APNewsBreak: Major Problems Found In Iraq Spending

But the government has no central data base of who all these contractors are, what services they provide, and how much they're paid. The Pentagon has failed to provide enough trained staff to watch over them, creating conditions for waste and corruption, the commission says.

In Iraq, the panel worries that as U.S. troops depart in larger numbers, there will be too few government eyes on the contractors left to oversee the closing of hundreds of bases and disposal of mountains of federal property.

At Rustamiyah, a seven-acre (three-hectare) forward operating base turned over to the Iraqis in March, the military population plunged from 1,490 to 62 in just three months. During the same period, the contractor population dropped from 928 to 338, leaving more than five contractors for every service member.

In Afghanistan, where President Barack Obama has ordered a large increase of U.S. troops, existing bases will have to expand and new ones will be built — without proper oversight unless the Pentagon rapidly changes course.

One commander in Afghanistan told the commission he had no idea how many contractors were on and off his base on a daily basis. Another officer said he had property all over his installation but didn't know who owned it or what kind of shape it was in.
