The website iCasualties.org lists 2,455 servicemembers and 10 CIA operatives as having died in Operation Enduring Freedom and Operation Freedom's Sentinel, including 49 who died in support of other OEF operations. This gives a total of 2,406 deaths of servicemen in support of operations in Afghanistan.

The iCasualties.org figure of 2,406 is higher than the Department of Defense's officially stated figure, although according to the website all of the names listed at iCasualties.org have been confirmed by the Department of Defense.
