Which type of training involves both simulation and physical activities in a realistic environment?

Live training incorporates both simulation and physical activities within a realistic environment, making it the correct answer. This type of training is essential for preparing personnel for real-world scenarios, allowing them to engage in hands-on experiences that closely mimic actual operational conditions. By combining real-life physical elements with simulated components, participants gain valuable practical skills and situational awareness that are critical for effective performance in their roles.

In live training scenarios, individuals can practice various tactics, techniques, and procedures while interacting with real people and equipment, which enhances their readiness and effectiveness in actual missions.
