Implementation Force

The Implementation Force (IFOR) was a NATO-led multinational peace enforcement force in Bosnia and Herzegovina under a one-year mandate from 20 December 1995 to 20 December 1996 under the codename Operation Joint Endeavour.

Background
NATO was responsible to the United Nations (UN) for carrying out the Dayton Peace Accords. The Dayton Peace Accords were started on 22 November 1995 by the presidents of Bosnia, Croatia, and Serbia, on behalf of Serbia and the Bosnian Serb Republic. The actual signing happened in Paris on 14 December 1995. The peace accords contained a General Framework Agreement and eleven supporting annexes with maps. The accords had three major goals: ending of hostilities, authorization of military and civilian program going into effect, and the establishment of a central Bosnian government while excluding individuals who are serving sentences or under indictment by the International War Crimes Tribunals from taking part in the running of the government. IFOR's specific role was to implement the military Annexes of The General Framework Agreement for Peace (GFAP) in Bosnia and Herzegovina.

IFOR relieved the UN peacekeeping force UNPROFOR, which had originally arrived in 1992, and the transfer of authority was discussed in Security Council Resolution 1031. Almost 60,000 NATO soldiers in addition to forces from non-NATO nations were deployed to Bosnia. Operation Decisive Endeavor (SACEUR OPLAN 40105), beginning 6 December 1995, was a subcomponent of Joint Endeavor. IFOR began operations on 20 December 1995.

The Dayton Agreement resulted from a long series of events, notably, the failures of EU-led peace plans, the August 1995 Croat Operation Storm and expelling 200,000 Serb civilians, the Bosnian Serb war crimes, in particular the Srebrenica massacre, and the seizure of UNPROFOR peace-keepers as human shields against NATO's Operation Deliberate Force.

U.S. Secretary of Defense William Perry and his Russian counterpart, Pavel Grachev agreed on October 8 that the peacekeeping operation name will be Implementation Force of the Peace Agreement on Bosnia-Herzegovina, that is without reference to NATO; other differences were unresolved at that time (chain of command, area of command and control). On October 27 they agreed that "the Russian unit will not be part of the NATO peacekeeping force, but will perform special engineering, transport and construction activites".

Admiral Leighton W. Smith Jr., Commander in Chief Allied Forces Southern Europe (CINCSOUTH), served as the first Joint Force Commander for the operation, also known as Commander IFOR (COMIFOR). He commanded the operation from IFOR's deployment on 20 December 1995 from headquarters in Zagreb, and later from March 1996 from the Residency in Sarajevo. Admiral Thomas J. Lopez commanded the operation from 31 July to 7 November 1996, followed by General William W. Crouch until 20 December 1996. Lt Gen Michael Walker, Commander Allied Rapid Reaction Corps (ARRC), acted as Land Component Commander for the operation, commanding from HQ ARRC (Forward) based initially in Kiseljak, and from late January 1996 from HQ ARRC (Main) in Ilidža. This was NATO's first ever out-of-area land deployment. The Land Component's part of the operation was known as Operation Firm Endeavour.

At its height, IFOR involved troops from 32 countries and numbered some 54,000 soldiers in-country (BiH) and around 80,000 involved soldiers in total (with support and reserve troops stationed in Croatia, Hungary, Germany, and Italy and also on ships in the Adriatic Sea). In the initial phases of the operation, much of the initial composition of IFOR consisted of units which had been part of UNPROFOR but remained in place and simply replaced their United Nations insignia with IFOR insignia.

Components
NATO member states that contributed forces included Belgium, Canada, Denmark, France, Germany, Italy, Luxembourg, the Netherlands, Norway, Portugal, Spain, Turkey, the United Kingdom, and the United States. Non-NATO nations that contributed forces included; Australia, Austria, Bangladesh, the Czech Republic, Egypt, Estonia, Finland, Hungary, Latvia, Lithuania, Malaysia, Morocco, New Zealand, Pakistan, Poland, Romania, Slovakia, Sweden, Russia, and Ukraine.
