The U.S. provided an estimated $83 billion worth of training and equipment to Afghan security forces since 2001. This year, alone, the U.S. military aid to Afghan forces was $3 billion. Putting price tags on American military equipment still in Afghanistan isn't an easy task. In the fog of war " or withdrawal " Afghanistan has always been a black box with little sunshine. Not helping transparency, the Biden Administration is now hiding key audits on Afghan military equipment. This week, our auditors at OpenTheBooks.com reposted two key reports on the U.S. war chest of military gear in Afghanistan that had disappeared from federal websites. 1. Government Accountability Office (GAO) audit of U.S. provided military gear in Afghanistan (August 2017). 2. Special Inspector General For Afghanistan Reconstruction (SIGAR) audit of $174 million in lost ScanEagle drones (July 2020). An unnamed official told Reuters that current intelligence assessment was that the Taliban took control of more than 2,000 armored vehicles, including American Humvees, and as many as 40 aircraft that may include UH-60 Black Hawks, scout attack helicopters and ScanEagle military drones. "We don't have a complete picture, obviously, of where every article of defense materials has gone, but certainly a fair amount of it has fallen into the hands of the Taliban," White House national security adviser Jake Sullivan said.
