On 13 November 2019, the Indian Army initiated a large-scale combat exercise on the western end of the Thar Desert in Rajasthan. Designated “Sindhu Sudarshan,” the large-scale wargame comprises of 40,000-plus troops alongside tanks, artillery and helicopters.[1]
According to an Indian Armed Forces officer (via The Times of India), the drill “aims to validate the battle readiness, operational effectiveness and deep strike offensive capabilities of the ‘Sudarshan Chakra’ (21) Corps in an integrated air-land battle scenario.”[2]
In other words, a key aspect of the exercise is to test the effectiveness of India’s ‘integrated battle groups’ (IBGs), which are meant to rapidly thrust into enemy territory through a composite force of infantry, tanks, artillery, and fixed as well as rotary aircraft, among other military assets.
This exercise is also serving as the first deployment or use of the Indian Army’s newly inducted Hindustan Aeronautics Limited (HAL) Rudra lightweight utility helicopters and the Vajra 155 mm/52-calibre tracked self-propelled howitzer (SPH), the latter being based on the Hanwha Land Systems K9 Thunder SPH.[3]
India’s Emerging Integrated Battle Groups
Though deployed, the IBG concept is still a work in progress. Currently, Indian officials believe it will take around four to five years to fully convert selected units into IBGs (The Economic Times).[4]
