The umbrella term for the five armed central forces under the Ministry of Home Affairs, the Assam Rifles, and the National Security Guard, raised to assist in internal security, border guarding, and the protection of vital installations.
This is the single most directly relevant institutional topic for a CAPF aspirant: the names, full forms, ministry, and primary roles of the five forces are routinely tested and are the candidate's own future service.
The Army, Navy, and Air Force are the armed forces under the Ministry of Defence; the CAPFs are central police organisations under the Ministry of Home Affairs. "Paramilitary forces" in the strict current usage is reserved by some for the Assam Rifles, Coast Guard, and Special Frontier Force, but in common usage the term loosely covers the CAPFs.
Five CAPFs under the MHA: BSF, CRPF, CISF, ITBP, SSB; the CRPF is the largest.
