One shot, one IED, and that's all the excuse they need to cut loose. If the Marines back away from their usual *We can do it all ourselves, our way, we're Marines* attitude, and there are a couple of good reasons for them to consider a change from that SOP in this instance, it could be an example of the best possible world in Marine professionalism overcoming Marine image. We shall see.
God Bless all of our troops carrying loaded weapons in harms way!!
