How Many Guns Did the U.S. Lose Track of in Iraq and Afghanistan? Hundreds of Thousands.

C. J. Chivers writes for The New York Times:

Early this year, a Facebook user in Baghdad using the name Hussein Mahyawi posted a photograph of a slightly worn M4 assault rifle he was offering for sale. Veterans of the latest war in Iraq immediately recognized it. It was a standard American carbine equipped with a holographic sight, a foregrip that was military-issue during the occupation and a sticker bearing a digital QR code used by American forces for inventory control. Except for one detail — an aftermarket pistol grip, the sort of accessory with which combatants of the current generation often pimp their guns — it was a dead ringer for any of the tens of thousands of M4s the Pentagon handed out to Iraqi security forces and various armed militias after toppling Saddam Hussein in 2003. And here it was on the open market, ready for bids.

Was this a surprise? No. A little more than four years after the United States withdrew all its military forces from Iraq, and not quite two years after a smaller number of American troops began returning to the country to help fight the Islamic State, the open sale of such an M4 was part of Iraq’s day-to-day arms-trafficking routine. Mahyawi’s carbine was another data point attesting to an extraordinary and dangerous failure of American arms-trafficking and public accountability and to a departure from a modern military’s most basic practice: keeping track of the guns.
