A brigade is three battalions plus supporting arms under a Brigadier. A battalion is four companies under a Colonel. Those two sentences answer most questions about this rung of the Army, but the marks are lost on a third word, regiment, which means a different thing in the infantry than it does in the armour and the artillery.
This page sits under our Indian Army hierarchy section and the Indian Army hub. The ladder is on the hierarchy page and the rung above is on our divisions page, so here we go inside: brigade types, how a unit is named, the regiment trap, and how the Rashtriya Rifles, Territorial Army, Rudra and Bhairav fit in.
The Brigade: Three Battalions Under a Brigadier
The NIOS military studies text says three battalions form a brigade, commanded by a Brigadier. Around the battalions sit the arms and services a brigade needs to work alone: artillery, engineers, signals, supply, repair and medical cover. PIB career notes name its senior staff post, the Brigade Major. A brigade is the lowest rung that mixes arms.
How big is it? The Army publishes no strength table. Our hierarchy page gives a rule-of-thumb range of 3,000 to 5,000, and The Tribune (27 Jul 2025) put a traditional brigade at about 3,000 troops. Both are outside figures. The safe learning is the ratio and the rank: a Brigadier is a one-star officer, the equivalent of a Commodore in the Navy and an Air Commodore in the Air Force (see rank equivalence).
Most brigades sit inside a division. Some are independent: PIB writes them as "(Independent)" or "(I)" in the name, as in 9 (Independent) Mountain Brigade Group, and they stand outside a division.
Brigade Types in One Table
Brigades are named for what they are built around. The Army has published no full list, so the table shows only types we found in PIB, with PIB's own example.
| Type | Built around | Example in PIB |
|---|---|---|
| Infantry brigade | Three infantry battalions with supporting arms; the standard all-round brigade | 168 Infantry Brigade, Jammu and Kashmir (PIB career note, May 2026) |
| Mountain brigade | Mountain-trained battalions for high ground where roads are few | 63 Mountain Brigade (PIB, Jan 2024); 9 (Independent) Mountain Brigade Group (PIB, Jan 2026) |
| Armoured brigade | Tank regiments, with mechanised infantry in support | "Independent Armoured Brigade" appears in several PIB career notes for Army commanders |
| Mechanised brigade | Infantry in tracked vehicles beside tanks | 340 (I) Mechanised Brigade (PIB, Exercise Bold Kurukshetra, Jul 2025) |
| Artillery brigade | Gun and missile regiments for massed fire | Tanda Artillery Brigade, Akhnoor (PIB, Jan 2025) |
| Engineer brigade | Engineer regiments for bridging, mine-clearing and obstacles | 474 Engineer Brigade (PIB, Feb 2024) |
| Air defence brigade | Army air defence regiments | 616 (Independent) Air Defence Brigade (PIB, Aug 2025) |
| Parachute (airborne) brigade | Paratroop battalions able to be dropped from the air | 50 (Independent) Parachute Brigade, Agra (PIB, Aug 2025) |
| Rudra brigade | All arms under one commander: infantry, mechanised infantry, armour, artillery, Special Forces and drones (as The Tribune reported on 27 Jul 2025; PIB says "all arms") | PIB, 26 Jul 2025; a Rudra Brigade in Exercise Akhand Prahaar, Nov 2025 |
| Electronic warfare brigade | Units for jamming and electronic support | Listed among reforms progressed (PIB, 30 Jun 2026) |
We found no published Special Forces brigade. The Special Forces are battalions of the Parachute Regiment, covered below and on our special forces page; the airborne brigade at Agra is not the same thing.
Rudra. On 26 July 2025, the 26th Kargil Vijay Diwas, the Army chief named Rudra all-arms brigades among the Army's reforms (PIB). Older brigades are arm-specific; a Rudra brings several arms under one commander. PIB gives no count, so learn the name and the rung. The divisions page covers the related Integrated Battle Group.
The Battalion: Colonel, Companies and the CO
The battalion is the infantry's main fighting unit. The NIOS text gives four companies to a battalion and a Colonel as its commander, called the Commanding Officer (CO). Public descriptions add a support company (heavier weapons) and a headquarters company. The Army publishes no establishment table; books quote roughly 800 to 1,000 soldiers, and we found no official figure.
