I have been a prehospital provider since 1992. In my life, I never thought that I would become a victim while in the field. I also thought that I knew the actions I had taken before in the field were right and done with good intention. I found out I was wrong on all accounts. You learn so much throughout this course in two short days, including tactics on how to handle these situations, as well as how NOT to handle them, in addition to learning some techniques to help get out of a violent situation. I recommend it from a student before going to the street up to the most experienced provider.
