This is 42 nations contributing for approximately 67,700 troops, a number that can fluctuate from day to day. This also doesn't represent the number of coalition troops on the ground at a given time. The force is under the command of U.S. Gen. Stanley McChrystal.
The ISAF units have some regions of distinction. For example, the northern posts are heavily German, while Spanish and Italian troops are in the western part of the country near Herat. Canadian and British forces have a stronger presence in the south of the country around Kandahar.
