Just type simulated weapons training into a web search engine and you will discover just the tip of the iceberg. Simulation has been an important part of training pilots to work with a particular combination and geometry of instrumentation in an aircraft. They learn to act automatically in response to the environment in the plane and outside. But this training is done outside of the military as well. Student lawyers simulate defending and hearing cases.
Student teachers practice teaching in front of their fellow students.
What they do decides what they become and how they will function in their future lives. Even secular literature is aware that what we do is what we become. Shakespeare was aware that doing is the key to becoming. Our actions lead to our habits, the ways that we will usually function. The one thing that the very diminished views of human relationships do demonstrate is that the question of relationship between human beings is enormously complex.
