The Hook: The Review After Kargil
After the 1999 Kargil conflict, the government set up the Kargil Review Committee under strategic analyst K. Subrahmanyam. Its report pointed to serious gaps in intelligence collection, sharing and assessment. A Group of Ministers then reviewed the entire national security system in 2001, leading to new bodies such as the Defence Intelligence Agency, the NTRO, the Multi-Agency Centre and the “one border, one force” principle.
The exercise posed the question that runs through this chapter: India has many capable forces and agencies — but who coordinates them, and is each one doing the job it was built for?

- Army, Navy and Air Force — external defence; deployed internally only in aid of civil power (Union List Entry 2A) or under AFSPA in disturbed areas.
- Chief of Defence Staff (CDS) — post created with effect from 1 January 2020; heads the Department of Military Affairs, is the Permanent Chairman of the Chiefs of Staff Committee, and is the principal military adviser to the Defence Minister on tri-service matters. Recommended in various forms by the GoM (2001), the Naresh Chandra Task Force (2012) and the Shekatkar Committee (2016).
- Indian Coast Guard — under the Ministry of Defence; Coast Guard Act, 1978.
Central Armed Police Forces (Ministry of Home Affairs)
The MHA uses “CAPFs” for seven forces.
| Force | Raised | Primary mandate |
|---|---|---|
| Assam Rifles | 1835 (as the Cachar Levy) | Oldest central paramilitary force; guards the Myanmar border; counter-insurgency in the North-East. Dual control: administrative — MHA; operational — Army |
| Border Security Force (BSF) | 1965 | Guards Pakistan and Bangladesh borders; on the LoC under Army’s operational control |
| Central Reserve Police Force (CRPF) | 1939 (as Crown Representative’s Police; renamed by the CRPF Act, 1949) | Largest CAPF; internal security, counter-insurgency, LWE operations, elections. Specialised units: Rapid Action Force (1992, riots and communal violence) and CoBRA (2008, jungle warfare against LWE) |
| Central Industrial Security Force (CISF) | 1969 | Security of public sector undertakings, airports, metro systems, sensitive government buildings; also offers consultancy to private industry |
| Indo-Tibetan Border Police (ITBP) | 1962 | Guards the China border (LAC); high-altitude specialist; disaster response in the Himalaya |
| National Security Guard (NSG) | 1984 (NSG Act, 1986) | Federal contingency force for counter-terrorism and counter-hijacking; “Black Cats”; regional hubs set up after 26/11 |
| Sashastra Seema Bal (SSB) | 1963 (as Special Service Bureau; renamed 2003) | Guards Nepal (2001) and Bhutan (2004) borders |
The deployment debate. Because public order is a State subject, States frequently request CAPFs for law and order, elections and LWE operations. Critics, including parliamentary committees, have pointed out that border-guarding forces are often diverted from their primary role, affecting training and morale, and that States under-invest in their own police as a result.
Intelligence agencies
| Agency | Year | Under | Mandate |
|---|---|---|---|
| Intelligence Bureau (IB) | Origins in 1887 (Central Special Branch) | MHA | Domestic intelligence and counter-intelligence; runs the Multi-Agency Centre (MAC) for real-time sharing of terror-related intelligence |
| Research and Analysis Wing (R&AW) | 1968 | Cabinet Secretariat | External intelligence |
| National Technical Research Organisation (NTRO) | 2004 | National Security Adviser | Technical intelligence (signals, imagery, cyber); parent of NCIIPC |
| Defence Intelligence Agency (DIA) | 2002 | Ministry of Defence | Coordinates intelligence of the three services |
| NATGRID | Conceived after 26/11 | MHA | Links databases (travel, banking, telecom, immigration and others) for authorised agencies |
None of IB, R&AW or NTRO is created by a statute; they function under executive orders, which raises a recurring Mains theme — parliamentary oversight and accountability of intelligence agencies.
The proposed National Counter Terrorism Centre (NCTC) (2012) was not set up, after several States objected that its powers would infringe on their policing authority.
