Territorial Army: Structure, Functions & UPSC Guide

The Territorial Army (TA) is India's "Citizens' Army" — a second line of defence composed of volunteers who maintain regular civilian careers but undergo military training and can be called up for service when needed. Founded on October 9, 1949, the TA provides India with a reserve military force that can be mobilised during emergencies without maintaining the full cost of a permanent army.

For UPSC, the Territorial Army is a frequently tested Defence topic — particularly around its structure, functions, and famous TA officers.

Overview

The Territorial Army is not a separate branch — it is an integral part of the Regular Army but composed of volunteers rather than full-time professional soldiers.

History

Pre-Independence

India had a tradition of volunteer military service during colonial rule:

• Indian Volunteer Corps (1917) — during WWI
• Indian Territorial Force (1920) — precursor of the current TA

Post-Independence

After independence, the Territorial Army Act, 1948 was passed to establish a modern TA:

• Bill introduced by Prime Minister Jawaharlal Nehru
• Inaugurated by President Dr. Rajendra Prasad on October 9, 1949
• Modelled partly on the British Territorial Army (now Army Reserve)
