The Roman legion (from Latin legio, legionis, f., from lego, legere, legi, lectus — "to collect") was the basic military unit of the ancient Roman army. It consisted of a core of heavy infantry (legionaries), with auxiliary cavalry and ranged troops, typically skirmishers. The size of a typical legion varied widely throughout the history of ancient Rome, with complements ranging from 5000-6000 men in the republican period of Rome, to the fairly standard number of around 5,400 in the early and middle imperial period and finally to on average 1000-2000 men in the very late imperial period. As legions were not standing armies until the Marian reforms (c. 107 BC), and were instead created, used, and disbanded again, several hundred Legions were named and numbered throughout Roman history. To date, about 50 have been identified. In the time of the Roman Empire, there were usually about 28 standing Legions plus their Auxiliaries, with more raised as needed or as able.
Due to the enormous military successes of the Roman Republic and the Roman Empire the legion has long been regarded as the prime ancient model for military efficiency and ability.
