[2] During the Yugoslav Wars, Radić served as a Captain in the Yugoslav People's Army (JNA), serving as the commander of the Special Infantry Unit, 1st Battalion, 1st Guards Motorised Brigade.
[citation needed] Thought to have participated in the subsequent Vukovar massacre, Radić was indicted in 1995, along with Mile Mrkšić, Veselin Šljivančanin and Slavko Dokmanović, by the International Criminal Tribunal for the Former Yugoslavia (ICTY).
The indictment accused him of "responsibility for the mass killing at Ovčara, near Vukovar, of approximately 260 captive non-Serb men".
[3] Radić was formally charged with "crimes against humanity and war crimes including persecutions: Political, racial, and religious grounds, extermination, murder, torture, inhuman acts and cruel treatment", and pleaded not guilty to all counts.
[4] He was acquitted on all counts on 27 September 2007, after it was determined that his soldiers had provided the initial security for Vukovar hospital during the massacre, but the cross-examination of three witnesses failed to produce evidence that Radić himself had knowledge of the massacre at Ovčara during the event.
