20. Soviet and Afghan Militaries Against Rebel Soldiers and Civilians, 1979-1981: 3,042 Casualties
The Soviet invasion of Afghanistan and the ensuing war, which lasted nearly an entire decade, led to massive casualties, including civilians, and the transformation of Afghanistan from a thriving, modern society to the oppressive, primitive civilization that exists there today.
During the war, there were numerous reports of the Soviets using chemical weapons, often indiscriminately among civilian populations. Between 1979 and 1982 there were 43 chemical weapons attacks, which killed over 3000 people, many of them civilians. The use of chemical weapons became so widespread that it was reported in every area of Afghanistan that had resistance activity.
