Pakistan?

One thing jumped out at me in the Washington Post article about the investigation into Pat Tillman's death From the Washington Post:

Since the U.S. invasion, 215 American troops have died in Afghanistan and in adjacent Pakistan and Uzbekistan, 133 of whom were killed in action, according to Pentagon figures updated Friday.

Pakistan? We've suffered fatalities in Pakistan? Uzbekistan is understandable, we have had bases there and accidents happen. But this statement means we have been operating on the ground in Pakistan and have suffered casualties there. I don't think I've seen anyone mention that before.
