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.
