The Indian Army, being the largest part of The Indian armed forces, has a well planned and thought out Organizational structure, that outlines how certain activities are directed in order to achieve its goals i.e. to ensure national security, defend India from internal and external threats and maintain peace in its borders. This structure is not to be confused with the field formations i.e. commands, corps, divisions, brigades, battalions, companies, platoons and sections, but the different Arms and services of the Indian army that are entrusted with specific pan-army tasks.

Arms and Services

Apart from the Field Formations, the Indian army is further divided into two categories:-

(A) Combat Arms

(B) Support Services

First, I will explain about Combat arms to you and then we will cover the Support Services section in the Arms and services of the Indian army in 2021. Let’s take a look.

What are Combat Arms in the Indian Army?

Combat Arms are those forces of the Indian army that actually fights with the enemies on the battlefield and they are supported by different corps that aid them in bringing down the enemy forces and win the battle for India. Combat arms in the Arms and Services of the Indian Army is classified in two categories:

1) Infantry Regiments

2) Combat Arms corps

1) Infantry Regiments

Infantry regiments are those forces that take the fight to their enemies and fight them head-on, they are specialists in face-to-face battles. They are needed because all vehicles can’t go to each and every part of our territory and enemy territory, this unit explores those territories which are inhospitable.

Infantry plays a key role in capturing important targets inside bunkers which are military fortifications underground designed to protect people and valued goods from falling bombs or other attacks and the infantry troops also engaged in Counter-Insurgency and Counter-Terror Operations(Ops).

The Infantry Regiment has a total of 30 regiments and one mechanized infantry regiment. To name a few these are The Brigade of Guards, The Madras Regiment, The Parachute Regiment etc.


Mechanized Infantry

Mechanized infantry is the combination of both Infantry and Armoured Corps used by the army for transport and combat. This regiment has been active since April 02-1979. It is the youngest regiments in the Indian army, comprising 27 battalions dispersed under various armoured formations. It is equipped with armored personnel carriers (APCs) or infantry fighting vehicles (IFVs) which protect troops from hostile fires.

These vehicles can also be used as ambulances equipped with stretchers and medical supplies, in order to carry out injured personnel from war-prone areas.

2) Combat Arms Corps

(A) Armoured Corps

Armoured Corps is known as “The Tankmen“. The terms like “Cavalry”, “Lancers”, “Horses” are the namings of the Armoured regiments. Armoured troops followed behind the infantry on the battlefield on their tanks, which are the fighting vehicles designed for front-line combat which combines operational mobility and tactical offensive and defensive capabilities.

Armoured corps has in total 67 regiments including bodyguards of The President of India. 

According to tradition, each armoured regiment has its own “Colonel of the Regiment“, an honorary post for the senior rank officer who oversees the issues that occurs in the regimental units. The armoured corps is the most decorated corps of the Indian Army.

The Regiment of Artillery is the second-largest corps among the arms and services of the Indian Army and it is known as “gunners”, because of its guns, mortars, rocket artillery, unmanned aerial vehicles, the surface to surface missiles, surveillance systems, multiple rocket launchers, and air defense units and this all equipment contributes to one-sixth of artillery total strength.

The role of the Artillery is to provide supporting artillery fire to the Armoured Corps and the Infantry. Artillery comprises heavier long-range weapons that cause heavy damage to the enemies.
