The Paramilitary and Central Armed Police Forces of India Explained

When people talk about the paramilitary forces of India, they usually mean the uniformed, armed organisations that guard the country’s borders, protect its critical installations and help the police keep order, without belonging to the Army, Navy or Air Force. Their jawans are seen at polling booths, airports, metro stations, flood-hit villages and remote Himalayan outposts, yet many people struggle to tell one force from another.

This explainer sorts that confusion out. It clarifies the official terminology, explains how these forces differ from the armed forces, and walks through the seven Central Armed Police Forces one by one, along with a few related forces that are often lumped in with them. It also covers how they are led, recruited and deployed. Last reviewed: 29 September 2026.

Paramilitary or CAPF? Getting the Terminology Right

“Paramilitary” is a popular label, not a legal one. In official documents the Government of India speaks of the Central Armed Police Forces, and the word “police” in that name matters. These are police organisations of the Union, armed and trained for demanding duties, and their personnel are governed by their own force-specific laws rather than the Army Act. The phrase “paramilitary forces of India” is nevertheless used constantly in newspapers and conversation, so it is worth knowing both terms.

Why the confusion exists

Historically, the word “paramilitary” was applied to any force organised on military lines but outside the regular army. Several Indian forces do look military: they use ranks, drill, battalions and heavy weapons, and some fight in counter-insurgency. Over time the media stretched the label to cover everything from border guards to factory security guards.

What the term does not include

• State police forces are run by state governments, because “police” and public order are State subjects under the Constitution.
• The Army, Navy and Air Force are the armed forces of the Union under the Ministry of Defence.
• The Indian Coast Guard is an armed force of the Union but sits under the Ministry of Defence, not the Home Ministry.
• Special Frontier Force and the Special Protection Group are separate, specialised organisations, discussed later.

Armed Forces vs Central Armed Police Forces

The clearest way to understand the paramilitary forces of India is to place them beside the military. The Constitution lets Parliament raise “any other armed forces of the Union” beyond the three services, and it also allows the Union to deploy its forces in a state in aid of the civil power. Article 355 adds the Union’s duty to protect every state against external aggression and internal disturbance. The CAPFs are the everyday instrument of that duty.

The Army does hold the Line of Control and the Siachen Glacier, while the CAPFs hold most other international borders. The two systems cooperate closely, and in some regions the CAPFs work under the operational command of the Army.

The Seven Central Armed Police Forces at a Glance

The table below lists each force with its founding year, main role and area of responsibility. Only well-established founding years are shown.

A useful shortcut is to think of four “border” forces (BSF, ITBP, SSB and Assam Rifles) and three “internal” forces (CRPF, CISF and NSG). The next sections explain each of them.

Internal Security Forces: CRPF, CISF and NSG

Three of the seven forces have no frontier to hold. They work inside the country, supporting the police, protecting infrastructure and responding to terrorism.

Central Reserve Police Force (CRPF): The Internal Security Backbone

The CRPF is the largest of the CAPFs and the one most Indians encounter in daily life. It began in 1939 as the Crown Representative’s Police, formed to support princely states during the colonial period, and was renamed the Central Reserve Police Force after Independence under the CRPF Act of 1949.

Roles and specialised units

• Internal security: supporting state police in maintaining public order and handling civil disturbances.
• Counter-insurgency: operating in Jammu and Kashmir, the Northeast and areas affected by Left Wing Extremism.
• Election duty: escorting polling parties and securing polling stations when the Election Commission requests central forces.
• Rapid Action Force (RAF): a wing created in the early 1990s and trained for riot control and crowd management.
• CoBRA: a specialised jungle-warfare unit raised in the late 2000s for anti-Naxal operations.

Historic moments

Two episodes are remembered in the force’s history. In October 1959, a CRPF patrol was ambushed by Chinese troops at Hot Springs in Ladakh, and 21 October is observed every year as Police Commemoration Day. In April 1965, CRPF personnel repulsed a Pakistani attack at Sardar Post in the Rann of Kutch, an event commemorated as Valour Day. The force has also contributed all-women contingents to United Nations missions.

Central Industrial Security Force (CISF): Protecting Infrastructure

Unlike the border forces, the CISF faces no frontier. It was established in 1969, after Parliament passed the CISF Act of 1968, to provide security cover to public sector undertakings. Its role has expanded a great deal since then, and the force is now among the most visible in India’s cities.

Where you see the CISF

• Airports: security screening and protection of civil aviation facilities.
• Metro rail systems in several cities.
• Nuclear, space and power installations and other strategic sites.
• Ports, mines and steel plants, along with government buildings and some heritage monuments.

Additional functions

The CISF also maintains a fire service wing that responds to emergencies in industrial complexes, and it offers security consultancy to private and public organisations. Its motto is “Protection and Security”. Although it is often thought of as a static guarding force, its personnel undergo commando-style training and are also deployed for internal security when required.

