Renault FT tanks were also fielded in limited numbers during World War II, in Poland, Finland, France, Greece, Romania and the Kingdom of Yugoslavia, although they were already obsolete. In May 1940, the French Army still had seven front-line battalions, each equipped with 63 FTs, one under-strength battalion as well as three independent companies, each with 10, for a total organic strength of 504. 105 more were in service in the colonies of Morocco and Algeria and 58 in French Levant, Madagascar and Indochina. Some FT tanks had also been buried within the ground and encased in concrete to supplement the Maginot Line.
