In 1953 the unit was expanded in size to a division under General Teymur Bakhtiar. In 1972 the Lashkari Guard Division was incorporated in the Imperial Guard together with a Conscript Brigade, expanding the Guard to a full corps of two divisions. The core of the Imperial Guard was the all volunteer Javidan Guard (Gârd e Jâvidân, Persian: Immortal Guard), better known as the “Immortals” after the ancient Persian royal guard or Persian Immortals.
