WASHINGTON, Oct. 31  An independent panel has sharply criticized the Army for failing to train enough experienced contracting officers, deploy them quickly to war zones like Iraq and Afghanistan and ensure that they properly manage billions of dollars in contracts to supply American troops in the field, according to officials briefed on its findings.

In a wide-ranging report to be made public on Thursday, the panel said these and other shortcomings had contributed to an environment in Iraq and Kuwait that allowed waste, fraud and other corruption to take hold and flourish.

The report does not address any suspected crimes by soldiers or civilian contractors; those are being pursued by investigators from the Army and the Justice Department. Nor does it single out individuals for blame.

But the six-member panel, appointed in August by Army Secretary Pete Geren, levels a stinging indictment of how the Army oversees $4 billion a year in contracts for food, water, shelter and other supplies to sustain United States forces in Iraq, Kuwait and Afghanistan. The panel also blames senior Army leaders for not responding more swiftly to the problems, despite warning signs like severe shortages of contracting officers in the field. “The Iraq-Kuwait-Afghanistan contracting problems have created a crisis,” the report states.
