CRS – The Cost of Iraq, Afghanistan, and Other Global War on Terror Operations Since 9/11, Amy Belasco, Specialist in U.S. Defense Policy and Budget. December 8, 2014.

“With enactment of the FY2014 Consolidated Appropriations Act on January 1, 2014 (H.R. 3547/P.L. 113-73), Congress has approved appropriations for the past 13 years of war that total $1.6 trillion for military operations, base support, weapons maintenance, training of Afghan and Iraq security forces, reconstruction, foreign aid, embassy costs, and veterans’ health care for the war operations initiated since the 9/11 attacks. Of this $1.6 trillion total, CRS estimates that the total is distributed as follows:
• $686 billion (43%) for Operation Enduring Freedom (OEF) for Afghanistan and other counterterror operations received;
• $815 billion (51%) for Operation Iraqi Freedom (OIF)/Operation New Dawn(OND);
• $27 billion (2%) for Operation Noble Eagle (ONE), providing enhanced security at military bases; and
• $81 billion (5%) for war-designated funding not considered directly related to the Afghanistan or Iraq wars. About 92% of the funds are for Department of Defense (DOD), 6% for State Department foreign aid programs and diplomatic operations, 1% for Department of Veterans Administration’s medical care for veterans. In addition, 5% of the funds (across agencies) are for programs and activities tangentially-related to war operations. The FY2015 war request for DOD, State/USAID, and Veterans Administration Medical totals $73.5 billion including $58.1 billion for Afghanistan, $5.0 billion for Iraq, $ 100 million for enhanced security, and $10.4 billion for other war-designated funding. These totals do not reflect the new FY2015 request submitted in November 2014 to cover expenses for Operations Inherent Resolve (OIR) that began with airstrikes launched in late August 2014, to aid Syrian insurgents and the Iraq government to counter the takeover of territory by the Islamic State (IS). The Administration submitted a $5.5 billion FY2015 budget amendment for this operation that Congress is considering. Including the new request, the FY2015 war funding now totals $79.0 billion.”
