IV Army Corps (Greece)

The IV Army Corps (Δ' Σώμα Στρατού, abbr. Δ' ΣΣ) is an army corps of the Hellenic Army. Established before the First World War, it served in all conflicts Greece participated in until the German invasion of Greece in 1941. Re-established in 1976, it has been guarding the Greco-Turkish land border along the Evros River, and thus the most powerful formation in the Hellenic Army.

History
The IV Army Corps was established by Royal Decree on 23 December 1913 (O.S.) at Kavala, East Macedonia, during the reorganization of the Hellenic Army following the Balkan Wars. When East Macedonia was occupied by German and Bulgarian forces during World War I, the entire Corps was carried by rail to Görlitz, Germany, as "guests" of the German Government, where they remained for almost three years.

During the Greco-Turkish War it was renamed the Thracian Army and was stationed in Adrianople. In 1922, after the defeat of the Hellenic forces in Asia Minor, it covered the withdrawal of many units to Thrace.

In November, 1940 during the Greco-Italian War it was renamed again as East Macedonia Army Group (ΤΣΑΜ) joining the 1st Army which was fighting in Albania. In April 1941 it surrendered to German forces.

In 1976 the Corps was reformed in Xanthi and currently is the most powerful formation of the Hellenic Army.