Investigation and enforcement agencies
| Agency | Basis | Under | Mandate |
|---|---|---|---|
| CBI | Executive resolution (1963); powers from the Delhi Special Police Establishment Act, 1946 | DoPT (Ministry of Personnel) | Corruption, economic and special crimes; needs State consent (Section 6, DSPE Act) to investigate in a State |
| NIA | NIA Act, 2008 | MHA | Terrorism and other scheduled offences; no State consent needed |
| Narcotics Control Bureau (NCB) | 1986, under the NDPS Act, 1985 | MHA | Coordination of drug law enforcement |
| Enforcement Directorate (ED) | 1956 (origins) | Department of Revenue | PMLA, FEMA, FEOA |
| Directorate of Revenue Intelligence (DRI) | 1957 | CBIC, Department of Revenue | Smuggling, customs fraud |
Coordination: the National Security Council system
| Body | Role |
|---|---|
| National Security Council (NSC) — set up 1998, chaired by the Prime Minister | Apex advisory body on national security |
| National Security Adviser (NSA) | Chief adviser to the PM on national security; heads the NSCS |
| National Security Council Secretariat (NSCS) | Secretariat; home of the National Cyber Security Coordinator |
| Strategic Policy Group | Inter-ministerial body for policy coordination |
| National Security Advisory Board | Non-government experts providing long-term analysis |
Police and police reform
- Police and public order are in the State List (Entries 1 and 2), so the State police are the first responders to almost every internal security threat.
- Prakash Singh v. Union of India (2006) — the Supreme Court issued seven directions:
- State Security Commission to insulate police from undue political pressure.
- DGP selected from among officers empanelled by the UPSC, with a minimum tenure of two years.
- Minimum tenure of two years for IGs, SPs and SHOs in operational posts.
- Separation of investigation from law-and-order functions.
- Police Establishment Board for transfers and postings.
- Police Complaints Authority at State and district levels.
- National Security Commission at the Union level for selection of chiefs of CAPFs.
- The Model Police Act, 2006 (drafted by a committee chaired by Soli Sorabjee) and the 2nd ARC’s 5th Report, Public Order (2007) carry similar recommendations. Implementation by States has been uneven.
Memory Anchors
Seven CAPFs — “A Big Cat Can Instantly Notice Snakes”: Assam Rifles · BSF · CISF · CRPF · ITBP · NSG · SSB.
Raising order (oldest first): Assam Rifles (1835) → CRPF (1939) → ITBP (1962) → SSB (1963) → BSF (1965) → CISF (1969) → NSG (1984).
Prakash Singh’s seven — “S-D-T-S-E-C-N”: State Security Commission · DGP tenure · Tenure for field officers · Separation of investigation · Establishment Board · Complaints Authority · National Security Commission.
For Prelims
- Assam Rifles is the oldest central paramilitary force (1835); it is under dual control — MHA (administrative) and Army (operational).
- CRPF is the largest CAPF; RAF (1992) and CoBRA (2008) are its specialised units.
- NSG was raised in 1984 and governed by the NSG Act, 1986.
- R&AW (1968) is under the Cabinet Secretariat, not the MHA or MoD.
- CBI derives its powers from the DSPE Act, 1946 and functions under the DoPT.
- The CDS post took effect on 1 January 2020.
- The NSC was set up in 1998 and is chaired by the Prime Minister.
For Mains
- Dimensions:
- Institutional: multiplicity of agencies, turf battles, overlapping mandates.
- Federal: police as a State subject versus central agencies (NIA, CBI consent, NCTC debate).
- Operational: over-deployment of CAPFs, training gaps, vacancies, stress and morale.
- Accountability: intelligence agencies without statutory basis or parliamentary oversight; police complaints mechanisms.
- Reform: jointness and theatre commands, intelligence fusion, police modernisation.
- Keywords: jointness, intelligence fusion, actionable intelligence, force multiplier, federal contingency force, police–public interface, SMART policing.
- Value-addition: Kargil Review Committee (1999); GoM (2001); Naresh Chandra Task Force (2012); Shekatkar Committee (2016); Prakash Singh (2006); Model Police Act (2006); 2nd ARC 5th and 8th Reports.

