Excerpts:

The United States agreed to provide a force of approximately 7,000 US personnel as part of the NATO KFOR to help maintain a capable military force in Kosovo and to ensure the safe return of Kosovar refugees. The US supports KFOR by providing the headquarters and troops for one of the four NATO sectors. The US also provides personnel, units and equipment to other components of the KFOR organization.
