Formed in Athens in 1945 as the Higher Military Command of Attica (; Anotéra Stratiotikí Deíkisi Attikís, ASDA), by 1961 it had evolved from a territorial defence force to a Corps-sized formation, overseeing the Aegean region's four National Guard Commands.
In 1995, the command's headquarters were relocated to the suburb of Karea in Athens, Attica, and by 2005 it had become a major operational formation of the Hellenic Army, consisting of two division and five brigade-strength, mechanized, National Guard Battalion Higher Commands (; Anótati Deíkisi Tagmáton Ethnofylakís, ADTE) [REF].