Practice
Prelims
Which one of the following statements about the Assam Rifles is correct?
Solution
Assam Rifles is under dual control — administrative (MHA) and operational (Army). It guards the Myanmar border (Nepal is SSB’s), and it was raised in 1835, making it the oldest central paramilitary force. ITBP and SSB are the forces raised after the 1962 war.
Answer: B
Consider the following statements:
- The Research and Analysis Wing functions under the Cabinet Secretariat.
- The Central Bureau of Investigation derives its legal powers from the Delhi Special Police Establishment Act, 1946.
- The National Security Guard is governed by an Act of Parliament.
Which of the statements given above is/are correct?
Solution
All three are correct. R&AW (1968) is under the Cabinet Secretariat; the CBI’s powers flow from the DSPE Act, 1946; the NSG is governed by the NSG Act, 1986.
Answer: D
Which of the following were among the directions of the Supreme Court in Prakash Singh v. Union of India (2006)?
- Setting up a State Security Commission
- Separation of investigation from law-and-order functions of the police
- Setting up a Police Complaints Authority
- Bringing police into the Concurrent List
How many of the above are correct?
Solution
Items 1, 2 and 3 were among the seven directions. Item 4 is wrong — the Court cannot amend the Seventh Schedule; police remains a State List subject. Moving police to the Concurrent List has been suggested in public debate but was not a direction.
Answer: C
Mains
“India does not lack security agencies; it lacks coordination among them.” Examine this statement with reference to the mandates of various security forces and agencies, and suggest reforms.
Solution
Introduction: India’s security architecture spans the armed forces (MoD), seven CAPFs (MHA), State police, intelligence agencies (IB, R&AW, NTRO, DIA) and investigation bodies (NIA, CBI, NCB, ED). The Kargil Review Committee (1999) and the 26/11 attacks (2008) both exposed coordination failures rather than lack of capacity.
Body:
- Mandates: armed forces — external defence and aid to civil power; CAPFs — border guarding (BSF, ITBP, SSB, AR), internal security (CRPF), industrial security (CISF), counter-terror (NSG); intelligence — domestic (IB), external (R&AW), technical (NTRO); investigation — terror (NIA), corruption (CBI).
- Coordination gaps: intelligence not shared in time (Multi-Agency Centre created and strengthened in response); centre–State friction (CBI consent, NCTC proposal dropped in 2012); CAPFs diverted from primary roles; tri-service jointness historically weak.
- Reforms so far: NSC system (1998); DIA, NTRO, MAC (2001–04); NIA (2008); NSG hubs; CDS and Department of Military Affairs (2020); NATGRID.
- Further reforms: legislative basis and oversight for intelligence agencies; implementation of Prakash Singh directions; State police capacity so CAPFs return to core roles; theatre commands; common databases and secure communication; regular joint exercises.
Conclusion: The statement is largely valid. Capacity has grown, but security outcomes depend on fusion — of intelligence, of commands and of Centre–State effort.
Quick Revision
| Point | One-liner |
|---|---|
| CAPFs | Seven — AR, BSF, CISF, CRPF, ITBP, NSG, SSB (MHA) |
| Oldest / largest | Assam Rifles (1835) / CRPF |
| CRPF units | RAF (1992), CoBRA (2008) |
| NSG | 1984; NSG Act 1986; counter-terror and counter-hijack |
| Intelligence | IB (MHA), R&AW (Cabinet Sectt, 1968), NTRO (2004), DIA (2002) |
| CBI | 1963 resolution; DSPE Act 1946; DoPT; State consent needed |
| CDS | 1 January 2020; Department of Military Affairs |
| NSC | 1998; chaired by PM |
| Police reform | Prakash Singh (2006) — seven directions |
Key Takeaways
- Know the map: which force or agency, under which ministry, for which mandate.
- Coordination — not capacity — is the recurring weakness, from Kargil to 26/11; most reforms since 2001 target it.
- Police are the first responders but a State subject; police reform is therefore central to internal security.
