Aiken, then 30 years old, was in his second month of physical and psychological reconstruction at Fort Bliss in El Paso, Texas, after two tours of combat duty had left him shattered. His war-related afflictions included traumatic brain injury, severe post-traumatic stress disorder (PTSD), abnormal eye movements due to nerve damage, chronic pain, and a hip injury.



But the problem that loomed largest that holiday season was different. Aiken had no money. The Defense Department was withholding big chunks of his pay. It had started that October, when he received $2,337.56, instead of his normal monthly take-home pay of about $3,300. He quickly raised the issue with staff. It only got worse. For all of December, his pay came to $117.99.

The money the military took back from Aiken resulted from accounting and other errors, and it should have been his to keep. Further, even after Aiken complained, the Defense Department didn't return the bulk of the money to Aiken until after Reuters inquired about his case.



The Pentagon agency that identified the overpayments, clawed them back and resisted Aiken's pleas for explanation and redress is the Defense Finance and Accounting Service, or DFAS (pronounced "DEE-fass"). This agency, with headquarters in Indianapolis, Indiana, has roughly 12,000 employees and, after cuts under the federal sequester, a $1.36 billion budget. It is responsible for accurately paying America's 2.7 million active-duty and Reserve soldiers, sailors, airmen and Marines.



It often fails at that task, a Reuters investigation finds.

Because of its persistent inability to tally its accounts, the Pentagon is the only federal agency that has not complied with a law that requires annual audits of all government departments. That means that the $8.5 trillion in taxpayer money doled out by Congress to the Pentagon since 1996, the first year it was supposed to be audited, has never been accounted for. That sum exceeds the value of China’s economic output last year. -- Reuters journalist Scot J.
