AK-47
They were used in the Cambodian Civil War and the Cambodian–Vietnamese War. During the 1980s, the Soviet Union became the principal arms dealer to countries embargoed by Western nations. This included Middle Eastern nations such as Iran, Libya, and Syria, which welcomed Soviet Union backing against Israel. After the end of the Soviet Union (1989/90), AK-47s were sold openly and on the black market to any group with cash, including drug cartels and dictatorial states. More recently they have been seen in the hands of Islamic groups such as Al-Qaeda, ISIL, and the Taliban in Afghanistan and Iraq, and FARC, Ejército de Liberación Nacional guerrillas in Colombia.
