A recruit to the Imperial Guard had to pass a series of proficiency tests, varying in subjects and difficulty. Reportedly one of the prerequisites for initiation was to be able to recite one’s family history back for 23 generations from memory alone[citation needed].Imperial Guard units were distinguished by salmon (light red) coloured insignia. The Pahlavi Cavalry Guard had special blue and red ceremonial uniforms, including silver cuirasses and crested helmets.
