The number of U.S. servicemen and women killed in the "Global War on Terror (GWOT) and later Overseas Contingency Operations (OCO)" since 9/11/01, according to a new "In Focus" brief from the Congressional Research Service -- U.S. War Costs, Casualties, and Personnel Levels Since 9/11.
Approximately 62% (36, 885) of all war-related incidents that resulted in U.S. military casualties have occurred during operations in Iraq, including Operation Iraqi Freedom, Operation Inherent Resolve, and Operation New Dawn. Troops killed or wounded in operations primarily associated with Afghanistan—Operation Enduring Freedom and Operation Freedom’s Sentinel—represent 38% (22,884) of the remainder.
Though most U.S. war casualties since 9/11 have occurred within the territories of Iraq and Afghanistan, 383 U.S. personnel have died during contingency operations elsewhere, such as at locations in Africa, South Asia, Central Asia, Europe, the United States, the Middle East, or at sea.
According to the CRS:
Data compiled by the Department of Labor suggest that 3,413 civilian employees under contract with the U.S. government for public works or national defense have been killed in Afghanistan and Iraq in the years since 9/11. An additional 38,953 have sustained work-related injuries that resulted in four or more lost work days, the highest threshold for injury (excluding death).
