Can PTSD travel through as information through a transatlantic cable if the combat simulations are obviously real and the loss of life is known to be real even though it is relayed through the eyes, ears and hands of drones? Or is PTSD a function of the fear of losing one's own life? Some say the PTSD isn't in losing one's own life, it's in the damage a man does to himself when the enemy [not picked by him in particular] losing their life and the one who pulled the trigger struggling and succeeding to disable your own cognitive dissonance, and when you're successful, you're unable to relate to fellow humans.