Older books give a Lieutenant Colonel as the CO, and PIB's account of Rezang La in 1962 names a Lieutenant Colonel. Present-day textbooks, including NIOS, say Colonel. The Colonel is the answer for today's organisation.
The other arms use their own words at the same rung. PIB career notes speak of commanding an Armoured Regiment or a Field Regiment before commanding a brigade, so a regiment in the armour or the artillery is a unit at the same rung as a battalion. In an armoured regiment the commander is called the Commandant: PIB's note on a former Army chief says he "assumed command of the Regiment ... as its second Commandant". The combat arms and services pages cover the arms behind each word.
The Big Trap: Battalion Versus Regiment
In the infantry, a regiment is the parent family, not a unit that fights and not a formation that sits on the ladder. A battalion is the unit that fights. Think of the Sikh Regiment as a family and each of its numbered battalions as one of its children.

| Word | In the infantry | In the Armoured Corps and artillery |
|---|---|---|
| Regiment | The parent family (Sikh Regiment, Kumaon Regiment, Rajputana Rifles, Gorkha Rifles) with a Regimental Centre that trains recruits; commands no field force | A battalion-sized unit (66 Armoured Regiment, a Field Regiment) |
| Battalion | The unit that fights; posted to a brigade | Not used; the word is "regiment" |
| Regimental Centre | Recruits and trains for the regiment; the family's home | The armour and artillery have their own centres and schools |
The regiment runs the family: PIB records Agniveers training at 40 Regimental Centres and Training Centres (Dec 2023), and the President's Colours presented to the Third Battalion of the Naga Regiment at the Kumaon Regimental Centre, Ranikhet (Oct 2023). The battalion serves. It is posted to a brigade, can be re-posted to another, and the regiment's name on its title never changes. A brigade therefore holds battalions of different regiments: one Sikh, one Rajputana Rifles, one Gorkha.
How units are named. PIB writes the number first, then the regiment, as in 13 KUMAON (13th Battalion, Kumaon Regiment), 21 RAJPUT, 13 SIKH LI (Sikh Light Infantry), 12 DOGRA, 21 GRENADIERS and 2 MAHAR. A recent PIB career note says an officer was commissioned into "the 8th Battalion of the Garhwal Rifles".
The Gorkha Rifles number their regiments, so they need two numbers: battalion first, regiment second. PIB uses 1/11 Gorkha Rifles (1st Battalion, 11th Gorkha Rifles), 5/9 GR, 7/8 GR and 4/5 GR (FF), where FF is Frontier Force. The Indian Army's Gorkha regiments are 1, 3, 4, 5, 8, 9 and 11 GR (the Army's infantry page). Our regiments page lists the families, and mottos and war cries gives each one's war cry. The President's Bodyguard, the senior-most regiment (see our President's Bodyguard note), is one unit, not a family of battalions.
- "Brigade of the Guards" is a regiment, not a brigade. PIB lists it beside the Jat Regiment and the Garhwal Rifles among the regimental contingents on Kartavya Path (Jan 2025).
- "Regiment of Artillery" is an arm, the family of all gunners (PIB writes officers as "THE REGIMENT OF ARTILLERY"), and a "Field Regiment" is one unit inside it.
- A battalion moves between brigades, never between regiments.
The Rashtriya Rifles Model: One Force, Many Parent Regiments
The Rashtriya Rifles (RR) were raised on 1 October 1990 by the then Chief of the Army Staff, General VN Sharma, for counter-insurgency (PIB, 2015). PIB says continued counter-insurgency duty on top of the conventional threat "warranted a specially structured and organised force". Three of the first six battalions went to Punjab and three to Jammu and Kashmir; later all moved to J&K (PIB, 2015).
