Central Armed Police Forces (CAPFs)
"Five central paramilitary forces under India's Ministry of Home Affairs — BSF, CRPF, CISF, ITBP, and SSB — responsible for border security, internal security, and industrial/critical infrastructure protection."
The Central Armed Police Forces (CAPFs) are five armed forces under the administrative control of the Ministry of Home Affairs (MHA), Government of India. They are distinct from the Indian Army (under Ministry of Defence) and from State Police forces. The five CAPFs and their primary mandates: 1. Border Security Force (BSF) — Act: 1968 - Guards India-Pakistan and India-Bangladesh land borders - ~2.65 lakh personnel; world's largest border guarding force - Also deployed for internal security, election duty, anti-smuggling 2. Central Reserve Police Force (CRPF) — Act: 1949 (oldest CAPF; pre-independence origins as Crown Representative's Police) - Primary internal security force: anti-insurgency, anti-Maoist operations (Operation Green Hunt) - ~3.25 lakh personnel; India's largest CAPF - Deployed in J&K, northeast, LWE-affected areas 3. Central Industrial Security Force (CISF) — Act: 1969 - Guards public sector undertakings, airports, ports, nuclear facilities, sensitive government installations - ~1.65 lakh personnel; also provides security to Delhi Metro 4. Indo-Tibetan Border Police (ITBP) — Act: 1992 (raised 1962, after Sino-Indian war) - Guards 3,488 km of India-China (Himalayan) border - Specialised in high-altitude operations; trained mountain troops - Also deployed for disaster relief in Himalayan states 5. Sashastra Seema Bal (SSB) — Act: 2007 (reoriented to border guarding 2001) - Guards India-Nepal (1,751 km) and India-Bhutan (699 km) borders - Also handles cross-border crime and smuggling Not CAPFs (common confusion): - National Security Guard (NSG): under MHA but counter-terrorism specialist; NSG Act 1986 — NOT a CAPF - Assam Rifles: administratively MHA but operationally under Army (Assam Rifles Act 2006) — NOT a CAPF - NIA, SPG, IB: investigative/intelligence agencies — not armed forces in the CAPF sense CAPF Act 2026: India's first umbrella administrative legislation covering all five CAPFs — harmonising service conditions, deputation norms, and disciplinary procedures without replacing individual force Acts.
High-frequency GS2 and GS3 Internal Security topic. Prelims: which forces are CAPFs; founding Acts and years; which forces are NOT CAPFs (NSG, Assam Rifles); MHA control. Mains: role of CAPFs in internal security; federal vs central policing; CAPF Act 2026 significance.

When the Supreme Court orders CAPF deployment for election duty in Manipur, it is the CRPF (internal security), BSF (border areas), CISF (sensitive installations), ITBP (Himalayan areas), and SSB (border districts) that are mobilised — all under a unified MHA command chain. The NSG (counter-terrorism specialists) would not be deployed for routine election duty.
