In 2004 and 2005, the United States bought 185,000 AK-47s from an Eastern European country -- after Iraqis rejected U.S.-made M-16 assault rifles -- as part of a $2.8 billion program to deliver military equipment to Iraq. But a recent Government Accountability Office report said that 110,000 of them were unaccounted for, with about 30 percent of all arms distributed to Iraqi forces by the United States since 2004 missing.
