Training in trauma medicine is a must IMO. I have a small trauma kit I carry in a cargo pocket. It has just a few items that can mean the difference between life and death. I keep this kit when I'm in uniform or not. My kit was put together by Dr. John Meade, it's not too bulky and one of the items I train with the most is the tourniquet, but you be surprised what you can do with duct tape! I will be repeating two medical courses over the next year. Yes, I think they are that important.
