This hearing reflex is due to the response of the inferior colliculus located at the back of the midbrain to stimuli such as noise. Basically, the inferior colliculus is the main auditorium of the human body. External sounds travel as sensory-auditory signals to the inferior colliculus through electrochemical currents so that they can process this information to the central brain. It consist of two front lobes corresponding to both ears. It regulates frequency recognition, pitch discrimination and signal integration. This is also what facilitates your selective hearing where you cannot hear your self-induced sounds like breathing and chewing.
        
             
        
        
        
Modern day warfare is caused by the same reason as with what happened at Thermopylae when Spartans fought against Persians. The only difference between today and the past is that we are now educated people with human rights and decency. Civilizations have evolved and progressed over the years. In my own opinion, NO, it would not create the same kind of heroes as before just because of some greedy ambitions and self-interest.
Hope this helps. Have a nice day!
