A total of 3,196 active-duty soldiers deserted the Army last year, or 853 more than previously reported, according to revised figures from the Army.

The new calculations by the Army, which had about 500,000 active-duty troops at the end of 2006, significantly alter the annual desertion totals since the 2000 fiscal year.

In 2005, for example, the Army now says 2,543 soldiers deserted, not the 2,011 it had reported. For some earlier years, the desertion numbers were revised downward.

National Public Radio first reported on Tuesday that the Army had been inaccurately reporting desertion figures.
