I to draw a man taking cover and being shot at in a battle because that happens in war, people get shot at on a daily bases. The ones who survived the surprise attack against the Soviet Union, if they lived though Germany attacking in the west on May 10, 1940. they go to next battle. Its not easy to take someone's life so it take a on someone's mind, so when they finality get to stop fighting the battles they aren't the same person.
