Greek armor, primarily used from the 8th to the 4th century BCE, was designed for protection in battle. The most common type was the hoplite armor, which included a bronze breastplate, a helmet, and greaves to protect the legs. This armor was often complemented by a large round shield called a hoplon, which provided additional defense. The design of Greek armor varied by region and period, but it typically emphasized mobility and protection. The phalanx formation, a key military tactic, relied on heavily armored soldiers working together, showcasing the importance of armor in ancient Greek warfare.
