The 203rd deployed to Bosnia in support of NATO stability efforts two days before Thanksgiving in 1996. The unit touched down in the region as part of Operation Joint Endeavor (IFOR) just as the International Criminal Tribunal for the former Yugoslavia began in earnest, with highly publicized arrest warrants for senior figures in the conflict including Radovan Karadžić and Ratko Mladić. While deployed, the unit identified and documented more than 300 novel pieces of ordnance, and inspected combat vehicles and manufacturing plants. Five times the units reporting prompted fundamental shifts in force protection posture for all deployed NATO forces. The 203rd's work on the ground in Bosnia continued through the transition of the NATO stabilization mission to SFOR, continuing through at least March 2000. The battalion suffered one casualty in Bosnia, when in July 1997 a specialist died at a British field hospital following a motor vehicle accident north of Donji Vakuf, in the British-controlled Multi-National Division (South-West) area of operation.
