After World War II, many M18s were sold to other countries. These were rebuilt and refurbished by Brown & Root in northern Italy in the late 1940s and early 1950s, and bear data plates that indicate those rebuilds. One of the users was Yugoslavia, which received 260 Hellcats during the Informbiro period and kept some of them in reserve until the early 1990s. A number of these vehicles were later used by the Military of Serbian Krajina and Army of Republika Srpska during the Yugoslav wars. One example was used on an armored train named the "Krajina express" ("Krajina Ekspres").
