Thousands of U.S. troops are being barred from overseas duty because they are so deep in debt they are considered security risks. The number of troops held back has climbed dramatically in the past few years.

The Pentagon contends financial problems can distract personnel from their duties or make them vulnerable to bribery and treason. As a result, those who fall heavily into debt can be stripped of the security clearances they need to go overseas.

Data supplied to the AP by the Navy, Marines and Air Force show that the number of clearances revoked for financial reasons rose every year between 2002 and 2005, climbing from 284 at the start of the period to 2,654 last year.
