The Indian Army plans to operationalise its first Integrated Battle Groups (IBGs) from 1 July 2026 under the XVII Corps (Mountain Strike Corps) at Panagarh, West Bengal.
An IBG is a brigade-sized, self-contained combat formation with 5,000+ troops, integrating infantry, artillery, engineers, signals, air defence, logistics and medical units under one command.
The IBGs are designed for rapid mobilisation (within 48 hours) and offensive and defensive operations, especially along the China border in mountainous terrain.
The concept was proposed by General Bipin Rawat and was first tested in 2019 in IX Corps and Exercise HimVijay.
The Army plans to complete IBGisation by 2029 as part of its wider force modernisation, alongside Rudra Brigades, Bhairav Battalions, Divyastra Batteries and Shaktibaan units.
