Argyraspides

The Argyraspides (Ancient Greek: Ἀργυράσπιδες, lit.'Silver Shields') were elite Macedonian soldiers who carried silver-plated shields, hence their name. The original unit were hypaspists serving in the army of Alexander the Great. During the Wars of the Diadochi, they initially served Eumenes, but betrayed him to Antigonus I Monophthalmus at the Battle of Gabiene in 316. After their dispersal under Antigonus, later units of the Seleucid Empire and Roman Empire would be modeled after them.