The model is the opposite of the infantry regiment. The RR was raised with 100 per cent personnel on deputation from the Indian Army, from all arms and services, on an all-India, all-class basis (PIB, 2015). A soldier from the Garhwal Rifles or the Corps of Engineers serves in an RR battalion for a tour and carries his parent regiment's name. PIB's gallantry lists show it: "The Garhwal Rifles, 36 Rashtriya Rifles", "The Corps of Engineers, 57 Rashtriya Rifles" (Aug 2026). So RR battalions are numbered units with no single parent regiment.
| Level | What it is | Commander |
|---|---|---|
| RR battalion | A numbered unit, such as 36 RR, manned from many regiments and arms | Colonel, as in other battalions |
| RR Sector | Several battalions, much as a brigade; PIB career notes mention a "Rashtriya Rifles Sector" with a deputy commander | Brigadier (press: "Commander 9 Sector RR", The Tribune) |
| Counter Insurgency Force (CIF) | A headquarters running several Sectors; PIB lists "Headquarters Counter Insurgency Force (Romeo)" under a Major General (Jan 2026) | Major General, the GOC |
Press and reference accounts name five Force headquarters: Victor, Delta, Kilo, Romeo and Uniform (The Tribune, ThePrint, ANI). PIB itself names only Romeo in the sources we checked. Areas have changed over time, so we give no deployments. Learn the five names; each is a Force under a Major General, not a regiment. The Forces sit in Northern Command; see our commands page.
The RR is part of the Indian Army, unlike the Assam Rifles, which is a Central Armed Police Force. PIB's 2015 note says it was raised with "100% personnel on deputation from the Indian Army, from all Arms and services". Raising year: 1990.
Territorial Army, Para (SF) and Bhairav Battalions
Territorial Army (TA). A part-time volunteer force: on 6 August 2026 the Raksha Mantri called it "a living embodiment of the 'Citizen-Soldier' concept", and PIB gave it as approximately 44,400 personnel and 59 units. Its Ecological Task Forces have planted about 10 crore saplings (PIB, 6 Aug 2026), and PIB has mentioned an Eco-Territorial Army battalion on the Namami Gange project (Jun 2023). Our Territorial Army page covers how to join, and our Terrier Cyber Quest note shows one recent activity.
Para (Special Forces). PIB writes the Special Forces as battalions of the Parachute Regiment: "9 PARA (SF)", "11 PARA (SF)", "21 PARA (SPECIAL FORCES)", and says an officer was "commissioned into 4th Battalion, The Parachute Regiment (Special Forces)". Same pattern as the infantry: the Parachute Regiment is the family, "9 PARA (SF)" one battalion.
Bhairav. On 26 July 2025 PIB recorded the Army chief naming Bhairav light commando battalions. At the Army Day parade at Jaipur on 15 January 2026, two Bhairav contingents marched for the first time, drawn from the Rajputana Rifles and the Sikh Light Infantry, described as a "lean and mean" force built for rapid, high-impact operations along the borders (PIB). So the Bhairav units marched under infantry regiment names, while PIB writes the Special Forces as "PARA (SF)". PIB gives no Bhairav strength or count. Our note on Exercise Mountain Guardian follows one Bhairav Battalion with the UAE Army, and the special forces page sets the Para (SF) battalions beside the other elite units.
- 13 Nov 2025: a Rudra Brigade takes part in Exercise Akhand Prahaar (PIB).
- 15 Jan 2026: two Bhairav Battalion contingents march at the Army Day parade for the first time (PIB).
- 30 Jun 2026: PIB lists Rudra Brigades, Bhairav Battalions and Electronic Warfare Brigades among reforms progressed.
- 6 Aug 2026: PIB gives the Territorial Army as about 44,400 personnel and 59 units.
- 5 Oct 2026: a Bhairav Battalion joins Exercise Mountain Guardian with the UAE Army (PIB).
Exam pins
- Brigade = 3 battalions (NIOS), commanded by a Brigadier (equivalent: Commodore, Air Commodore).
- Battalion = 4 companies (NIOS), the infantry's main fighting unit, commanded by a Colonel, the CO.
- Infantry regiment = parent family with a Regimental Centre; armour and artillery regiment = a unit of battalion size.
- A battalion changes brigade, never regiment. A brigade holds battalions of different regiments.
- 13 KUMAON = 13th Battalion, Kumaon Regiment. 1/11 GR = 1st Battalion, 11th Gorkha Rifles (battalion first).
- Brigade of the Guards is a regiment; Regiment of Artillery is an arm.
- Independent brigade: outside a division, written "(Independent)" or "(I)".
- Rashtriya Rifles: raised 1 October 1990 by Gen VN Sharma, manned on deputation from all arms, all-India all-class; part of the Army.
