Training the Military to Manage Contractors During Expeditionary Operations: Overview and Options for Congress [Updated December 17, 2008] [open pdf - 1MB]
From the Summary: "The Department of Defense (DOD) is responsible for performing a wide range of expeditionary missions, including domestic emergency operations and military operations outside of the continental United States. DOD increasingly relies on contractors during expeditionary operations to perform a wide range of services. For example, more contractors are working for DOD in Iraq and Afghanistan than are U.S. military personnel. As a result, military personnel in the field are increasingly interacting with and responsible for managing contractors. Yet many observers argue that the military is not sufficiently prepared to manage contractors during expeditionary missions. [...] This report examines these steps being taken by DOD and options for Congress to monitor DOD's efforts to comply with P.L. [Public Law] 110-181."
