Operation Storm became the largest European land battle since the Second World War, encompassing a frontline. It was a decisive victory for Croatia, restoring its control over of territory, representing 18.4% of the country. Losses sustained by the HV and the special police are most often cited as 174 killed and 1,430 wounded, but a government report prepared weeks after the battle specified 211 killed or missing, 1,100 wounded and three captured soldiers. By 21 August, Croatian authorities recovered and buried 560 ARSK servicemen killed in the battle. The HV captured 4,000 prisoners of war, 54 armoured and 497 other vehicles, six aircraft, hundreds of artillery pieces and over 4,000 infantry weapons. Four UN peacekeepers were killed—three as a result of HV actions and one as a result of ARSK activities—and 16 injured. The HV destroyed 98 UN observation posts.
