September 1986
CIA-supplied FIM-92 Stinger MANPADS were used in combat for the first time near Jalalabad on September 26, 1986, when Mujahideen fighters shot down three Soviet Mi-24 Hind helicopter gunships. The Stingers proved devastatingly effective; Soviet helicopter losses spiked by over 300% in subsequent months. The introduction of the Stinger fundamentally altered Soviet air strategy for the remainder of the war.
