Junior Commissioned Officer (JCO) is a rank category specific to the Indian Army. The Central Industrial Security Force (CISF), like other Central Armed Police Forces (CAPFs), uses rank structures typically categorized into Gazetted Officers, Subordinate Officers, and Enrolled Members (Other Ranks).
JCO ranks are part of the Indian Army’s structure, not standard in CAPFs like CISF.
Subordinate Officers in CISF include ranks like Inspector, Sub-Inspector, and Assistant Sub-Inspector. Supervisory Officers typically refers to the Gazetted Officers. “Under Officers” is not a recognized category name in the CISF rank structure.
