The United States’ Special Inspector General for Afghanistan Reconstruction just released its “Afghan National Security Forces: Actions Needed to Improve Weapons Accountability” report for July.

The report revealed that a total of 747,000 weapons supposedly given to the Afghan National Security Forces by the U.S. Department of Defense are now unaccounted for.

According to the report, 465,000 of these weapons are small arms that include, “…rifles, pistols, machine guns, grenade launchers, and shotguns.”

The Department of Defense relies primarily on two programs to track the flow of weapons to Afghanistan’s security forces: The Security Cooperation Information Portal (SCIP) and the Operational Verification of Reliable Logistics Oversight Database (OVERLORD).

Both of these programs were found to have major errors and discrepancies. In fact, a whopping 43% of the serial numbers (used to identify and track each individual weapon) in the OVERLORD system were found to have, “missing information and/or duplication.”

On top of that, the report found that as of November 2013, the U.S. had provided Afghanistan’s Security Forces with nearly 113,000 more weapons than they actually needed (based on the “Tashkil”, the official list of requirements for the ANSF issued by the Afghan government).

The SIGAR report also warns that these weapons could easily find their way into the hands of hostile groups like the Taliban, if they haven’t already:

“Without confidence in the Afghan government’s ability to account for or properly dispose of these weapons, SIGAR is concerned that they could be obtained by insurgents and pose additional risks to Afghan civilians and the ANSF.”
