A hoplite was a heavily armed foot soldier of ancient Greece, particularly prominent in the city-states during the classical period. They typically fought in a phalanx formation, characterized by a tight, shielded line of soldiers. Hoplites were equipped with a helmet, breastplate, greaves, a shield (aspis), and a spear (dory), and their tactics emphasized discipline and collective strength in battle. The term "hoplite" derives from "hoplon," referring to the large round shield they carried.
