Fifty-two Centaur I tanks were donated in early 1946 to the Greek Army, during the opening stages of the Greek Civil War but they were kept in storage due to the lack of trained personnel. In 1947, the first Greek officers returned from training courses in the United Kingdom and training of tank crews began. In April 1948, the Centaurs were organised in three Centaur tank companies initially numbered II, IX and XI, but a year later were renumbered 381, 382, 383 and temporarily attached to Reconnaissance Regiments 391, 392, and 393. The Centaurs saw limited service in the war because battles were fought mainly on mountainous areas, but proved useful in supporting infantry units and in defence of inhabited areas. After the end of the war, in October 1949, the three Centaur companies were organised into the 391 Tank Regiment. The Centaurs were replaced by US built M47s and in 1962 were sold and scrapped. One Centaur is preserved in the Greek Army Tank Museum.
