The Kosovo Force (KFOR) is a NATO -led international peacekeeping force which was responsible for establishing a secure environment in KOSOVO. KFOR entered Kosovo on 11 June 1999, two days after the adoption of UN Security Council Resolution 1244. At the time, Kosovo was facing a grave humanitarian crisis, with military forces from the FRY and the KLA in daily engagement. Nearly one million people had fled Kosovo as refugees. KFOR has gradually transferred responsibilities to the Kosovo Police and other local authorities. As of 2006, KFOR consisted of appx 16,000 troops from 25 NATO countries and non-NATO 12 countries and gradually decreasing force due to the security environment of Kosovo.

NATO’s initial mandate was:[6] to deter renewed hostility and threats against Kosovo and to establish and maintain a secure environment in Kosovo, including public safety and civil order; to demilitarize the Kosovo Liberation Army; to support the UNMIK and to coordinate with and support the international civil presence. The infantry platoon level of Mongolian troops participated KFOR with Belgium I Coy under French-led battalion from OCT2005 to OCT2007.
