Here is a story about what my Nephew went through in Iraq.
He came home in September of 2005 with two purple hearts, after the Bradley he was patroling in was hit with IED's on two separate occasions. In both incidents he was the guy with his head and upper torso out of the forward hatch. In the first incident he only received minor facial lacerations. The second incident resulted in him recieving second degree burns on his face, neck and shoulder areas.
I sat with him and we talked about what happened and I asked him what was the reaction of the guys with him when they were attacked. He tod me, "Unk, we wanted to kill everything and everyone in the area when that happened. The only thing that prevented it was kowing that we were under strict orders that we could not fire on anyone unless we were fired upon."
I then asked him how were they setting the bombs off. He then told me about how the terrorists used remote control devices, and would stand around with a group of people and activate the devise when the Bradley's or Humvees came upon them. He told me that this was the hardest thing to take when they were attacked. Knowing that the person who activated the IED was standing within 50 to 100 ft. of them and they could do nothing about it.
All I know is it takes a lot of discipline to not fire into a group of people, knowing that the person that just set off a device to try and kill you is in that area. War is hell and I can never pretend to know what the awfull conditions these young men and women are put through are like.
