Combat on television vs. real life
Combat is nothing like television. What is seen with the eye may appear the same. An explosion in a movie is no different than an explosion seen by the naked eye, but it's the other four senses that truly define combat. The smells of gunfire. The loud ping of bullets bouncing off of metal. The vibrations of grenades exploding nearby. The taste of your own fear climbing up into your throat. This is combat. And no matter how many times you experience it, you learn one more thing about yourself and you're always happy to be walking away.
