rights violations of the twelve-year armed conflict.
