immortals

The Immortals (Ancient Greek: Ἀθάνατοι Athánatoi) also known as the Persian Immortals was the name given by Herodotus to an elite heavily-armed infantry queued unit of 10,000 soldiers in the army of the Achaemenid Empire. This force performed the dual roles of both Imperial Guard and standing army. The force consisted mainly of Persians, but also included Medes and Elamites. Essential questions regarding the unit remain unanswered, because authoritative sources are missing.
