Central Armed Police Forces (CAPF): Roles, Structure & UPSC Guide
Complete UPSC guide to the Central Armed Police Forces — CRPF, BSF, CISF, ITBP, SSB, Assam Rifles, their roles, jurisdictions, and place in India's internal security architecture.
The Central Armed Police Forces (CAPF) are seven paramilitary forces under the Ministry of Home Affairs (MHA), Government of India. Collectively numbering approximately 1 million personnel, they handle internal security, border management, industrial security, and special duties. The term “paramilitary forces” was officially replaced by “Central Armed Police Forces” in 2011 — though the older term is still widely used.
For UPSC, CAPF is essential in Polity, Internal Security (GS3), and defence.
What Are the CAPF?
Seven forces currently fall under CAPF:
| # | Force | Full Form | Primary Role | Personnel (approx.) |
|---|---|---|---|---|
| 1 | CRPF | Central Reserve Police Force | Internal security, anti-insurgency | ~325,000 |
| 2 | BSF | Border Security Force | India-Pakistan & India-Bangladesh borders | ~250,000 |
| 3 | CISF | Central Industrial Security Force | Industrial/strategic installations security | ~180,000 |
| 4 | ITBP | Indo-Tibetan Border Police | India-China border | ~90,000 |
| 5 | SSB | Sashastra Seema Bal | India-Nepal & India-Bhutan borders | ~90,000 |
| 6 | Assam Rifles | Assam Rifles | Northeast India security, India-Myanmar border | ~65,000 |
| 7 | NSG | National Security Guard | Counter-terrorism, VIP protection | ~7,500 |
Total CAPF strength: Approximately 1 million personnel.
Important note: Assam Rifles has a unique dual-control structure — under MHA administratively but under the Ministry of Defence (MoD) operationally. Some sources count only the first six as traditional CAPF.

Terminology
The term "paramilitary forces" traditionally included only:
- Assam Rifles
- Coast Guard
- Special Frontier Force (SFF)
The other forces (CRPF, BSF, CISF, ITBP, SSB) were central armed police forces. In 2011, the MHA renamed all seven forces collectively as Central Armed Police Forces (CAPF).
However, Assam Rifles and SFF are sometimes still called paramilitary forces in older literature.
Recruitment
Entry Levels
CAPF personnel are recruited through:
Directly to Officer Cadre:
- UPSC CAPF (AC) Exam (Assistant Commandants) — conducted by UPSC
- Eligibility: Graduate, age 20-25
- All seven CAPF forces except NSG recruit through this common exam
Directly to Constable Cadre:
- Staff Selection Commission (SSC) — Constable (GD) Exam
- Various age and educational qualifications
Lateral induction:
- Senior officers often from IPS or Army services (depending on the force)
NSG Recruitment
NSG is entirely drawn from Army and CAPF through deputation — no direct recruitment. Personnel serve 5-year tenures and then return to their parent unit.
Budgetary Position
CAPF budgetary allocation (2024-25 approximate):
- Total CAPF budget: ~Rs. 1.27 lakh crore
- Largest share: CRPF
- Major expenses: Salaries, training, weapons, vehicles, camp infrastructure
Challenges
Operational
- Stress and fatigue from prolonged postings in high-risk areas
- Casualties — especially in anti-Maoist operations
- Equipment gaps compared to the Army
- Delayed promotions and pay anomalies
Human Resources
- High suicide rate — among highest in Indian security forces (lifestyle, postings)
- Family separation — long postings away from home
- Transfer and promotion grievances
Political/Strategic
- AFSPA concerns in Northeast
- Central-state tensions over paramilitary deployment
- Internal security vs. external security tension (borders that should be Army but are CAPF)
