ΓΕΣ) is the general staff of the Hellenic Army, the terrestrial component of the Greek Armed Forces.

Although the first regular army units were raised as early as 1821–1822, on the outbreak of the Greek War of Independence, the first rudimentary general staff organization, in the form of the General Staff Officers Corps (Σώμα Γενικών Επιτελών), was created only in 1833, after the establishment of the independent Kingdom of Greece.

[1] In December 1945, after Liberation, and again in 1948 and 1950, when the unified Ministry of National Defence was founded, the Army General Staff was reorganized.

The First Deputy Chief heads the 1st and 4th branches along with the main combat arms (infantry, armour, artillery, special forces, etc.

), while the Second Deputy Chief heads the 2nd and 3rd branches and the support corps (transport, medical services, supply, etc.).

In addition, the Inspectorate General of the Army (Γενική Επιθεώρηση Στρατού, ΓΕΠΣ) is a separate department with overarching authority.
