Operation Grapple was the codeword used to cover UK defence operations in support of the UN peacekeeping missions in the former Yugoslavia ; including the deployment of British forces in Bosnia and Croatia from October 1992 until December 1995 as part of the United Nations Protection Force (UNPROFOR). UNPROFOR would eventually hand over the peacekeeping mission in Bosnia to NATO's Implementation Force (IFOR) in winter 1995. The British participation in the IFOR was called Operation Resolute; the whole NATO mission was called Operation Joint Endeavour. The IFOR mission would last approximately a year, before it transitioned to the follow-on Stabilisation Force in Bosnia and Herzegovina (SFOR).
