The Immortals was an elite cavalry unit of the army of the Sasanian Empire with the alleged size of 10,000 men, similar to the Achaemenid "Immortals" described by Herodotus. The name is derived from a term used by Roman historians to refer to the unit. Armenian and Islamic sources also have allusions to elite unit(s) in the Sasanian army.
