The Small Arms Survey published in July 2015 a detailed report titled "Under Attack and Above Scrutiny? Arms and Ammunition Diversion from Peacekeepers in Sudan and South Sudan, 2002-14" by Eric G. Berman and Mihaela Racovita. It is the first independent review of weapons lost in peacekeeper operations.
There were more than 100 attacks on peacekeepers in Sudan and South Sudan between 2005 and 2014. At least half of them resulted in the loss of arms and ammunition, most of them in the Darfur region.
