The report names a total of 25,083 people involved in the massacre in Srebrenica, 19,473 of which are said to have given orders or actively taken part in the killings, while the other individuals on the list stand accused of having indirectly contributed to the slaughter. source
So, out of the 80,000 men in total -- 25,000 were in Srebrenica? Right. I guess the 1080-km-long frontline was left pretty much undefended then. The only force involved in/around Srebrenica was the Drina Corps which numbered 14,000 at its peak (1993) and was responsible for more than 10 zones of operation in the eastern part of Republika Srpska.
