What GAO Found
In fiscal year 2018, Congress authorized $48.6 billion and appropriated $50.7 billion for operation and maintenance (O&M) overseas contingency operations (OCO), and the Department of Defense (DOD) reported obligating $46.5 billion. DOD reported obligating these funds for war-related activities, including security forces training missions, in-theater base support operations (dining facilities, laundry, security, and housing), ship operations, flying hours, equipment maintenance and repair, and transportation. The amounts reported as obligated in some sub-activity groups exceed the congressionally directed amounts for those same groups as a result of transfers and reprogrammings.
Why GAO Did This Study
According to DOD, since September 2001, Congress has appropriated approximately $1.8 trillion to DOD for OCO, primarily in Iraq and Afghanistan. The National Defense Authorization Act for Fiscal Year 2019 included a provision for GAO to report on how funds authorized to be appropriated for fiscal year 2018 for OCO were obligated. In fiscal year 2018, O&M OCO amounts comprised approximately 76 percent of DOD's OCO appropriations total of $66.8 billion. This report describes how amounts authorized and appropriated for O&M OCO activities were obligated by DOD for fiscal year 2018.
To determine how DOD obligated the amounts authorized and appropriated for O&M OCO activities in fiscal year 2018, GAO first compared authorized and appropriated O&M OCO amounts by sub-activity group. GAO then analyzed obligation data provided by DOD related to the same sub-activity groups.
