They were super-heavy cavalry, with both men and horses armoured from head to toe. They were elite shock troops, intended to close in as fast as possible and wear down the enemy with powerful lance charges and and brutal melee attacks.
Historically a force of 10,000 men, they were an elite within the Sassanian army. Only few selected Savaran veterans, who had proved them exceptionally in battle, were allowed to join the Zhayedan. Their task was to secure any breakthrough, and they were often held as reserve force, entering the battle at crucial stages.
They were a revival of the Achaemenid Immortals and so it was highly probably that their uniforms, organization and insignia reflected Achaemenid tradition. The Achaemenid organized their Immortals in 10 regiments of 1,000 warriors each. Each had its own primary colour. So there were the Yellow, the Blue and the Red regiments among the most known. The Zâyedân-i-Zarrin were the Zhayedan of the Golden Regiment.
Their commander bore the title of Varthragh-Nighan Khvadhay and often was a Prince of the Royal family. The Zâyedân belonged to the Clibinarii cavalry, man and horse were completely armoured.
