Quick revision mind map

This topic of “Integrated Battle Group – Basis, Purpose, and Structure” is important from the perspective of the UPSC IAS Examination, which falls under General Studies Portion.

The basis for the concept of IBG

  • The Indian military undertook massive mobilisation after the terrorist attack on Parliament in 2001.
  • but the Army’s formations which were deep inside took weeks to mobilise losing the element of surprise.

Cold Start Doctrine:

  • Following this, the Army formulated a proactive doctrine known as ‘Cold Start’ to launch a swift offensive, but its existence was consistently denied in the past.
  • Its existence was acknowledged for the first time by (Late) Gen Rawat in January 2017.

What are IBGs?

  • IBGs are brigade-sized, agile, self-sufficient combat formations, which can swiftly launch strikes against adversaries in case of hostilities.
  • Each IBG would be tailor-made based on Threat, Terrain and Task and resources will be allotted based on the three Ts.
  • They need to be light so they will be low on logistics.
  • They will be able to mobilise within 12-48 hrs based on the location.

Command, corps, and the brigade

  • While a command is the largest static formation of the Army spread across defined geography, a corps is the largest mobile formation.
  • Typically, each corps has three divisions, and each division has three brigades.
  • The idea is to reorganise them into IBGs which are brigade-sized units but have all the essential elements like infantry, armoured, artillery and air defence embedded together based on the three Ts.
  • An IBG operating in a desert needs to be constituted differently from an IBG working in the mountains.
  • The key corps of the Army is likely to be reorganised into 1-3 IBGs.

Types and composition of IBGs

  • The IBGs will also be defensive and offensive.
  • While the offensive IBGs would quickly mobilise and make a thrust into enemy territory for strikes, defensive IBGs would hold ground at vulnerable points or where enemy action is expected.
  • The composition of the IBGs would also depend on this.


  • The Indian Army is set to make far-reaching changes in its organisational structure for combat with some corps, divisions, and brigades replaced by smaller and self-contained Integrated Battle Groups, with airpower, armour, and artillery.
