At the Nellis Air Force Base in Nevada, pilots from six different nations gather for Red Flag, the world's largest and most intense air combat training exercise. Over the course of fourteen days, these elite crews engage in simulated air warfare, pushing their skills and their aircraft to the absolute limit. The exercise is designed to provide pilots with their first ten combat missions in a controlled, realistic environment, preparing them for the high-stakes reality of actual combat where the margin for error is nonexistent.
