The ZU-23-2 was extensively employed during the Lebanese Civil War, mounted on a variety of civilian and military vehicles, including M113 and BTR-152 APCs, Dodge Ram (1st generation) pickup trucks, AIL M325 Command Cars, Toyota Dyna U10-series trucks, Dodge W600 medium-duty trucks and M35A1/A2 trucks. They proved very useful in urban combat, being employed in the direct fire support role by the Syrian Army, the Palestine Liberation Organization (PLO) guerrilla factions and the various Christian and Muslim Lebanese militias. In late 1983, the ZU-23-2 was used on attacks against dug-in positions held by U.S. Marine ground units serving with the Multinational Force in Lebanon (MNF II). At the time, a Marine spokesman described such antipersonnel use of the weapon as a violation of the laws of war; however, writing for the Marine Corps Gazette in 1988, Maj. W. Hays Parks dismissed this allegation as incorrect. During the Gulf War of 1991, it was a favorite weapon of the Iraqi Army, albeit used more often against ground targets such as infantry and light enemy vehicles. They tended to use it more against ground targets as the ZU-23-2 is ineffective against fast-moving jet aircraft, though later on it was proven to be relatively ineffective as it inflicted few casualties throughout the war. The ZU-23-2 also saw usage during the Georgian Civil War and at least one kill was claimed by a ZU-23-2, when Georgian forces shot down a Sukhoi Su-25 fighter-bomber jet on 4 June 1993. The ZU-23-2 has seen widespread use by both sides in the Libyan Civil War, being often mounted on technical pickup trucks. The weapon has also been heavily used in the Syrian Civil War, being installed on pickup trucks and is credited for bringing down several Syrian Air Force helicopters. Technicals equipped with ZU-23-2 autocannons have also been frequently employed against moving ground targets. During the Yemeni Civil War, ZU-23-2 autocannons are said to have engaged Saudi tanks. On 4 May 2020 ZU-23 was used by Ethiopian troops stationed in Somalia as part of the African Union Mission to Somalia (AMISOM) to mistakenly shoot down an Embraer EMB 120RT Brasilia transporting medical supplies and mosquito nets while on approach to Bardalee, Somalia, killing all six people on board. The confusion arose from the fact the airplane was approaching from the west, instead of the usual easterly landing direction, and overflew the airfield at a low altitude due
