One of my teachers fought in Iraq. (Or Afghan Not sure) He was a Medic, and he told us what exactly what his Crew did. Him and his men Disarmed bombs from the insurgents (what ever they are called) that they found. He showed us a video they shot, It was terrible sounding. We heard gunfire in the backround, and the camera turned over to this one persons face, He looked young maybe 25. His face was terrified.
War isn't a pretty thing. My cousin is in the marines, He disarms mines. and its terrifying for him. My word of advice is this: He our sacrificed him self for his country, and he is/will be honored for it. and His sacrifice lead to the end of his arm.
Tell' em your fathers a brave man. And Is a hero to our country.
