"Every time you go into battle, you are scared shitless. The panic will rise inside of you and you have to develop a technique to keep it down. The trick is to keep your fears under control. First, you have to know your fears. There are several kinds of fear a combat soldier has to deal with: First of all, there is a 'deployment or mission fear.' This starts the day when you get your orders to go into combat. It's like a fist in the stomach. From this day on, until you come back home to safety you will feel this fear. Sometimes it's just a gloomy feeling, the certainty that you are doomed and sometimes, it makes you wake up in the morning with thoughts like: "Fuck! What have I done?!" This fear is the easiest to control. Keep busy, avoid moments of lineliness and stay focused on the task at hand. Fortunately, as soon as a soldier gets his or her marching orders, life becomes very busy and there isn't much time to start with deep thinking, anyway."
