by the RS Ministry of Interior, referred to 641 Serb victims in the Bratunac-Srebrenica-Skelani region. The accuracy of these numbers is challenged: the OTP noted that although Ivanišević's book estimated that around 1,200 Serbs were killed, personal details were only available for 624 victims. The validity of labeling some of the casualties as "victims" is also challenged: studies have found a significant majority of military casualties compared to civilian casualties. This is in line with the nature of the conflict—Serb casualties died in raids by Bosniak forces on outlying villages used as military outposts for attacks on Srebrenica (many of which had been ethnically cleansed of their Bosniak majority population in 1992). For example, the village of Kravica was attacked by Bosniak forces on Orthodox Christmas Day, 7 January 1993. Some Serb sources such as Ivanišević allege that the village's 353 inhabitants were "virtually completely destroyed". In fact, the VRS' own internal records state that 46 Serbs died in the Kravica attack: 35 soldiers and 11 civilians, while the ICTY Prosecutor's Office's investigation of casualties on 7 and 8 January in Kravica and the surrounding villages found that 43 people were killed, of whom 13 were obviously civilians. Nevertheless, the event continues to be cited by Serb sources as the key example of crimes committed by Bosniak forces around Srebrenica. As for the destruction and casualties in the villages of Kravica, Šiljković, Bjelovac, Fakovići and Sikirić, the judgement states that the prosecution failed to present convincing evidence that the Bosnian forces were responsible for them, because the Serb forces used artillery in the fighting in those villages. In the case of the village of Bjelovac, Serbs even used warplanes. The most up-to-date analysis of Serb casualties in the region comes from the Sarajevo-based Research and Documentation Centre, a non-partisan institution with a multiethnic staff, whose data have been collected, processed, checked, compared and evaluated by international team of experts.Heil, Rebekah (23 June 2007).

The RDC's extensive review of casualty data found that Serb casualties in the Bratunac municipality amounted to 119 civilians and 424 soldiers. It also established that although the 383 Serb victims buried in the Bratunac military cemetery are presented as casualties of ARBiH units from Srebrenica, 139 (more than one third of the total) had fought and died elsewhere in Bosnia and
