UN "Safe Area" warnings On 15 August 1994, Krstić was appointed Chief of Staff of the Drina Corps. Krstić worked with his replacement to familiarize him with his roles and function until 1 September, and then worked with the former Chief of Staff whom he would be replacing to learn his new post until 28 September. He was then briefed about Bosnian operations coming from the direction of Tuzla, Živinice, Kladanj, and Olovo against Serbian civilians. His predecessor also briefed him and told him that, despite the status of the safe area accorded to Srebrenica and Žepa and the obligations stemming from agreements on demilitarization, the forces of the 28th Mountain Division of the Eastern Bosnia Corps in Srebrenica and Žepa were, in fact procuring from Tuzla and Kladanj or directly from Sarajevo more weapons in addition to the light or infantry weapons they already had. There were numerous reports from Serb intelligence sources of the BiH Army troop movements in and out of protected enclaves carrying arms, reconnoitering Serb positions, and other military actions against Tuzla, Živinice, and Kladanj, all using UN protectorates as a base of operations in the region and operating under the radar so as to avoid notice by UNPROFOR. Krstić stayed at his post at the Corps Command until 1 November 1994, whereupon he established a brigade which was deployed at the area of the Herzegovinian Corps to combat the offensive which was mounted by the Eastern Bosnia Corps from the area of Bjelašnica and Igman towards Treskavica and Trnovo. He remained in the area of Treskavica and Trnovo until mid-December 1994, whereupon he returned to his post as the commander of the Corps in Vlasenica. He was again briefed about the situation with respect to operations that the Bosniak command of the 28th Division in Srebrenica, acting upon orders from the Main Staff of the 2nd Corps in Tuzla, was conducting towards the positions of the Drina Corps, in particular, at the Milici municipality, Han Pijesak, and the Vlasenica municipality. He was also briefed about intel on the continuation of the army, weapons and ammunitions supply to the members of the 28th Brigade at the protected area. They
