Indian Army at regular intervals undertakes such battle exercises at different levels to ensure forces are provided war-like situations and kept in high-state of battle readiness as part of so called Cold Start Doctrine.
The doctrine involves the various branches of India’s military conducting offensive operations against enemy (mainly Pakistan) as part of unified battle groups. It would involve limited, rapid armoured thrusts, with infantry and necessary air support. Under it, the offensive operations must begin within 48 hours after orders have been issued. Such a limited response time would enable Indian forces to surprise their enemy. It is intended to allow India’s conventional forces to perform holding attacks in order to prevent a nuclear retaliation from the enemy.
