The term has been used since the times of Ancient Greece to describe the commanding officer of a lokhos (company). The average lokhos of the time numbered a hundred men. The order of the rank in the military command chain differed from city-state to city-state. For example, Xenophon reported that a lokhagos of Sparta served under a polemarch. Aristotle reported that his counterpart in Athens served under a taxiarhos.
The rank of lokhagos was roughly equivalent to that a Roman army centurion. The term was however also used by later writers to describe the civilian leader of a curia. The rank was still in use in the military of the Byzantine Empire.
In the modern Hellenic Army the rank is superior to an Ypolokhagos (First Lieutenant) and inferior to an Tagmatarhis (Major). The insignia consists of three silver stars. Officers holding this rank should be addressed as "Kyrie Lokhage" (Κύριε λοχαγέ) (stressed on the last syllable) by their subordinates, or "Lokhage + family name" by their superior officers.
