POL (petroleum, oil and lubricants) truck connections are used by Hungarians to refuel western aircraft at Taszar Air Base near Vesprem, Hungary. Air Force and Army units from across Europe and the United States combined forces from 16-21 November, 1995, to survey the condition of four airfields in Hungary for possible use by U.S. forces should they be sent as a peacekeeping force in Bosnia. Bases surveyed were Fokto, a former Soviet helicopter base; Taszar, an active Hungarian Air Base with three Mig-29 squadrons; Sarmellek, a former Soviet Air Base, now a civilian airport supporting some military; and Kiskunlachaza, a closed Soviet Mig base in caretaker status
