Operation Joint Endeavor

"Beginning in December 1995, US and allied nations deployed peacekeeping forces to Bosnia in support of Operation Joint Endeavor. Task Force Eagle, comprised of 20,000 American soldiers, was the US component of NATO's Implementation Force (IFOR) and was tasked with implementing the military elements of the Dayton Peace Accords in support of Operation Joint Endeavor. Task Force Eagle was the lead element for NATO's Multinational Division (North) or MND(N). Operation Joint Endeavor marked the first commitment of forces in NATO's history, as well as the first time since World War II that American and Russian soldiers had shared a common mission. Thousands of people were alive in Bosnia because of these soldiers' service. On 20 December 1996, the IFOR mandate ended and NATO established a new operation, Operation Joint Guard, along with a new Stabilisation Force (SFOR) to replace IFOR. Task Force Eagle remained the title for the US contingent supporting this new operation."
