The Infantry of the Indian Army is the largest arm of the Indian Army. It consists of personnel, who historically have engaged in ground combat on foot. It presently also consists of mechanised and airborne infantry.

History The infantry was historically the first combat arm in any army. The present regiments of the Indian Army trace their origin to the British East India Company, when Indians were employed to protect their trading stations. From the middle of the eighteenth century, the three presidencies of the company began to maintain armies at Calcutta (Bengal Army), Madras (Madras Army) and Bombay (Bombay Army). The presidency armies had their own Regiments and cadre of European officers. There were European regiments, where both the officers and men were Europeans, as well as 'Native' regiments, which were officered by Europeans, but the other ranks were Indians. The recruitment of Indians was usually done locally, with battalions each drawn from single castes, or and from specific communities or geographical areas. This pattern of recruitment continues to this day in many of the older regiments. Following the Indian Rebellion of 1857, 55 out of 70 infantry regiments of the Bengal Army were disbanded and more infantry regiment raised from Punjab and those including Gorkhas. Indian troops maintained internal security in the country, fought for the defence of the North-West Frontier and were sent abroad to take part many conflict zones of the British empire. The infantrymen subsequently served in the two world wars with distinction.

Regimental organisation Each regiment consists of more than one infantry battalion. A battalion is commanded by an officer of the rank of Colonel. The battalion is further divided into four rifle companies, one headquarters company and at times a support company. Each company is commanded by an officer of the rank of a Major or a Captain. A company will have three platoons, which in turn will have three sections. In addition, each battalion has a Ghatak platoon, which is a special operations capable reconnaissance platoon. An infantry battalion usually has a strength of 15-20 officers and 650-800 other ranks. The latter includes Junior Commissioned Officers (JCOs), Non Commissioned Officers (NCOs) and other ranks (ORs).

New formations and units

From 2025, keeping in nature of the evolving nature of the battlefield, a drone platoon would be introduced to each infantry battalion in the service. Each 'Ashni drone platoon' would employ 20–25 soldiers and be equipped with loitering munitions and drones to perform intelligence, surveillance and reconnaissance (ISR) roles. In addition, 'Bhairav Light Commando Battalions' are being raised. This battalion would have a strength of 250 personnel, including 78 officers, which is much lesser than that of a standard infantry battalion or a Parachute Regiment battalion, which include 800 and 620 soldiers each. These agile and compact battalions, evolving from the Ghatak platoon concept, are designed as shock troops to undertake clandestine missions or deliver surprise strikes under high-risk conditions beyond the enemy lines to inflict maximum damage.

Regiments The Indian Army has four types of regiments based on class composition - Single Class- These regiments have troops from a single class, e.g. Dogra Regiment. This group also includes three scout units (highlighted in green), which are affiliated with an existing regiment. These units includes recruits only from a small geographical area and have a role of serving only in the border region from where they have been raised. Fixed Class - They are composed of troops from two or more ethnic groups. The sub-units have troops from a single ethnic group e.g. Rajputana Rifles are recruited primarily from Jat and Rajput populations. Mixed Fixed Class - They are similar to the Fixed Class regiments but the sub-units have troops from more than one ethnicity. e.g. the Punjab Regiment comprises Sikhs, Punjabis and Dogras but all function in mixed sub-units. All India All Class- These units contain a heterogeneous mix of all Indian classes and are generally those units, which have been raised after independence. e.g. Brigade of the Guards. Based on role, the regiments can be classified as- Regular infantry Airborne infantry Mechanised Infantry The regiments, date of formation, regimental centre, number of battalions (regular, Territorial Army (TA) and Rashtriya Rifles (RR), motto and war cry are as follows.

Infantry School

The Infantry School is the oldest and largest training institution of the Indian Army, training over 7,000 Officers, Junior Commissioned Officers and Non-Commissioned Officers annually. The origin of the present school can be traced to The School of Musketry at Changla Gali (now in Pakistan), which was established in the year 1886. Between 1886 and 1948, before it inherited its present name and came to be located at Mhow, Madhya Pradesh, it passed through various names and locations: - +YearNameLoc1886School of MusketryChangla Gali1888School of MusketryDeolali1913School of MusketrySatara and Belgaum1919Small Arms SchoolPachmarhi1931Small Arms SchoolAhmednagar1933Small Arms SchoolSaugar1935Indian NCO Training SchoolJhansi1937Indian Infantry Platoon Commander's SchoolFaizabad1940Battle School and Tactics and Administration SchoolDehradun1948Infantry SchoolMhow