- Five RR Force headquarters in press: Victor, Delta, Kilo, Romeo, Uniform, each under a Major General.
- Territorial Army: about 44,400 personnel, 59 units (PIB, 6 Aug 2026).
- Rudra = all-arms brigades; Bhairav = light commando battalions; both announced 26 Jul 2025.
Asked in past papers
Few past papers touch this rung head-on, so these four are the nearest.
Jammu and Kashmir Light Infantry is
(a) A Central Paramilitary Force (b) A force maintained by the state of Jammu and Kashmir (c) A regiment of the Indian Army (d) None of the above
Answer: (c). It is an infantry regiment, a parent family that raises battalions. The name tempts a candidate towards a state or paramilitary force.
The equivalent rank of Commodore of Indian Navy in the Indian Army is
(a) Brigadier (b) Lieutenant Colonel (c) Colonel (d) Major General
Answer: (a). The Commodore is a one-star rank, like the Brigadier who commands a brigade. The stored key was blank; the rank-equivalence table gives Brigadier. Colonel is the tempting wrong option: it is the rank of a battalion's CO, one step lower.
Consider the following statements about Exercise Khaan Quest, 2026: 1. The Indian Army contingent comprises 40 personnel, including troops from a battalion of the Sikh Regiment and personnel from other Arms and Services 2. The aim of the Exercise is to prepare contingents of participating Defence Forces for peacekeeping missions while operating in a multilateral environment
(a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2
Answer: (b). PIB records that the 40-strong contingent came from a battalion of the JAT Regiment, so statement 1 is wrong. Statement 2 is right: the exercise trains for peacekeeping.
Which of the following are administered under the Ministry of Defence, Government of India? 1. Territorial Army 2. Hydrographic surveys and preparation of navigational charts 3. National Cadet Corps 4. All matters relating to Coast Guard Organization
(a) 1, 2, 3 and 4 (b) 1, 3 and 4 only (c) 2 and 4 only (d) 1 and 3 only
Answer: (a). All four appear in the Ministry's allocation of business. Option (c) drops the TA and the NCC.

Where to Go Next
The rung above is the divisions page; the whole ladder is on the hierarchy page. Next, read the infantry regiments page for each family. The career in the Indian Army page shows where an officer first commands a unit. SSB candidates are asked "which arm will you choose and why", so read our SSB interview tips with this page open. For revision, see the NDA study material and the CDS/OTA study material, and our CDS/OTA coaching batches take you through the Army's structure with PYQ drills and weekly tests.
Frequently asked questions
How many battalions are there in an Indian Army brigade?
The NIOS military studies text says three battalions form a brigade, under a Brigadier. Around them sit artillery, engineers, signals, supply and medical support. The Army publishes no strength figure; one press explainer gives about 3,000 troops, while other books give up to 5,000.
What is the difference between a regiment and a battalion in the Indian Army?
In the infantry, a regiment is the parent family, such as the Sikh Regiment or the Kumaon Regiment, with a Regimental Centre that trains recruits. A battalion is the unit that fights and is posted to a brigade. In the Armoured Corps and the artillery, a regiment is a battalion-sized unit, not a family.
What does 13 Kumaon or 1/11 GR mean?
The number comes first and the regiment second: 13 Kumaon is the 13th Battalion of the Kumaon Regiment. The Gorkha Rifles number their regiments, so they write battalion first and regiment second. 1/11 GR is the 1st Battalion of the 11th Gorkha Rifles.
What is the Rashtriya Rifles and how is it different from an infantry regiment?
The Rashtriya Rifles is an Indian Army counter-insurgency force raised on 1 October 1990 by General VN Sharma. Its personnel come on deputation from all arms and services of the Army, on an all-India, all-class basis, so its battalions have no single parent regiment. Press names five Force headquarters: Victor, Delta, Kilo, Romeo and Uniform, each under a Major General.
What are Rudra brigades and Bhairav battalions?
PIB records that the Army chief announced Rudra all-arms brigades and Bhairav light commando battalions on 26 July 2025. A Rudra brigade brings several arms under one commander, and a Bhairav battalion is a lean battalion for rapid border operations, drawn from infantry regiments. PIB writes Special Forces battalions as PARA (SF), not as Bhairav, and gives no count of either new formation.
