14. During these air strikes, 10.086 pieces of PGU-14 were fired, strafing such targets as armoured vehicles, trucks and bunkers. Ex-act locations of targets and PGU-14 ammunition quantity, which were spent for six at-tacks, are still unknown. But for one target, which was located near Sarajevo at suburb settlement Hadzici it was possible to collect more information. Two targets, an ammunition depot and the tanks and armoured vehicles maintenance facility, were attacked at the Hadzici location. During the five air strikes, 3.400 DU projectiles of PGU-14 ammunition were fired onto these targets. One of the targets was located within the urban part of the settlement, while another one was at suburb part of the settlement. Research points to very large number of unknown locations and uncompleted data on quantity of ammunition PGU-14 that was fired onto individual targets. There is disproportion between points of impact of DU penetrators into hard surfaces and number of located penetrators (ricochet effect), which in longer time period increases health risks for civilian population. Purpose of this paper is to perform an estimation of the dispersion zone with ground-penetrated projectiles PGU-14 using ballistic trajectory simulation for aircraft gun GAU-8/A and ammunition PGU-14 fired from aircraft A-10 and available input data such as aircraft ve-locity during the air strikes and ballistic performances of projectile PGU-
14. In order to obtain final dimension of the hit dispersion pattern, theoretical results are corrected by us-ing a dispersion figure gained from a real combat action. For this purpose, a detailed analysis of video-records (1995-2008 years) of combat actions carried by aircrafts A-10 on area targets without anti-aircraft protection and under conditions of very intensive anti-aircraft fire. Hit probability is determined on the base of US researches, which were performed during 1978 and 1979, in order to simulate attacks on Russian tanks under low attack angles. Based on the estimated number of hits for armoured or other hard targets, it is possible to approximately determine dispersion of PGU-14 ammunition during air strikes in target zone near urban areas.
