Linda Woodford spent the last 15 years of her career inserting phony numbers in the U.S. Department of Defenses accounts. Every month ... the Navy would [dump] numbers on the Cleveland, Ohio, office of the Defense Finance and Accounting Service, the Pentagons main accounting agency. Using the data they received, Woodford and her fellow DFAS accountants there set about preparing monthly reports to square the Navys books with the U.S. Treasurys. And every month, they encountered the same problem. Numbers were missing. Numbers were clearly wrong. Numbers came with no explanation of how the money had been spent or which congressional appropriation it came from. Woodford and her colleagues were told by superiors to take unsubstantiated change actions - in other words, enter false numbers, commonly called plugs, to make the Navys totals match the Treasurys. And plugging isnt confined to DFAS. Former military service officials say record-keeping at the operational level throughout the services is rife with made-up numbers to cover lost or missing information. The Defense Departments 2012 budget totaled $565.8 billion. How much of that money is spent as intended is impossible to determine. The Pentagon is largely incapable of keeping track of its vast stores of weapons, ammunition and other supplies. It has amassed a backlog of more than half a trillion dollars in unaudited contracts with outside vendors; how much of that money paid for actual goods and services delivered isnt known.