National Security Guard (NSG): The Black Cats

The NSG is India’s elite counter-terrorism force. It was raised in 1984 after the events of that year highlighted the need for a highly trained federal unit capable of tackling terrorism, and it was formally established through the National Security Guard Act of 1986. Its members wear black uniforms and are widely known as the “Black Cats”.

Structure

The NSG has two main elements. The Special Action Group is drawn largely from the Army, while the Special Rangers Group draws from other central and state forces. Their operational hub is at Manesar in Haryana, with regional hubs in major cities so that teams can reach a crisis quickly.

Notable operations

• Operation Black Thunder (1988): flushing out militants from the Golden Temple complex in Amritsar.
• Operation Vajra Shakti (2002): responding to the attack on the Akshardham temple in Gandhinagar.
• Operation Black Tornado (2008): the response to the 26/11 Mumbai attacks.

The NSG’s motto is “Sarvatra Sarvottam Suraksha”, meaning the best security everywhere. Its skills include hostage rescue, bomb disposal, anti-hijacking and urban combat.

Border-Guarding Forces: BSF, ITBP, SSB and Assam Rifles

The other four forces are organised by border, and the principle followed is generally one border, one force. That keeps responsibility clear and lets each force build expertise in its own terrain.

Border Security Force (BSF): The First Line of Defence

The BSF was raised in 1965, after the Indo-Pak conflict of that year exposed the need for a dedicated, professionally trained border force under central control. It is often described as India’s “First Line of Defence”, and its motto is “Duty unto Death”.

Where it stands guard

The BSF guards the India-Pakistan border, including the international boundary in Jammu, Punjab, Rajasthan and Gujarat, and the long India-Bangladesh border across West Bengal, Assam, Meghalaya, Tripura and Mizoram. Terrain ranges from desert and marshland to riverine areas and dense forest.

What makes it distinctive

• It has its own water wing for patrolling creeks and rivers, an air wing and an artillery component, unusual for a police force.
• Its camel contingent is a popular sight at the Republic Day parade, and its Retreat Ceremony at Attari-Wagah draws large crowds.
• During the 1971 Bangladesh Liberation War, the BSF worked alongside the Army on the eastern front.
• Its main peacetime tasks are preventing infiltration, smuggling and other trans-border crime.

ITBP and SSB: Guarding the Himalayan and Open Borders

Two forces watch the borders to India’s north and east, and they were both born from lessons learnt in the early 1960s.

Indo-Tibetan Border Police (ITBP)

Raised in 1962, in the wake of the India-China war, the ITBP guards the India-China border, which runs through some of the world’s most extreme terrain. Its border outposts are located at very high altitudes, often in freezing conditions and reachable only by foot or by air. Personnel are trained in mountaineering, skiing and survival, and are sometimes called “Himveers”. Apart from border duties, the force helps pilgrims on the Kailash Mansarovar Yatra and provides rescue support in the mountains.

Sashastra Seema Bal (SSB)

The SSB began in 1963 as the Special Service Bureau, focused on building resistance and morale in border populations. Following a review of national security after the Kargil conflict, it was reorganised, renamed Sashastra Seema Bal in 2001 and given charge of the borders with Nepal and Bhutan. These are open borders that allow free movement of people under friendship treaties, so the SSB’s job is less about fences and more about intelligence, community engagement and checking cross-border crime. The force has also been used for anti-Naxal duties and election security.

Assam Rifles: Sentinels of the Northeast

The Assam Rifles is the oldest of the CAPFs. It traces its beginnings to the Cachar Levy, raised in 1835 to protect British tea estates and settlements in the Northeast, and it later served in the First World War and other campaigns. Today it guards the India-Myanmar border and supports counter-insurgency across the region. Because of the close links it has built with hill communities, it is often called the “Friends of the Hill People”.

A unique dual control

The Assam Rifles is the only CAPF with a dual system of command. It is administered by the Ministry of Home Affairs, which handles its pay, allowances and infrastructure, but its operational control rests with the Indian Army. Its Director General is normally a serving Army officer, and many of its senior officers come to the force on deputation from the Army. This arrangement explains why it is a standing example of cooperation between the military and the police in the Northeast.

Beyond the border

• Manning border posts along the frontier with Myanmar, including the Free Movement Regime areas that link border communities.
• Providing relief and medical help in remote regions.
• Supporting the civil administration in conflict-affected districts of Manipur, Nagaland, Mizoram and Arunachal Pradesh.

Related Forces That Are Not CAPFs

Several other organisations are often placed under the “paramilitary” label. It helps to know how they differ.

• Special Frontier Force (SFF): raised in 1962 after the India-China war, it is a covert special force operating under the Cabinet Secretariat. It is not part of the seven CAPFs.
• Special Protection Group (SPG): created in 1985 through a separate law, it exists only to protect the Prime Minister and certain designated persons. Its purpose is close protection, not general security.
• Indian Coast Guard: established in the late 1970s under the Coast Guard Act, it protects India’s maritime zones, prevents smuggling and conducts search and rescue at sea. It is an armed force of the Union under the Ministry of Defence.
• State armed police: forces such as the Provincial Armed Constabulary and India Reserve Battalions are raised by states, not the Centre.
• Railway Protection Force: an armed force of the Union under the Ministry of Railways that protects railway property and passengers.

