The book offers deep insights into the ongoing transformation of the Indian armed forces, driven by jointness, integration and self-reliance, to meet the demands of 21st century warfare and secure national interests, HQs Integrated Defence Staff (IDS) said. The book is rare as it has been authored by a serving four-star officer.
