Post-traumatic Stress Disorder

I read about post traumatic stress disorder (PTSD) from a health website called healthyplace. The article says that PTSD is caused when "the person experienced, witnessed, or was confronted with an event or events that involved actual or threatened death or serious injury, or a threat to the physical integrity of self or others and the person's response involved intense fear, helplessness, or horror." This happens when people go to war. PTSD is a serious psychological effect of war because people have to kill kids, they have to make a moral effort of killing people, and they are constantly scared they are going to get killed by Iraqi troops. They can get killed, that is the most helpless feeling. Having a bunch of guys shooting at you makes you very scared which is a major cause of PTSD. Also, the Iraqi people are used to seeing people shooting and reshooting is easier for them because it is part of their life, some soldiers go to war who have never seen death and they are not used to it and it is very horrible for them. US people are not used to living with war and death. The worst thing that happened to the USA was September 11th and that only happened in New York. In Iraq war and terrorism happens in every single town on a regular basis. Soldiers are just people, they are people and they are going to be scared when they see death and war. Going to Iraq is like suicide becuase they go they get shot and the bullets go through people and some people are USA marines, it doesn't matter how strong or how much training you go through, they are not used to receiving bullets. They are not made of steel and that scares them and gives them a sense of helplessness and that helplessness is a serious cause of PTSD which is a psychological effect of war.
