As the CRS report notes: "Because the estimates of Afghan casualties contained in this report are based on varying time periods and have been created using different methodologies, readers should exercise caution when using them and should look to them as guideposts rather than as statements of fact." It should also be noted that statistics on Afghan civilian casualties did not start to be collected until 2007. Nor are there any figures for the number of insurgents killed or wounded.
However, even with these constraints, there is some useful information.
The total numbers of American soldiers killed from 7 October 2001 to 29 September 2011 during Operation Enduring Freedom are as follows:
As a result of Hostile incidents 1,411
As a result of non-hostile incidents 367
Total number of Wounded in Action 14,239
The annual breakdown for US troops is shown in the following table:
The figures for Coalition troops (below) do not include the numbers of Wounded in Action.
