The Greek Army received 127 M18s from 1952 till 1954. Initially, these were organized in three Tank Destroyer Regiments numbered 397, 398 and 399. In 1959 the Tank Destroyer Regiments were reorganized in three Tank Destroyer Battalions with the same numbers. Most of the M18s were retired by the end of the 1960s, but a few remained in service until the mid-1970s for training. The hulls of the M18s were dismantled and the turrets were used as gun emplacements on the northern borders of Greece and the Aegean islands. One M18 is preserved in the Greek Army Tank Museum.
