When we think about modern warfare, we often picture drones, artificial intelligence and cutting-edge technology. But behind every mission is a person whose physical fitness, mental resilience and decision-making can mean the difference between success and failure. In this episode, Dr Peter Wright explores the science of human performance and explains why soldiers are better thought of as "tactical athletes", people who must combine strength, endurance, resilience and cognitive performance in some of the world's most demanding environments. From sleep and nutrition to wearable technology and the future of military research, discover why looking after the human behind the mission isn't just important for soldiers, it contains lessons that can help all of us perform at our best.
