A wounded officer from the Atlacatl Battalion, second right, is evacuated by soldiers during a military operation in pursuit of guerrillas from the Frente Farabundo Martí para la Liberación Nacional, Farabundo Martí National Liberation Front, FMLN, in Tenancingo, El Salvador, September 27, 1983. Rapid reaction battalions were trained in counterinsurgency tactics to combat guerrilla warfare and were designed and funded by the United States military. The twelve-year armed conflict would claim over 75,000 lives before peace negotiations concluded in 1992.
