Pedites - Roman Infantry
Roman citizens between 17 and 46 could serve in the Roman legions as pedites (foot soldiers).
Roman Army
The legion was comprised of heavily armored foot soldiers who won battles because of their discipline, hard and efficient training, and the speed at which they learned new tactics. This site has small sections on each of the main parts of the Roman army.
