“Train as you fight, and fight as you train” has been the mantra of the armed forces worldwide and is central to planning training exercises. But keeping troops combat‑effective is costly: every bullet, missile and shell fired hits the defence budget.Live weapons, heavy equipment and movement across difficult terrain also increase the dangers of “train as you fight” training.To reduce both risk and cost, militaries are increasingly turning to simulators to teach complex tasks and improve efficiency on weapons that can cost lakhs or even crores.Modern forces, including the Indian Armed Forces, are undergoing a significant shift. Technologies increasingly enhanced by artificial intelligence (AI) are central to preparing troops for conflict. Live‑fire exercises, while valuable, involve safety restrictions. The same scenarios run on simulators cost far less and are much safer.Beyond the price of expensive projectiles, simulators reduce wear and tear on systems: a main‑battle‑tank barrel, for example, is rated for only a few hundred high‑velocity rounds, and each training shot shortens that life. Similarly, practising with an air‑defence system in the real world can involve missiles that cost crores, flying targets that cost lakhs, and operational strains that together can push an exercise into crores — or drain foreign reserves.The Army uses a range of simulators to train soldiers. It is seeking gunnery simulators for its T‑72 and T‑90 tanks, and already uses simulators for missile and weapons training.Simulators also let forces practise drills that would be too dangerous in reality. Pilots regularly train for engine failure and other emergencies in simulators, giving them live‑like exposure to life‑threatening situations in a safe, controlled environment.AI adds another layer of sophistication by adapting scenarios to individual performance, creating unpredictable adversary behaviour, and delivering detailed analytics that help instructors identify mistakes and tailor feedback. That makes training not only more realistic, but also personalised and continuously evolving.Simulation benefits extend across domains: they replicate diverse operational environments, support integrated multi‑domain training, and record every action to provide objective benchmarks for skill refinement. AI‑powered simulation is becoming indispensable to modern armed forces.
