In January 2021 a Russian truck-mounted Pantsir S1 (SA-22) air-defense system captured in Libya was turned over to the U.S. at a German airbase. The UAE had, with assistance from American commandos and an American C-17 transport, obtained the Pantsir S1 and flown it out of an improvised landing strip west of Tripoli. The UAE had apparently arranged to buy the Pantsir S1 from one of the Libyan militias that captured the Pantsir when they accompanied Turkish mercenaries to capture an airfield,
This confirms rumors that the Americans had acquired a Pantsir in 2020 with the help of UAE. The Russians and the UAE had long supported the LNA (Libyan National Army) with weapons, air support and logistical services. This alliance had made it possible for the LNA to control over 80 percent of Libya by late 2020. Then the Turks agreed to provide military support, including thousands of Syrian Arab mercenaries, to help the GNA (Government of National Accord) push back the LNA forces that had besieged Tripoli since early 2019 and were on the verge of taking the city and eliminating the GNA in late 2019 when the Turkish forces began arriving.
