WASHINGTON — More than 1,200 Army recruiters and assistants are under investigation on suspicion of fraud involving tens of millions of dollars from a program aimed at increasing recruitment during the Iraq war, according to papers released Monday by a congressional panel.

One person, now under prosecution, was fraudulently paid $275,000 under the recruitment program, and four others received more than $100,000 each, according to the documents, which were released by a subcommittee of the Senate Homeland Security Committee.

The panel, the Financial and Contracting Oversight Subcommittee, is scheduled to hold a hearing on Tuesday to address the case. The recruiting program was initiated in 2005 at the height of the Iraq war to address an enlistment shortfall in the Army National Guard.
