That rung of officers who have come up the hard way, have very valuable experience, leadership skills beaten into them over years and years, a connecting tissue(and nerves too) between the feet-and-hands of the military unit and its head the commissioned officer.

JCO ranks are Naib Subedar, Subedar, and Subedar Major in the Army, and they carry one stripe, two stripes, and stripes plus an Ashoka emblem on their shoulders.
