Borisav Jović's memoirs show that on 5 December 1991 Milošević ordered the JNA troops in BiH to be reorganised and its non-Bosnian personnel to be withdrawn, in case recognition would result in the perception of the JNA as a foreign force; Bosnian Serbs would remain to form the nucleus of a Bosnian Serb army. Accordingly, by the end of the month only 10–15% of the personnel in the JNA in BiH was from outside the republic. Silber and Little note that Milošević secretly ordered all Bosnian-born JNA soldiers to be transferred to BiH. Jović's memoirs suggest that Milošević planned for an attack on Bosnia well in advance.
