General Manoj Mukund Naravane on Tuesday took over as the 28th Chief of Army Staff, helming the 1.3 million-strong force at a time India faces evolving security challenges such as cross-border terrorism and an assertive Chinese military along the border. Gen Naravane, who was serving as vice chief of the Army, succeeds Gen Bipin Rawat, appointed the country’s first Chief of Defence Staff, a post created to bring in operational convergence among the three services.
