The Greek First Army (, Proti Stratia), is the highest formation of the Hellenic Army and its only extant field army. The First Army was created in March 1947, during the Greek Civil War. It controlled the II and III Corps, with Volos as its headquarters. It was abolished on 10 February 1948, and re-established in 1951 with its HQ at Larissa, where it remains to this day. Its CO is always a Lieutenant General.