Command, Leadership and Legal Framework

Each of the paramilitary forces of India has its own statute. Among them are the CRPF Act 1949, the BSF and CISF Acts of 1968, the ITBP Force Act 1992, the NSG Act 1986, the Assam Rifles Act 2006 and the SSB Act 2007. These laws define discipline, powers and service conditions.

Who leads them

The Director General of a force is usually an officer of the Indian Police Service, appointed by the Government of India. Below the Director General are Additional Directors General, Inspectors General (heading a frontier or sector), Deputy Inspectors General (heading a range) and Commandants, who lead battalions. The typical unit structure is the battalion, made up of companies that in turn contain platoons and sections.

Deployment

The MHA decides where companies are placed. States may request central forces when they need extra strength, and the Election Commission requests them for polls. Once a company arrives, it usually works with the local police, while the state administration continues to be responsible for public order.

Recruitment and Careers

Entry into the CAPFs occurs at several levels, and each has its own examination.

• Officers: Assistant Commandants (Group A) are recruited through an examination conducted by the Union Public Service Commission. Senior posts are filled by promotion and, in the case of the Director General and some senior ranks, by deputation of IPS officers.
• Constables and Riflemen: the Staff Selection Commission conducts a general duty constable examination for CAPFs and the Assam Rifles.
• Sub-inspectors and other ranks: filled through combined examinations followed by physical standard tests, physical efficiency tests and medical checks.
• Specialists: doctors, engineers, radio operators and other tradespeople are hired for technical roles.

Recruits go through rigorous training at force academies and centres. Officers commonly train at institutions such as the Sardar Vallabhbhai Patel National Police Academy in Hyderabad or at force-specific training schools. Many forces have also opened doors to women through dedicated battalions and general induction into combat roles.

Beyond Guarding: Disasters, Elections and the United Nations

The work of these forces extends well beyond patrols and checkpoints.

Disaster response

The National Disaster Response Force (NDRF), created under the Disaster Management Act of 2005 and formed in 2006, has its battalions drawn from the BSF, CRPF, CISF, ITBP and SSB. Its teams rush to floods, cyclones, earthquakes and building collapses, and are trained in search, rescue and chemical, biological and nuclear emergencies. The ITBP is also known for mountain rescue during Himalayan disasters.

Elections and public order

During large elections, thousands of companies of central forces are moved across states to help ensure free and fair polling. They are a neutral presence that supports the state police.

United Nations missions

Indian police personnel, many from central forces, have served in UN peacekeeping missions. In 2007 an all-women formed police unit, largely drawn from the CRPF, was sent to Liberia, the first of its kind in the world.

Conclusion

The paramilitary forces of India form a layered security architecture that sits between the military and the civil police. The Army, Navy and Air Force defend the nation against external threats, while the seven Central Armed Police Forces watch the borders, protect critical installations, support the police and respond to crises. Knowing which force does what, and under which ministry, makes news reports about deployments and operations much easier to follow.

Frequently Asked Questions

What is the difference between paramilitary forces and the armed forces in India?

The armed forces are the Army, Navy and Air Force, run by the Ministry of Defence to defend the country from external threats. The paramilitary forces, officially called Central Armed Police Forces, are under the Ministry of Home Affairs and focus on border management, internal security and protecting key installations.

How many Central Armed Police Forces are there in India?

There are seven: Assam Rifles, Border Security Force, Central Industrial Security Force, Central Reserve Police Force, Indo-Tibetan Border Police, National Security Guard and Sashastra Seema Bal. Other organisations such as the Special Frontier Force and the Indian Coast Guard are not counted among them.

Which is the largest paramilitary force in India?

The Central Reserve Police Force is generally regarded as the largest of the Central Armed Police Forces. Raised in 1939, it handles internal security duties, counter-insurgency, election duty and riot control across the country.

Which paramilitary force guards which border?

The BSF guards the borders with Pakistan and Bangladesh, the ITBP guards the border with China, the SSB guards the borders with Nepal and Bhutan, and the Assam Rifles guards the border with Myanmar. The Army holds the Line of Control, and the Coast Guard patrols the seas.

Why is the Assam Rifles different from other paramilitary forces?

The Assam Rifles is the oldest of the forces, tracing its origin to 1835. It is administered by the Ministry of Home Affairs but is under the operational control of the Indian Army, and it is usually led by an Army officer.

Are the NSG and the SPG the same?

No. The NSG, or Black Cats, is a counter-terrorism force raised in 1984 that responds to hijackings, hostage crises and terrorist attacks. The SPG was created in 1985 to provide close protection to the Prime Minister and certain other designated persons, and it is a separate organisation.
