The Pentagon did not properly track $1 billion worth of military equipment sent to Ukraine, according to a watchdog report. The report from the Pentagon Inspector General says that while the Defense Department has improved its ability to track military aid sent to Ukraine, it "did not fully comply" with requirements and much of the equipment sent is "delinquent," meaning it's not possible to complete an inventory of everything sent. Among the items that are designated for enhanced end-use monitoring (EEUM) are weapons like Javelin and Stinger missiles, night-vision devices, AIM-9X missiles, and Advanced Medium-Range Air-to-Air Missiles. According to the IG report, roughly $1.005 billion of the total $1.699 billion of equipment subject to end-use monitoring was not inventoried as of June 2023. The new report comes at a critical moment for Ukraine aid, as Congress debates whether to authorize a supplemental package of more than $60 billion in aid. While delinquency could suggest weapons had been stolen or diverted away from Ukrainian forces, the inspector general said it was outside the scope of its probe to determine what had happened to the weapons that were not properly tracked. "The DoD OIG now has personnel stationed in Ukraine," the report says, "and the DoD OIG's Defense Criminal Investigative Service continues to investigate allegations of criminal conduct with regard to U.S. security assistance to Ukraine."
