The
Hellenic National Defence General Staff (, abbr. ΓΕΕΘΑ) is the senior
staff of the
Hellenic Armed Forces. It was established in 1950, when the separate armed services ministries were consolidated into the
Ministry of National Defence. Its role in peacetime was as a coordinating and senior consultative body at the disposal of the Greek government, and in wartime as the overall headquarters of the Armed Forces. In recent years, through ongoing efforts at increased inter-services cooperation and integration, the HNDGS has assumed peacetime operational control over the separate branches. Between 19 December 1968 and 10 August 1977, the HNDGS was abolished, and the
Armed Forces Headquarters (Αρχηγείο Ενόπλων Δυνάμεων) established in its place.
