The objectives of KFOR are to establish and maintain a secure environment in Kosovo, including public safety and order; to monitor, verify and when necessary, enforce compliance with the agreements that ended the conflict; and to provide assistance to the UN Mission in Kosovo (UNMIK). The Contact Group countries have said publicly that KFOR will remain in Kosovo even after Kosovo's future status is determined (i.e., whether it becomes independent or remains part of Serbia).
KFOR contingents were originally grouped into regionally-based multinational brigades. The brigades were responsible for a specific area of operations, but under a single chain of command under the authority of Commander KFOR. Beginning in 2005, KFOR transitioned to a more flexible Task Force structure, which allows the Commander of KFOR (COMKFOR) to more easily deploy units out of the regions where they are based.
At its height, KFOR troops numbered 50,000 and came from 30 different NATO / Non-NATO nations. The nations contributing the most to KFOR at the time included the United Kingdom (19,000 troops), the United States (7,000), France (7,000), Germany (6,000), Italy (5,000), Russia (3,000?), The Netherlands (2,000), Ukraine (1,300), and Spain (1,200) .
Other contributing NATO Nations include Belgium, Bulgaria, Canada, Czech Republic, Denmark, Estonia, Greece, Hungary, Iceland, Lithuania], Latvia, Luxembourg, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, and Turkey.
Other contributing non-NATO Nations have included Argentina, Armenia, Austria, Azerbaijan, Finland, Georgia, Ireland, Morocco, India, Malaysia, the Philippines, Sweden, Switzerland, and the Arab Emirates.
