The Hellenic Army, formed in 1828, is the land force of Greece. The term Hellenic is the endogenous synonym for Greek. The Hellenic Army is the largest of the three branches of the Hellenic Armed Forces, also constituted by the Hellenic Air Force (HAF) and the Hellenic Navy (HN). The army is commanded by the chief of the Hellenic Army General Staff (HAGS), which in turn is under the command of Hellenic National Defence General Staff (HNDGS). 

The main missions of the Hellenic Army are the defence of the state's independence and integrity, the safeguarding of national territory, and the decisive contribution to the achievement of the country's policy objectives.

During peacetime, the Army has the following main objectives:

• The maintenance of high operational readiness for the prevention and effective confrontation of dangers and threats, as well as the ensuring of rapid response capability.

• The contribution to international security and peace.

• The contribution to activities of social aid and the support of state services for the confrontation of emergency situations.

After a major reorganization which occurred in the last decade, which included the transformation of most Infantry formations into Mechanized Brigades and a parallel reduction of personnel, the Hellenic Army's higher command is the Hellenic Army General Staff.

There are four major military commands which supervise all army units,

• 1st Army, based at Larissa, that includes the IV Army Corps, responsible for the defence of the northern and eastern borders.

• Supreme Military Command of the Interior and Islands, based at Athens with the mission to provide cover for the islands in the Aegean Sea.

• Supreme Military Support Command undertaking various logistics and organizational tasks.

• NATO Deployable Corps, based at Thessaloniki, Macedonia

Although divisions still exist, having the role of forward commands, the Army is mainly organized in brigades, that follow the typical NATO standards consisting of five battalions, three manoeuvre, one artillery, one support and some other company sized formations. According to the latest developments, up to 2015, all active divisions will dissolve, but all brigades will acquire one more manoeuvre battalion, largely eliminating the distinction between mechanized and armoured formations, thus creating a new type brigade, which will be named Strike Brigade.
